Re: [PHP] Static methods vs. plain functions
2013/9/19 Simon Dániel simondan...@gmail.com Hi, I am working on an OOP project, and cannot decide which way to follow when I have to write a simple function. For example, I want to write a function which generates a random string. In an OOP environtment, it is a matter of course to create a static class and a static method for that. But why? Isn't it more elegant, if I implement such a simple thing as a plain function? I'd say: Definitely! Not to mention that a function is more efficient than a class method. Actually I wouldn't be so sure about that. So, in object-oriented programming, what is the best practice to implement such a simple function? In strict-OOP [1] you would choose a static method, because functions are simply forbidden. However, PHP isn't strict about that by itself. So I for myself don't like the dogmatic We use classes and nothing else!-approach. If a function fits better, it's OK to be a function. [1] Actually that would end up in a mix of OOP and class-oriented programming, which isn't that strict. -- github.com/KingCrunch
Re: [PHP] Static methods vs. plain functions
2013/9/19 Aziz Saleh azizsa...@gmail.com I think that it would be more elegant if you are already in a OOP to keep the flow and stick to OOP. It just doesn't make sense to me in an environment that uses OOP to have functions laying around. buzzword: multi-paradigm. Thats why it could make sense ;) Personally I like to group similar functionality together in their own objects, - That aren't objects, but classes. Actually you don't programm in object-oriented, but in class-oriented (or probably a mix) - You can (imo should) use namespaces this way I can reuse them on different projects, the random string generator is an excellent example of something I usually use in almost all of my projects. Function calling is usually faster than object calling (depends on how you benchmark it) since there is an overhead to it. There are some who tried to benchmark this and had opposite results, It all comes down to how are you going to use that functionality: http://www.webhostingtalk.com/showthread.php?t=538076 http://www.micro-optimization.com/global-function-vs-static-method Personally in my projects - specifically if I use a framework, I try to stay away from making standalone functions unless absolutely necessary.

Re: [PHP] high traffic websites
2013/9/18 Negin Nickparsa nickpa...@gmail.com In general, what are the best ways to handle high traffic websites? VPS(clouds)? web analyzers? dedicated servers? distributed memory cache?

Re: [PHP] high traffic websites
2013/9/18 Negin Nickparsa nickpa...@gmail.com Thank you Camilo to be more in details,suppose the website has 80,000 users and each page takes 200 ms to be rendered and you have thousand hits in a second so we want to reduce the time of rendering. is there any way to reduce the rendering time? Read about frontend-/proxy-caching (Nginx, Varnish) and ESI/SSI-include (also NGinx and Varnish ;)). The idea is simply If you don't have to process on every request in the backend, don't process it in the backend on every request. But maybe you mixed up some words, because the rendering time is the time consumed by the renderer within the browser (HTML and CSS). This you can improve, if you improve your HTML/CSS :) I am a little bit curious: Do you _really_ have 1000 requests/second, or do you just throw some numbers in? ;) other thing is suppose they want to upload files simultaneously and the videos are in the website not on another server like YouTube and so streams are really consuming the bandwidth. Well, if there are streams, there are streams. I cannot imagine, that there is another way someone can stream a video without downloading it. Also,It is troublesome to get backups,when getting backups you have problem of lock backing up with bulk of data. Even in times, where there is not that much traffix? Automatic backup at 3:00 in the morning for example?

That means that there'll be no tight coupling between Optimizer+ and PHP; Those who wish to use another opcode cache will be able to do so, by not loading Optimizer+ and loading another opcode cache instead. As per the Suggested Roadmap above, we might want to review this decision in the future; There might be room for further performance or functionality gains from tighter integration; None are known at this point, and they're beyond the scope of this RFC.

There is no other way around this than a different operator for method calls. I didn't think of that. It seems to me there could be an easier operator than - which sometimes will make me stop and look at what keys I'm trying to hit. Just a thought. I forgot about the concatenation operator which is + in Java/C# The PHP language developers were pretty stuck. Because of automatic string-to-numeric-conversion, they couldn't use + for string concatenation. Sadly, they chose . rather than .. which I believe one or two other languages use. If they had, . would have been available once objects rolled around in PHP 4/5. I suspect they chose - since that's used in C and C++ to dereference a pointer. Actually I think .. is quite error-prone, because it is hard to distinguish from . or _ on the _first_ glance, which makes the get quickly through the code. [1] So . is maybe not the best choice, but also remember when it was introduced: That was decades ago. That time it was (probably ;)) the best choice and nowadays I don't think it is too bad at all, beside that _other_ languages use it for other purposes now ;) [1] Yes, I know, that _ is not an operator, but mixed with strings and variables names it is there ;) Ever tried the jetbrains products? :D (No, they don't pay me) I have not, but it looks interesting. I'll have to try it. Those are very good products which have had a strong following for a decade. The free IDE NetBeans also has quite good support for both Java and PHP, and the latest beta version provides a web project that provides front- and back-end debugging of PHP + JavaScript. You can be stepping through JS code and hit an AJAX call and then seamlessly step through the PHP code that handles it. I use NetBeans for PHP/HTML/JS (though I am evaluating JetBrains' PHPStorm now) and Eclipse for Java. You can't beat Eclipse's refactoring support in a free tool, though I think NetBeans is close to catching up. I would bet IntelliJ IDEA for Java by JetBrains is on par at least. Eclipse' code-completion and debugger never worked for me well (and most of the time: at all). It became slower and less responsive with every release. That was the reason I decided to leave it and I don't regret it :) Peace, David -- github.com/KingCrunch

Re: [PHP] Re: PHP vs JAVA
2013/8/21 Curtis Maurand cur...@maurand.com Sorry in advance for the top post. Use the right tool for the Job. I've use Java, C# and PHP. 1. I hate the Perl-like object calls in PHP. I'd rather use . notation in C# and Java. It saves a lot of wear and tear on my left pinky finger. Actually the problem is, that the dot . is already in use. With $foo.bar() you cannot tell, if you want to call the method bar() on the object $foo, or if you want to concatenate the value of $foo to the result of the function bar(). There is no other way around this than a different operator for method calls. 2. Java and C# are both typed languages. Say what you want, but I have working with a string like 02 and have PHP convert that to an integer. sometimes I want that zero in front. If I want that to be an integer in Java it's int myInteger = Integer.parseInt(02); 3. Java development environments (Eclipses, NetBeans, IBM RAD) are pretty horrible. Visual Studio is hands down a better envrionment, even the older versions of it. I've hooked Visual Studio into SVN in the past and it works well. Ever tried the jetbrains products? :D (No, they don't pay me) 4 PHP development environments are many and varied and all of them suck at web debugging. I've used PHPEdit, Zend, Bluefish, Eclipse and a couple others. Bluefish works better on Linux than it does on Windows. I use PhpStorm and it works quite fine. Use the tool for the job at hand.

The number of websites powered by PHP vastly exceeds Java and every other language http://w3techs.com/**technologies/overview/**programming_language/allhttp://w3techs.com/technologies/overview/programming_language/all Says it all! But you would never use PHP for a distributed application, and then http://www.langpop.com/ comes into play when the fight is between Java and C/C++ and personally I'm happier with C/C++ than Java even on Android. But even though you would not use PHP for distributed applications, it still gets a good 4th in that chart as well. Exactly, but the initial explicitly states, that this is about web development :D Don't know, what I should think about langpop.com.

Re: [PHP] PHP vs JAVA
2013/8/20 Andy McKenzie amckenz...@gmail.com I'll chime in on this one. I've been job hunting recently, and I can say that while I've seen a lot of people asking for Java experience, I'm not sure I've seen a single posting asking specifically for PHP. There've been a few looking for Drupal, or Wordpress, but no You must be able to write PHP code to work here. Thats interesting. I am from Berlin and here, when you say you know PHP and a little bit of one, or two frameworks, they will jump onto you :D I can also say that the more I work with Java-based programs, the more I want to see Java written into history books as a terrible idea that sadly persisted until nearly 2014. As an example: I need to provide IT support to people using a tool written in Java. It turns out that if you install Java 7, the tool doesn't work at all. If you install Java 6 with the newest updates, it works, but occasionally crashes the entire computer. No, you have to have Java 6 update 22 in order for this software to be reliable. There are other tools I've used that failed completely on minor version switches, and that just plain SHOULDN'T HAPPEN. Yes, there are going to be minor changes when a language upgrades, that's why there are upgrades. But they're usually minor, in a This didn't work the way it was supposed to, so we fixed it kind of way. If you were taking advantage of that bug, you get knocked down, but the vast majority of software will keep running. Java doesn't seem to work that way, at least from an IT worker's perspective.

Re: [PHP] PHP vs JAVA
2013/8/20 Steven Staples sstap...@mnsi.net My recent question was simply an attempt to get documentation to support which server-side Web Language is the most popular. Both PHP and Java can be used server-side. I also realize that Java is used for native Android because I also teach Mobile Application Development (MAD -- I even coined the name). So, I am up to my butt in languages (and people who think different than me) -- I'm just trying to get documentation to back up my what I think I know. Well, technically any language can be used server side, it is all on how you set up your server, no? No. But since node.js I lack an example :D But of course you need the link between the language and the network. I would tend to think that the biggest out there, is html/php/javascript... and next to that, would be asp, and then java. Do I have proof of this? No, can I get proof, I doubt it, and are there stats on this? To be honest, in my opinion, that would be like asking how big is the internet?. It is virtually an immeasurable object. There are so many websites out there, that you can't search them all... Of course you cannot search them _all_, but again the link: http://w3techs.com/technologies/overview/programming_language/all There are good hints, how the internet looks like. For example a hoster can simply look at the products he sell. Services like w3techs.com use the reports from the server themself (in most cases the headers), or the file-ending (doesn't work anymore that good, since most sites hide them ;)) and extrapolate this. Of course they are not exact, but I think they show the direction quite accurate. PHP is simple, and yet powerful to use, and is pretty much the standard for all hosting companies. Now, there is this link... http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html It shows Java as #1, and php as #5, but this is also for PROGRAMMING, does not specify web based programming vs desktop vs MAD (thanks tedd ;) ) so the numbers do not really speak out in this application. Also it is the Tiobe-Index. Although it is widely-referenced, the way it calculates their rankings is ... interesting. In fact it only tells you how loud a community around a specific language is. So for example maybe Java is #1, because it is so complex, that it leads to many questions in forums and on stackoverflow. Or PHP is only #5, because most communication is on IRC, or mailinglists. (disclaimer: Of course I faked this examples. Actually I have no idea how the communities around Java and PHP as a whole interacts primary, but I don't think, that they are all equal). I just think, that the Tiobe-Index has a completely different view on what is a popular language, than I have. Does it really matter? PHP is very huge, widely used, and I would even go so far as to say the 'norm' for website developers, and hosting providers. Nope, it doesn't matter :) But that is my $0.02, and for me, I have been with PHP for 7 years professionally, and in college I took VB.net, ASP.net, C++, JAVA and PHP. Only recently have I gotten into C# for desktop applications. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- github.com/KingCrunch
Re: [PHP] how old is this version of PHP?
2013/8/19 Jeff Burcher j...@allredmetal.com I apologize if this is off topic, but this raises a question for me. Why can't new versions be backwards compatible? Is it really that difficult to accomplish? This has been a complaint of mine for years with Windows ever since we went from 95 to 98. I am an AS400 programmer and I have legacy programs written in RPG II, which died 20 years ago, and they still run fine on the newest version of AS400 or iSeries or Power System or whatever the heck it is called now. I also have PHP scripts that are many years old that work just fine the way they are, if a new version doesn't come along and make me have to reprogram for no reason just because it can't handle older code. Really, have Do loops and data calls changed that much over the years? I mean, all you do is set a condition, use a variable key field, and voila, data is pulled and processed, no big deal. Yeah, you can get fancy with it, but the core basics are still the same. I have been programming for over 35 years and like to think that once a program is built it should run forever. Do we just accept that we have to rewrite every program we ever wrote every time a new version comes out? A little extreme, but you get my point. Comments? Suggestions? My 2 cent: I hadn't any major issues with BC since 5.3 and from 5.2 it required a little bit to do, but was solveable (means: It wasn't complicated, but only an afternoon time to invest).

Re: [PHP] Class Auto-Assigning to Variable
2013/8/7 Brian Smither bhsmit...@gmail.com
I have a situation where, for some unknown reason, where each class that
finishes its __contruct{} function, that class gets automatically assigned
to a variable - other than the variable I specify.
Conceptually:
class Hello { private $_world = 'World'; __construct(){} }
This isn't even valid PHP
$ php -a
Interactive shell
php class Hello { private $_world = 'World'; __construct(){} }
PHP Parse error: syntax error, unexpected '__construct' (T_STRING),
expecting function (T_FUNCTION) in php shell code on line 1
php
$clsHello = new Hello();
echo 'The variable $hello is '.gettype($hello).\n.print_r($hello,true);
Output:
The variable $hello is object
Hello Object
(
[_world:Hello:private] = World
)
There is no statement in my application that assigns an instance of the
class to another variable, the name being a lowercase variant of the class
name.
Would there be a PHP function that would do this as a side-effect?
I am more interested in learning what is happening as opposed to rolling
back to a previous version. (A backup copy functions fine. A file compare
does not reveal any likely suspects.)

Re: [PHP] A Good OOP Tutorial/Read?
2013/5/17 Tedd Sperling tedd.sperl...@gmail.com
Nick:
I thank you for your addition, but what you provided did nothing to
explain the difference between abstract and interface.
In your example:
An abstract Shape with Circle and Square inheriting.
OR
An interface Shape with Circle and Square implementing.
Does exactly the same thing -- so where's the difference?
- The first one allows to contain implemented methods. Interfaces enforce
contract only, which makes them more stable on the long run. Sooner or
later (or right from the beginning) someone _will_ implement a method in
that class, which will loosen the separation between the contract and the
implementation. And then it begins, that it is hard to distinguish, what
from this class is contract (and should _never_ change without a good
reason) and what is implementation, that can change.
- It is semantically different as first one states Circle _is a_ Shape,
whereas interfaces defines their relationship more like Circle _behaves
like_ a Shape.
- In many languages you can only extend from one class.
Of course: Technically they do the same, but thats not the point ;) Also
technically you don't _require_ interfaces at all. As mentioned: Most of
this happens in ones mind. For example if you change an interface, you
should _always_ expect to break something ;)
Most of OOP isn't about syntax or technical features anyway, but it is
about concepts (design and so on).
And as a sidenote: I don't say (and don't believe ;)) that my explanation
is completely academically correct ;)
Also, your:
Please make an effort to understand polymorphic concepts of OOP as
they are rudimentary. Without that one will never grasp OO Patterns
(Gang of Four).
Was more insulting than helpful. Polymorphism was not the question asked.
Clearly the getArea() method is polymorphic and overridden in both Circle
and Shape classes and also in BOTH abstract and interface examples.
Additionally, I'm not sure what:
(int double side)
means.

Re: [PHP] A Good OOP Tutorial/Read?
2013/5/16 Tedd Sperling tedd.sperl...@gmail.com -Dan: I teach this stuff and still don't fully understand the why/when for interfaces. Even the guru's I talk with can't give me a good explanation as to what the advantages are in using them. I've done a lot of experimenting and can't see any advantage for them other than grouping different classes together and creating a new data-tytpe. An interface is like an contract: It doesn't do anything itself, but every class, that implements it must follow. This isn't only about the signature of the methods, but also about the semantics, which is ideally described directly in the methods comment (DocBlocks). On the other hand the class is completely free on how it fulfill the contract. For example: A QueueInterface. It probably defines the signatures for (at least) enqueue() and dequeue() and their semantics: enqueue() enqueues an element at the end of the queue and may fail with an XY-Exception, when the queue is full, deuqeue() dequeues an element from the front of the queue and throws an Z-Exception, when the queue is empty. An implementing class is free to implement this on top of a database, or an array, as well as the class is free to extend it with other methods as it like. Of course you could implement it as abstract class, but this leads (instantly, or later) to a mix between contract and implementation details, that (by the way) should be up to the implementing class anyway. Now that you have one, or more classes implementing that interface you can type hint against this contract and only against this one, because it is better to always hint against the most-simple type the methods requires. In this example this means: I, the method x(), expect a queue and I am completely uninterested in how it is implemented, or what other features it provides, because I don't use them anyway. Now you can give me a database-cursor, or a wrapped array as long as they _behave_ like a queue (-- implementing that interface). As a side effect: Sometimes it is more fail-safe, because if you change signatures, or add methods, you'll face the errors from wrongly implemented classes instantly ;) Oh: And you are not forced to extend a class :) Lets say I have a Comparable-interface and a User-Class. Would Comparable be a class, I have to extend it, which makes it impossible to extend any other class and also the semantic is wrong: A User _behaves_ like a Comparable, but it _is not_ a Comparable. (For me implementing an interface is usually more a behaves like, looks like, or provides, whereas extending a class is directly a is a-relationship). This said, the difference between an interface and an abstract class is mostly in the head: An abstract class is in my opinion never such a strict contract, like an interface, especially because you can always leave the contract-only-restriction by implementing something into the class, what is then directly inherited by the subclasses. My 2 cent :) But for me this idea works quite fine :D Regards, Sebastian Other than that, from my perspective interfaces are mythicode. So, if you find a good reference, please let me know.

If you really have that much traffic, then memcache isn't your answer to
caching. It is as slow as a fast database.
That's not entirely true.
You should use APC caching instead. APC will also handle a lot of
bytecode caching.
We have both.
If you want to go with tidy and surf around the php issues you could
optimize the single html parts, before glueing everything together.
That would require much more work than simply getting and to work. And
honestly I've been hacking around Tidy so much at this point with regex to
minify the output, that I'm even wondering if Tidy is worth the both
anymore. Not sure what else it will give me.
Maybe google page speed is worth a look for you too?
We have over 1,000 servers in house and also distributed across nodes in
various cities and countries.
Really? Ever considered HTTP-Caching, or even Load-Balancing including ESI?
With the loggedin flag, you can save two versions of your rendered, one
for loggedin users and for not logged in users. That saves you php code
in your template and you can use tidy. And for any other variables you
can load the dynamic data after the page load.
I gave simplistic examples for the sake of illustration.
With tidy, have you tried
http://tidy.sourceforge.net/docs/quickref.html#preserve-entities
http://tidy.sourceforge.net/docs/quickref.html#fix-uri
Yes. See below. I posted all the flags I have tried and I too thought
those were the key, but sadly not.

Well we get about 30,000 page hits PER SECOND.

Then we store THAT rendered page in a cache (memcache pool as well as a
local copy on each server).
HOWEVER, there are of course dynamic parts of the page that can't be
cached or we'd be making a cached page for every unique user. So things
like
their ?= $username ?, or maybe parts of the page change based up their
membership ?php if ($loggedin == true) { ?, or maybe parts of the page
rotate different content (modules if you like).
Therefore we are trying to mininimize/compress the cached pages that

other stuff. When you have this much data to serve that fast, those few

Re: [PHP] Newbie Question - Parse XML with PHP...
A webpage is a file, that (usually) a browser downloads and parses.
You'll do exactly the same :-) I don't know exactly, but you can try to
pass the URL directly to simplexml_load_file(). If this doesn't work,
download the content (for example with file_get_contents()) and pass it to
simplexml_load_string(). There are obviously many other approaches, but you
should now have an idea :-)
Or you use a specialized library like Guzzle.

You could use is_numeric for that, though it also accepts

for that type of test I have always used this:

http://www.php.net/manual/en/language.types.integer.php#language.types.integer.casting
I hope you're not serious about this...
When comparing a string and an int, PHP will translate the string
to int
too, and of course they will always be equal then.
So:
$a = abc;
if($a == (int)$a) echo YES;
else echo NO;
Will always return YES.
- Matijn
H... Interesting. Looking back at my code base where I thought
I was
doing that, turns out the final results were not that, but this:
$value = asdf1234;
if ( $value === (string)intval($value) ) {
Looking back at the OP's request and after a little further
searching,
it seems that there might be a better possible solution for what
the OP
is requesting.
?php
$values = array(asdf1234, 123.123, 123);
foreach ( $values AS $value ) {
echo $value;
if ( ctype_digit($value) ) {
echo ' - is all digits';
} else {
echo ' - is NOT all digits';
}
echo 'br /'.PHP_EOL;
}
returns...
asdf1234 - is NOT all digits
123.123 - is NOT all digits
123 - is all digits
http://www.php.net/manual/en/function.ctype-digit.php
An important note:
This function expects a string to be useful, so for example
passing in
an integer may not return the expected result. However, also note
that
HTML forms will result in numeric strings and not integers. See
also the
types section of the manual.

Integers can be negative too: I suspect your test would reject a
leading
'-'...
For my money, `is_numeric()` does just what I want.
The thing is, is_numeric() will not check if a string is a valid int,
but
any valid number, including a float.
For something like this, wouldn't a regex be better?
if(preg_match('/^\-?\d+$/', $string))
echo int
Thanks,
Ash
http://www.ashleysheridan.co.uk
That is so about is_numeric(), but once I know it's a numeric, coercing
it
to just an int is easy. *Validating*, rather than just assuring, that a
string is an integer is another matter; if you need to give feedback to
the
user, etc., in which case a Regex is better.
(One small nit, + is possible on integers, too.)
The op wasn't about casting a string to an int but detecting if a string
was just a string representation of an int. Hence using a regex to
determine that. Regular expressions are not just about giving feedback to
the user.
Guess regex are the only useful solution here. When you consider to use
built-in functions, just remember, that for example '0xAF' is an integer
too, but '42.00' isn't.

Hi Angela,
isset() will return false for an array key 'foo' mapped to a null value
whereas array_key_exists() will return true. The latter asks Is this key
in the array? whereas isset() adds and is its value not null? While
isset() is every-so-slightly faster, this should not be a concern. Use
whichever makes sense for the context here. Since you don't stick null
values into the array, I prefer the isset() form because the syntax reads
better to me.
Just a minor addition: Because 'null' is the representation of nothing
array_key_exists() and isset() can be treated as semantically equivalent.
Another approach (in my eyes the cleaner one ;)) is to simply _ensure_ that
the keys I want to use exists. Of course this only works in cases, where
the key is not dynamical, or the dynamic keys are known, which is not the
case here, it seems.
$defaults = array('stateNames' = array(), 'states' = array());
$values = array_merge($defaults, $values);
$values['states'] = array_merge(array_fill_keys($values['stateNames'],
null), $values['states']);

So in simple terms, just stick a ! (or the keyword not) in front of

if( not ( ($current_page == $saved_page) and ($current_ip ==
$saved_ip)
and ($current_dt ($saved_dt + 3600) ) ) {
Whilst this is true as far as it goes, I would suggest applying deMorgan's
laws
to simplify slightly to
if ( ($current_page != $saved_page) or ($current_ip != $saved_ip) or
($current_dt = ($saved_dt + 3600) ) )
If it is simpler depends, because
not ($everything $must $be $true)
is sometimes more logical :)
Also, the keyword versions of the Boolean operators are very low
priority, which is why you need all those extra parentheses -- if
you switch to the symbolic versions, you can leave all the internal
parentheses out to give:
if ($current_page != $saved_page || $current_ip != $saved_ip ||
$current_dt = $saved_dt + 3600)
Just to throw that in
if (array($current_page, $current_ip, $current_dt) != array($saved_page,
$saved_ip, $saved_dt + 3600))
This at least includes the information, that you have to sets of values,
that should be equal :)

I would only use this if you're planning to have servers all around the world in different timezones, then it would be easier to interchange data. Otherwise, stick with ur local timezone and it will save you a lot of unneeded timezone conversions probably. - Matijn This may be just me, but I've always preferred my servers, database, and such to run UTC, and let users select their own time zone they'd like to see. Well, imo it depends ;) There are cases, where it is interesting to know, when from the users point of view they have created the entity (like a blog post, a comment, or something like that). The TZ is part of the data and converting it silently to UTC is always data-loss. So in most cases it is OK, but not in every :) You can still convert from entity-TZ to UTC to user-TZ later. Its just one additional step. Regards, Sebastian -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- github.com/KingCrunch

Yes :) Because an operator = doesn't exists, thus the lexer will split

Re: [PHP] Very Large File Splatter
2013/2/22 Brian Smither bhsmit...@gmail.com PHP 5.4.4-TS-VC9 on Windows XP SP3 NTFS non-system drive with 18GB free. I dare not try to replicate this. As such, I cannot firmly place the blame on PHP. I have peppered a PHP application with a call to a function which appends-only to a logfile the parameters passed to it. Each pass of the application creates many MB of content. It is conceivable that I ran out of hard drive space. When that which what I was working on seemed to be acting very weird, I rebooted the computer only to see thousands of lines scroll by from Windows repairing the file system. I discovered logfile contents in many dozens of files. The timestamp and filesize of the damaged files were not changed. Only the contents replaced with slices of the logfile. Again, I'm not going to try to 'intentionally' replicate this, so I ask: Has PHP's interface with the NTFS file sub-system ever been reported to splatter a file across the contents of a drive? Is the PHP-interpreter even possible to create something like this? As far as I know PHP utilizes the common OS-syscalls to interact with the filesystem, so it doesn't interact with the harddrive directly, but online with the FS-driver. Did you shutdown the system cleanly, when you recognized this behaviour? If not, it would explain, that the windows assumes the filesystem must be repaired. I can imagine, that this repair process associated the broken data with the wrong file-entries in the fs-table, which could be an explanation for the behaviour you described.

Re: [PHP] Unset and __destruct
2012/12/6 Pierre du Plessis pie...@pcservice.co.za Hi all I searched the internet (probably not hard enough), and couldn't find a decent answer. I was wondering why, when calling unset on an object, it doesn't automatically call the __destruct method (if it exists) on the object. Thats because it was never intended :) The engine calls __destruct() right before the GC frees the object, but unset() only decrease the refcount. The next time the GC runs it will call the destructor and everythings fine When unsetting an object, php doesn't automatically remove references to other objects, and you need to manually call the __destruct method where you can remove any references to other objects. Why? When the GC removes the object from the memory (which might be slightly later) it also removes the references to associated objects and when their refcount reaches 0 they will get removed as well. Whats the problem? I know there is a lot of discussion around this topic, but couldn't find a definate answer as to why this isn't the default behaviour. Why should it? Thats the way a GC works :? Any clarification would greatly be appreciated. -- github.com/KingCrunch

orange.example.com), this should work:
?php

ini_set('session.cookie_domain','.example.com');
session_start();
$_SESSION['foo'] = 'bar';
session_write_close();

Then
?php

ini_set('session.cookie_domain','.example.com');
session_start();
echo isset($_SESSION['foo']) ? $_SESSION['foo'] : 'Session failed to

Would be better to put 'session.cookie_domain' into the php.ini. In both
cases: Clear cookies (at least for your site) completely and set

Split the data up into smaller pieces. There's rarely a valid reason to store a huge array of data as a single blob. It's an array, so it breaks up by the first level of keys at the very least. Look at APC, memcached, and redis. These are the most popular ways to store data in shared memory. Note that APC is a PHP extension so you can only access the shared memory from one machine, whereas memcached and redis are separate daemons so you can access them from multiple servers. Also, as Sebastian says, a database is another option unless you have a good reason to want the data in shared memory rather than a DB.

To answer Iñigo's comment - the OP's version is very much like an
If-ElseIF structure, and nothing like a Switch.
Just so. Perhaps those who are not grasping the point could re-read their
copy of The Elements of Programming Style by Kernighan and Plauger where
this sort of issue is covered.
See, it's all about expectations. When I worked at SLAC, there was a wise
guy there who had removed the catalytic converter from his Scirocco and who
though it clever to race up 280 from San Jose to SLAC at 100mph, sometimes
slipstreaming behind another idiot doing the same. If I look in my
rear-view mirror, I expect those I can see to be doing 70mph tops (that's
what a lot of people did 30 years ago on 280), not 100, and to make
judgements accordingly. Equally, I have certain expectations when I see a
switch statement; it trying hard to look like if-elseif-etc is not one of
them.
Just a minor rewrite of the original solution
switch (true) {
case $count = 7:
$boxes = 1;
break;
case $count = 14:
$boxes = 2;
break;
default:
$boxes = 3;
break;
}
Now -- the idea of switch as select on of some similar cases in mind:
Is this really breaking any expectation? I think this one is a valid
example, when switch(true) doesn't break the semantic of the
switch-statement.
And if this is already the end of expectations, then (sorry for that) the
expectations are maybe slightly limited :X I don't say please use
switch(true) wherever possible, but this one is nearly a prototype of a
valid use-case: You have several cases all depending on a single state (the
variable) and all of the same kind = constant.
Beside, because it is so extremely simple example, it can become even more
obvious
switch (true) {
case $count = 7: $boxes = 1; break;
case $count = 14: $boxes = 2; break;
default: $boxes = 3; break;
}
Guess some may argue about coding styles now, but thats not the questios
here (and anyway: Even coding styles could/should be broken, if it leads to
better code. Use it wisely ;)). And now: This _can_ break any expectation?
By the way, your car-expectation sounds dangerous...

IN your example, you are using a switch syntax that is nothing like

to do
with $count.
That `switch` is evaluating to true each case. It's an alternative of
using
if-elseif structure.
It may be an alternative, but it breaks the principle of least surprise.
If I'm looking through someone's code, and I see a switch, I expect to see
it used as Jim described. If the writer needs a different type of logic to
make a decision, that is what the cascaded if-elseif-elseif construct is
for, when the tests don't fall into a simple set-of-values choice.
But switch(true) is not a surprise by itself, it becomes to, when the
cases are surprising. And the given example directly fall into a simple
set-of-values choice, but the problem is, that switch(val) by design only
covers equality == and thats what this case is: A set like (1) between 1
and 7, (2) between 8 and 14, (Default) greater than 14. On the other side
a looong if-elseif*-else-chain is often more confusing and needs
refactoring anyway.
(Beside: Was the principle of least surprise not a ruby-thing? ;))
The job of a programmer is not to be clever with a view to impress those

making life easy for those who follow.
I don't see a problem in case ($count = 7) or case ($count = 14) or case

added to the use case in the future that doesn't fit the clever solution?
Like so often in our developers world many things breaks, when it comes to
new requirements.
Without knowing the intent of the code, it could be a headache to maintain.
Interesting, that you see 5 lines of code and assume, that nobody will ever
get the intent of this code ;) Of course the context is missing. I guess,
that $count is something like remaining days, or such, because 7 and
14 look like one week and two weeks, respectively. Thus I wouldn't
name the variable $count [1], but $remainingDays and voila: Context is
back and so is the intent :)
Of course the above code has a quite limited use-case, but that was the
requirement (for now, see KISS). If you need more, refactor/rewrite it.
[1] Even further: I was taught, that if I ever want to name a variable like
count, status, type, ... I should stop and probably don't use this
name. In most cases they are used wrong. This example here is quite good:
$count what?
Just my 2 cents.

Hello,
I was just wondering after writting the code in version 2 here below, it
turns
out in testing that it actually PHP is not validating the expressions

always I get the first case.
1.Using nested if statement {THE INTENDED BEHAVIOR}:
if ($count 14)
$boxes = 3;
elseif($count 7 $count = 14)
You don't need the count=14 part as you will *only* get there if
$count=14.
$boxes = 2;
else
$boxes = 1;
2. Using Switch {ALWAYS FIRST CASE!!!}
//$boxes = 1;
//switch ($count) {
//case ($count 14):
//$boxes = 3;
//break;
//case ($count 7 $count = 14):
//$boxes = 2;
//break;
//case ($count = 7):
//default :
//$boxes = 1;
//break;
//}
Does anyone know the answer why using the Switch it always execute the
first
case ?
As has been pointed out you need switch(true).
That's a strange way of writing a switch, IMO. You should be using the if
version.
Hi,
I've seen long discussions about this ;) I think this one is a example,
where 'switch(true)' is a legit expression, because switch-statements
define a construct, where the interpreter should select one of multiple
similar cases. This one seems legit, because they are very similar ;) It
says In case of $count look like X do this, or $count look like Y do that,
or $count look like Z do something else (and so on). For such I find the
if-elseif-elseif-elseif-elseif-else-construction quite confusing.
Beside this it can be rewritten as
switch ((int) (($count-1) / 7) {
case 0: // 1-7
case 1: // 8 - 14
default: // above 15
}

Re: [PHP] Re: PHP as Application Server
Hi, Once again I didn't read it completely (maybe I will do so), but my 2ct: I recently played with Ruby and Python and of course with their application server (at least a little bit). My experience was, that it is less fun as it sounds in the first place compared to a well designed webserver-interpreter-stack (and of course common OS-specific stuff for CLI). In my eyes it is good the way it is: Let PHP do it's job and let more intelligent tools do the other things, like spawning request-handling processes. Not saying, that I'm against an application, but I currently don't miss it :) On the other side someone must maintain it and someone must make sure, that it is secure and efficient. This resources should not taken from the core-team.

But, there seems to be some wrong information in your reply which

First of all, ip2long only returns negative numbers on 32bit systems,
not on 64bit (which most servers are nowadays).
Second, there's nothing wrong with the if, if(-5) is still true. The
only difference is that you can differentiate between IP 0.0.0.0 and
false. But IP 0.0.0.0 is not valid anyway.

I would actually suggest using inet_pton() instead of ip2long, since it
can also handle IPv6 adresses, not only v4 which people here seem to
think are the only ones in use on this planet. And I agree with Jim that
you really should use a strict equality check in this case.
IPv6 is a valid point, but inet_pton() triggers a warning in case of
invalid addresses, which makes it quite useless for validation in my
eyes. Also it's not available on windows before 5.3
And the strict comparison feels ... a little bit to much. Of course
depending on the use-case, I would treat 0.0.0.0 as invalid too.

Re: [PHP] Cost of redirect and site domain switch? Good Practice / Bad Practice / Terrible Practice
If you need to change the domain completely, choose 301. - Crawler will recognize it and will update their indexes quite soon. Especially you avoid duplicate content-punishments, because you say yourself, that the content originally comes from another domain, that isn't anymore (Like It's not a duplicate, it's _the_ content, but under a different address). - The delay is negliable. Also as soon as every index were updated no new visitor should enter your site via the old domain. Browser should (don't know wether they do, or not) recognize 301 too and redirect any further request to the url on their own (think of it as they cache the redirect permanently). If this change is only temporary I would recommend using 307 to avoid duplicate contents. I would even say, that a 307-redirect from somenewdomain.com to somedomain.com is more appropiate, but that depends.

Re: [PHP] Two ways to obtain an object property
Hi,
2012/8/15 phplist phpl...@myword.co.uk
This relates to a minor dilemma I come across from time and time, and I'm
looking for advice on pros and cons and best practice. Last night I
encountered it again.
Within a site I have a User object, and within page code would like to have
if ($crntUser-isASubscriber) {...}
There seems to be two ways to handle this:
I can have a User object method getSubscriberStatus() which sets
$this-isASubscriber. But to use this I would have to run the method just
before the if statement.
Or I could have a method isASubscriber() which returns the result,
meaning the if statement should be
if ($crntUser-isASubscriber()) {...}
or you just set User::$isASubscriber before.
or you can utilise __get()
I don't really get the problem. You can for example set the property right
after instanciation, or during instanciation (constructor).
$this-isASubscriber = !empty($subscriptions); // or something like that
Regards,
Sebastian
While this is last night's specific example, I seem to face the
method-setting-variable or the method-returning-result-**directly
decision quite often.
Is either of these approaches preferable, or does it simply not matter?

Sebastian I'm asking because what I have, which I think is the latest version of PEAR, is throwing numerous E_STRICT errors! Didn't you say you use the builtin packages from suse? I guess they are _not_ the latest :X I'm trying to establish if this is actually correct, and that PEAR has never been brought up to date, or I'm still hitting a pre E_STRICT version. As mentioned: That depends on the packages. There are packages, that are completely unmaintained nowadays. However, I have some tools, that relies on PEAR-packages and I've seen no E_STRICT for a while now, which makes me think, that at least some, if not all, are PHP5.4-compliant. I suspect the former which is not very helpful when I've been told simply to fix my own E_STRICT problems ... I don't have time to rework PEAR as well as the libraries I've already fixed :( So is E_STRICT simply something that should be thrown in the bin and the defaulting ON in PHP5.4 is somewhat premature? On my dev machine I use the same settings and it works well (I use Ubuntu, but I cannot imagine, that this makes such a huge difference). Did you try this in the meantime?

[PHP] Bazar behavior w/ private member variables

Subject: Re: [PHP] Bazar behavior w/ private member variables

Hi,
Private properties are only accessable from within an object of the class,
where it's defined. If you define a new private property with the same name
in a subclass, then you just have two properties with the same name, but in
different classes. They are separate from each other ;) It seems, that you
are _really_ looking for protected properties instead.

Sebastian

Hi all,
Strangely PHP seems to let each class have its own layer of private
scope
for member variables. If a subclass defines a member variable of the
same
name as one defined in the parent the values are maintained
independently
in instances of the child class.
First off a simple class with a private member variable $_myPrivate,
and a
public accessor method which returns its value:
class A
{
private $_myPrivate = 5;
public function getMyPrivate()
{
return $this-_myPrivate;
}
}
Second, a subclass, that gets weird right away, first we define a
private
member variable that already has been defined in the parent class, and
give
it a different initial value. To illustrate the behavior we have two
accessor methods, setMyPrivate that uses the $this keyword to get the
value
of $_myPrivate, which returns the value of the subclasse's version of
the
variable, and getParentsMyPrivate, that calls A::getMyPrivate via the
parent keyword and it returns the value of $_myPrivate as defined in
the
base class.
class B extends A
{
private $_myPrivate = 6;
public function setMyPrivate()
{
$this-_myPrivate = 6;
}
public function getMyPrivate()
{
return $this-_myPrivate;
}
public function getParentsMyPrivate()
{
return parent::getMyPrivate();
}
}
Look at a var_dump of an instance of B:
object(B)#2 (2) {
[_myPrivate:B:private]=
int(6)
[_myPrivate:A:private]=
int(5)
}
clearly storage is allocated for two different values. Now I'm sure
you
all know that if I were to define a private method in A and try to
call
it
from B a Fatal error is raised, something on the order of
PHP Fatal error: Call to private method A::tryToCallMeFromB() from
context
'B'
so why the special treatment for member variables, is this supposed to
be a
feature?
-nathan
That is OOP accross all languages. If you want the child class to
modify the variable, then set it to protected. Private is only
accessible within that class.
I know that sounds like it should make sense but if it's true, it's an
aspect I've never known about, at least maybe I'm just spacing really bad
or something...
Anyway, this chokes in javac:
public class PrivateAccess
{
private Boolean isAccessible = true;
}
class PrivateAccessChild extends PrivateAccess
{
public Boolean getAccessible()
{
return isAccessible;
}
}
PrivateAccessChild.java:5: isAccessible has private access in
PrivateAccess
return isAccessible;
^
-nathan
Ahhh, but if I add the private declaration in the subclass it works. Where
have I been??

Back in the day when we didn't have nifty gui screens and an 24 line terminals (yay green on black!), if a function exceeded one printed page, it was deemed too long and marked for refactoring. I think the idea of setting an arbitrary limit on the number of lines that a function should contain is quite ludicrous and something which I will completely ignore. If a function requires a hundred or more lines then so be it. The only reason to take a block of code and put it into its own function is when that code is likely to be called more than once so that it conforms to the DRY principle. If it is only ever used in one place then there is no point. The problems I have with creating lots of small used-only-once functions is as follows: - you have to create a meaningful name for each function. - all those functions should be arranged in alphabetical order within their containing file - having them in a random sequence makes it difficult to find the one you want. snip And yeah, alphabetical order? Really? This is a throwback to my 3GL days when all components within a file were arranged in alphabetical sequence so that they were easier to find when you looked at the printed listing. Group them by similarity, sure. But today, with IDEs that will jump straight to functions and class methods, and the good ol' find tool on every editor I've ever seen, is sorting them alphabetically really necessary? Seems like a waste of time that is likely not going to be done by fellow developers working on the same codebase. I have never come across an IDE that jumps to a function when you click on its name, so how does it return to where you jumped from? At least PhpStorm and Eclipse have a feature to return where you come from. I haven't seen an IDE, that is _not_ able to jump to a functions or methods source for a long time now. Rather than artificially reduce the size of a function to satisfy someone else's limited attention span I would rather use the scroll wheel on my mouse. Scrolling up or down within a single function is easier than searching/finding/jumping to a series of sub-functions which may exist at random locations within the same file. If the functions were named properly you don't have to follow every execution path to the deepest deep. Or do you reading PHPs C-source, just because a wild substr() appeared? When you see a method loadFromFile() and the IDE tells you, that it expects a $filename as parameter, why should you jump there just to make sure, that the method loads something from a file by the filename given as first parameter? I will only split a large function into sub-functions when it makes sense to do so, and not because some nerd cannot scan more than 20 lines at a time. The question I ask myself is: Why ^should^ a scan more than 20 lines at a time, if it is possible, to make it clearer, but another nerd decided, that it is too much work (or whatever). Maybe it's may attention span, but I'm usually slightly bugged, when I have to read code monsters. Compared to a book it's a kind of One chapter in a single sentence.
