On my local machine here PHP does not output the shebang line. AFAIK
it detects and strips it at the compilation phase. Have you tried it?
Hang on, ignore that. You're including the file, not running it on the CLI.
What do you mean when you say it doesn't work? Do you mean you get no
output?
I mean that the shebang line at the top of the included file is output
to stdout even when I turn on output buffering on prior to including the file.
nothing else is output but that's because the script doesn't generate any
further
output - it logs everything instead - and I know it runs because the relevant
lines
appear in the relevant log file.
I suggest you remove the @ at the start of the include while developing
it. Or alternatively spit something out after you call ob_end_clean so
you know it couldn't include the file.
the @ is niether here nor there with regard to the problem I have, well more
of an annoyance - nobody is going get hurt by some spurious output to stdout but
it looks messy.
just to clarify - I need to be able to run the script directly (as an
executable) and
be able to include it within another script ... so the shebang line is needed
(well I could hack around it with a wrapper script to use directly on the
command line
or run it using /usr/bin/php foo.php ... but I don't find either of those
satisfactory)

This works...
indeed ... I tested it and it works on my server too. my code is no different
to yours with regard to the context of the problem. so what's going on.
I think (I know) I forgot to mention one tiny little detail.
the whole 'include' code occurs in a script that forks itself ...
the script forks itself a number of times and each child then performs
the include.
so I tested the fork issue with your script ... it still bloody works,
(see the for loop below) so it's something else ... I thought it might
be the difference between using ob_get_clean() and
ob_get_contents()+ob_end_clean()
but that doesn't seem to be it either.
the worse thing is my script has just stopped outputting the shebang lines of
the included script(s) ... oh well ... the problem is solved, dunno how, dunno
why,

it's sick, I like it, nice example of streams filtering while your at it.
I learned something! it also works in so far that the shebang line is no longer
output but the output buffering in *my* script(s) doesn't work, whilst the same
construction does work in Stut's test scripts (although whilst playing with
his script I did manage to bork ik so that the output buffering *doesn't* work
there anymore ... how I did that I can't fathom)
anyway - they problem has been nicely shoved under the carpet. apart from
the shebang lines the script don't ever output anything anyway but rather
log to files ... a simple redirect output to /dev/null in the command line
that is used to run the 'master' script will take care of any spurious cruft
ending up on screen.

Re: [PHP] Start/stop daemon using php
David Sveningsson schreef: Hi, I've written an application in c which I would like to start/stop as a daemon in gnu/linux. The application has the argument --daemon which forks the process and exits the parent. Then it setups a SIGQUIT signal handler to properly cleanup and terminate. It also maintains a lockfile (with the pid) so only one instance is allowed. So, to start this application I created a php site that calls exec(/path/to/binary --daemon /dev/null 2 /dev/null). Everything is working so far, but I cannot get the application to receive the SIGQUIT when I start using php and exec. Not even manually using kill in the shell. It works correctly if I start manually thought. So, is this possible to do? Doesn't exec allow applications with signal handlers? Is there some other way to terminate the application? there is nothing special about exec that makes working with the kill command different to anything else, though you might take a look at the posix_kill() command instead. e.g. posix_kill(`cat /path/to/pidfile`, SIGQUIT); you say you can't even send SIGQUIT to the daemon using kill on the command line, this suggests the problem lies in the fact that the daemon's signal handler is not actually working (when the process is daemonized). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

PHP and web application development are kind of a new bag for me and I'm still trying to get my bearings. I see that designing a web application can involve all of the following: html, javascript, php, sql, ajax, xml, design patterns, and other things. Its kind of... information overload right now? For what I want to do I know I'm going to need to learn all of them, but coming up with a roadmap for what should I learn first? is becoming problematic. I want to start working on projects but I'm just not sure what order to learn things in. I don't want to come up with something that works, and then have to re-write it all over again simply because I read a new chapter in a new book. I would just like some advice on what order to go about this stuff. Thanks! HTML, xHTML, XML - the basics of this are simple enough - the intricasies will show their ugly head as time goes by. outputting something that a browser will grok is a piece of cake, in time you'll get the hang of generating output that's 100% valid :-) javascript - learn as you go, start with cut and paste solutions and work up from there as required, plenty of people never bother with javascript at all for accessibility reasons. basically anything you want to make dynamic (singing and dancing) on the clientside (i.e. in the browser) will require javascript (okay so there is Java and Flash also buts that's beside the point) AJAX (or AJAS ;-) in our neck of the woods) is basically the use of javascript to run HTTP requests 'in the background' of a page, i.e. grabbing/sending some data from the server without refreshing the page (and then presumably manipulating the existing page based on the results of said background request ... AJAX can get fairly advanced and I think you'll know when you actually need it. Design Patterns (there is another current thread about this) - basically it comes down to applying known concepts/paradigms/strategies to solve a problem ... patterns apply to all walk of programming life ... my guess is you've 'used' them plenty in other languages even though you may not have recognized them as such ... writing clear and maintainable code is probably the best pattern to apply to development ;-) PHP, the king of web-development languages, *this is the place to start* if your interested in server-side coding (you could specialize in client-side stuff only - there are plenty that do). SQL, very shortly after your first php script is up and running you'll be wanting to store stuff in a database - SQL is the means to manipulate the data ... learning SQL, especially the mySQL variant, will come naturally when you dive into php because the practical ties between the 2 are so strong ... what's a dynamic website with out persistent, changeable data? rewrite stuff? yes you will, garanteed, many times over. this doesn't ever stop :-) apart from the odd occasion when you throw something away and forget it ;-) you could consider using perl instead of php ... perl's write-only nature would admonish you from any rewriting responsibilities :-P so basically? start writing some crufty php ... find yourself diving into HTML and SQL before you know it and then rewrite the cruft as and when new understanding presents itself :-) it's the road most of us walked (except for Tedd, he programmed the Rocks[tm] used to build the road) -Matthew -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

that's just string generation ... 'style' equates to harassing people

recommended: phpmailer (google it)
which you can then pull apart to see exactly how it works (it's work
comprises of building the $message into a format that mail readers will
understand as multi-part mime.)
mail('[EMAIL PROTECTED]' , 'An Event' , $message);
If so, how do you style it?
If not, how do you send stylized email?
style comes naturally to some of us ;-)

[PHP] Re: [PHP-DEV] string operators for assigning class constants
this is a php generals type of question.
Sebastian schreef:
hi,
why isn't it possible to assign class constants like this:
class test
{
const
DIR='dirname'.DIRECTORY_SEPARATOR.'anotherdirname'.DIRECTORY_SEPARATOR;
}
is there some performance issue?
classes are defined at compile time, so are their const declarations - it's
not possible to evaluate an expression at compile time.
with define('FOO', 'bar'.QUX); you can do it because the define occurs at run
time.
anyone ever tried this or was there a discussion about it? i would find this
very useful.
find another way to do 'it' :-)

**
And I've tried troubleshooting for a while; I'm pretty sure I'm opening the

functions like fgets to work.
you pretty sure? your code doesn't check that the file handle is valid.
Here is my code if you're interested (it's so that I color every 2nd line in
the text):
*$boardFile = MessageBoard.txt;
do you know what the current working directory is? my guess
is that whatever it is the text file is not in that directory.
try setting an absolute path to the text file e.g.
$boardFile = /path/to/my/MessageBoard.txt;
and then do something like ...
$boardFileHandle = fopen($boardFile,r);
if (!$boardFileHandle)
die ('no messages, or something equally annoying!');
for ($counter = 1; !feof($boardFileHandle); $counter += 1) {
$colorLine = fgets(boardFilehandle);

chances are you want to use a private instance property:

}
$a = new Foo;
$b = new Foo;

$a-bar();
$b-bar();
$b-bar();

Pauau,
Please visit the link below for help..
http://www.php.net/manual/en/language.oop5.static.php
what you are using is potentially not what you think it is. you are using
a 'static variable' which is not a static class member.
actually it pretty much *is* the same - the static class member will exhibit the
same behaviour, only the scope is different.
you can find the
doc on static variables here,
http://www.php.net/manual/en/language.variables.scope.php
im not sure if their behavior is well defined when they are used in classes,
or objects.
behaviour is indentical to usage inside standalone functions.
as Nirmalya, has alluded, you should check out the docs on static class
members. im sure that you can achieve whatever you need to by using
some combination of static class members and instance variables.

Any clues or right direction would be awesome.
First of all, don't do that. :-)
Instead, set up a job system of what should be copied/tarred, and
then notify the user via email.
Don't make the user sit there waiting for the computer!

I was actually doing what you just gave the code for. As of now, I was
doing something like:
for file in files:
copy from source to folder
echo Copying files encapsulated in ob_flush()
tar the file which hardly takes time on the filessyetm but does take some time
Provide the link to the tar
So at the client side it was like:
Copying file #1
Copying file #2
Download link
I though I could apply some funkiness to it by using some AJAX based
progress bar for which the example showed some sort of hooking and all
which I thought was too much for such a job. I will talk to my boss
regarding this and do the necessary.
BTW, whats the issue with AJAX based approach? Any particular reason
other then it seems to be a hack rather then an elegant solution
(which is more then enough reason not to implement it...but I wonder
if there is a technical reason to it too)?
the problem with the AJAX approach is the fact that there is absolutely
no reason for a user to sit staring at the screen. hit 'Go' get an
email when it's done, do something else in the mean time.
of course a PHB might demand functionality that gives him/her an excuse to
watch a progress bar ... in which case why not waste man hours making it a
funky web2.0 deal ... heck go the whole hog and use 'comet technique' to
push update info to the browser.

For those of you who want to know what I'm doing with the solution,
please review:
http://www.webbytedd.com//var-string/index.php
Warning: Geek meters should be worn at all times and exposure should
be limited. All code is shown.
The problem that I was seeking a solution for was simply an easier
way to grab POST and GET variables and place them into SESSIONs while
keeping the most current values current.
I'm a little disappointed in the solution because I wanted the
statements to be:
$post_var = sessionize_post($post_var);
$get_var = sessionize_get($ger_var);
But, the function provided by Daniel (and found in the literature)
would not work from within my session_post and session_get functions
-- I think it's probably something to do with the scope of the
variable.
In any event, I had to alter the calls to:
$post_var = @sessionize_post($post_var, vname($post_var));
$get_var = @sessionize_get($get_var, vname($get_var));
I don't see why this has to be so convoluted - it would be a heck of
a lot easier to do it with a string:
$post_var = @sessionize_post('post_var');
so why exactly is that not an option (or good idea)?
You see, there can be reasons why someone would want to know the
variable's name.

Re: [PHP] PHP CLI Problem
Robbert van Andel schreef: I am having trouble with a PHP CLI script I wrote to help manage my website. The site is on a shared hosting server where the PHP installation is set up as a CGI. The script creates some backups of my databases and sends them to Amazon's S3 service. First off, the script runs great from the command line when I type php5 backup.php but when I type ./backup.php I get an error: bash: ./backup.php: No such file or directory. is the script marked as executable? I thought maybe this is a problem with the top declaration in the script #!/usr/local/bin/php5. The problem is that it appears the server has several php5s I can reference /usr/local/apache/share/cgi-bin/php5 /usr/local/bin/php5 to determine which php5 you are using type: $ which php5 this gives you the full path, which you will need to use in the relevant cron line (and/or the shebang line at the top of the script) - cron requires fullpaths. But it doesn't matter which one I put at the top of the script, I get the same error. Okay, so I can live with having to type php5 backup.php. However, when I try to make a cron job from the script, the script never runs. The crontab entry looks like this 1 0 * * 2 php5 /kunden/homepages/23/d117947228/htdocs/oregonswimming/administration/backup/ backup.php backup.log I know the backup never runs because I redirect the output to a file and have an email sent to me upon conclusion of the script. The log file doesn't show anything nor do I ever receive an email. My web host will not provide any support for scripting, so I'm hoping someone here can help. Questions: * How do I determine what to put at the top of the script so that I can just call backup.php? * What, if anything, do I need to do to make the script work from cron? I've seen some comments on the web regarding PHP CLI when PHP is a CGI, but none of them seem to apply to me. Thank you in advance for your help.

php should handle the conversion internally for you.
if you want to type cast a value to a string, simply do

I believe this is the difference with arrays:
$a = array(2 = foo);
Array(0 = null, 1 = null, 2 = foo)
$a = array(2 = foo);
Array(2 = foo)
not true:
alice:~ jochem$ php -r '
$a = array(2 = foo); $b = array(2 = foo); var_dump($a, $b);'
array(1) {
[2]=
string(3) foo
}
array(1) {
[2]=
string(3) foo
}
php treats anything that is the string equivelant of an integer as an integer
when
it comes to array keys - which comes down to the fact that you cannot therefore
use
a string version of an integer as an associative key.
so $a[2] and $a[2] are always the same element.
the same is not exactly true for floats - although you can use them as array
keys you'll
notice in the output of code below that they are stripped of their decimal part
(essentially
a floor() seems to be performed on the float value. I have no idea whether this
is intentional,
and whether you can therefore rely on this behaviour:

$a = array(2.5 = foo); $b = array(2.5 = foo); var_dump($a, $b);'
array(1) {

I'm in the market for a new framework, but please only tell me about ZF because I don't want to spend my own time researching stuff for myself. you need some glasses? I've just spent 4 hours reading ZF documentation and code ... today - I've played with it in the past but it was still beta at that time. I'm starting to take another look, but no ammount of playing with it or reading documentation will tell me if I'm going to have major regrets about choosing ZF for a large project when I'm 400 hours into it and stuck with a deadline and an impossible situation. funnily enough I'm not capable of researching inside someone else's head when it comes to *their opinion*, more specifically people who you are familiar with to soome degree, whereby you able to gauge to a better extent how relevant the opinion/experience offered is to one's own situation. Since when is learning something new a crime? and where do you go to learn someone else's opinion? Why are you even a programmer? something bothering you? got out of the wrong side of bed today?

I wish I knew which version we were running before that - but that record was not kept. I guess we are stuck with this, what maybe is a problem with this version, until the Redhat RPM gets higher than 4.3.9 - since that is what our server manager uses for updates I could always adjust it to be: date(m/d/Y,strtotime(+ .(6-date(w)). days)); That should always return the next Saturday of the week, and if I am correct in my thinking, then even on the Saturday, 6-6 = 0 - which would return that day...

They're boring and tired and serve no purpose. IE6 is fast and launches in 1 second. FF takes many seconds. IE7 is also a bloated pig and I will be very sad in 15 days when M$ FORCES everyone to it. IE also has very nice DirectX rendering filters for gradients. or maybe rebuild the windows machine in question (hey it wouldn't be the first time something like this was helped by a clean install right?) It is NOT the OS. It is the PEAR site itself that is to blame. There is clearly some code or tag or something that is causing this failure. let's see now - a webserver outputs some content, it may be invalid. a browser crashes upon trying to render the content. hmm, sounds to me like the problem is in the browser, decent software should crash because of shitty input. granted if the PEAR just didn't render properly or caused 'invalid XML/XHTML/whatever' message in the browser then yes it would be the site's problem. but until the browser is capable of saying 'hey this content is junk, I can't use it [because of XYZ]' then really the first issue is with that browser. it's same at the server end - if your browser (or you, maliciously) posts freaking/invalid byte sequences at some script I've got on the server then would you consider it correct that the server crashed? or would you expect some kind of 'your input sucks' error message to appear? It didn't used to be there either. I've gone to the PEAR site many times in the past. The site isn't even that compex, so I'm curious why the webmaster couldn't just fix this problem and make everyone happy? we work around bugs and problems all day in the job we do - how is cranking up a different browser because a site happens not to work with a particular site any different? if we're really about making everyone happy - how about we tackle something serious like the whole 'war for oil' business? exactly how fragile is a human mind if a browser crashing on a particular site is deciding factor in being capable of experiencing happiness?

the 'or die(bla bla);' type of error handling is rubbish, you can
use it for simple/throw-away scripts but when your writing a class

far larger than it needs to be, which IMHO is an unnecessary waste of

lost you on this part ..
whether you create an instance in client code by calling new or
encapsulate the call
to new in a simple factory method there will still be only one
instance of the class,
and it will still be in scope once the method is finished executing,
because all it does
is return an instance of the class its a member of.
maybe you mean something other than what i posted earlier when you say
static method?
You posted a singleton pattern.
huh? the OPs getInstance() method returns a new object on each call, hardly
a singleton is it?
That means that from the moment you call
the static method until the end of the script that object exists. That's
probably fine for web-based scripts that don't run for long, but I live
in a world where classes often get used in unexpected ways so I tend to
write code that's efficient without relying on the environment it's
running in to clean it up.
are you saying that the OPs getInstance() method causes each new instance
to hang around inside memory because php doesn't know that it's no longer
referenced,
even when it's used like so:
Test::getInstance()-doSomething();
and that your alternative does allow php to clean up the memory?
This was your code...
?php
class Test {
public static function getInstance() {
return new Test();
}
public function doSomething() {
echo __METHOD__ . PHP_EOL;
}
}
Test::getInstance()-doSomething();
?
This would be my implementation...
?php
class Test {
public static function doSomething() {
$o = new Test();
$o-_doSomething();
}
protected function _doSomething() {
// I'm assuming this method is fairly complex, and involves
// more than just this method, otherwise there is no point
// in creating an instance of the class, just use a static
// method.
}
}
Test::doSomething();
?
Of course this is just based on what the OP said they wanted to do. If
there is no reason to create an instance of the object then don't do it.
It's fairly likely that I'd actually just use a static method here, but
it depends on what it's actually doing.
But as I said earlier, each to their own.

IIUC the yet to be released garbage collection improvements will potentially find/destroy unused zvals sooner (as well as being better in sorting out defunct circular references etc) but that the garbage collection itself uses a certain ammount of cpu cycles and in short running scripts (e.g. most of what we write for the web) it's likely to be better to let php just destroy memory at the end of the request. that said your more cautious approach cannot hurt :-) PS - my apologies if the memory related terminology I've used is somewhat bogus - please put it down to my lack of proper understanding :-/ -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

im pretty sure constructors return an object instance:
php class Test { function __construct() {} }
php var_dump(new Test());
object(Test)#1 (0) {
}
AFAIK, constructor simply constructs the object,
and *new* is the one that binds the reference to the variable
on the lhs.
not exactly - 'new' asks php to initialize an object of the given class,
the 'binding' to a variable occurs because of the assignment operator. the
__construct()
method is called automatically by php after the object structure has been
initialized, so primarily
nothing is returned because the call to __construct() doesn't happen directly
in userland code.
at least that's how I understand it.
So, constructors return nothing.
but anyway, how could you even test that __construct() returned void
and the new keyword returned a copy of the object? new essentially
invokes __construct() and passes along its return value, near as i can
tell.
Christoph,
if you dont want to write a function in the global namespace, as
suggested
in the article, Eric posted, just add a simple factory method in your
class,
eg.
?php
class Test {
public static function getInstance() {
return new Test();
}
public function doSomething() {
echo __METHOD__ . PHP_EOL;
}
}
Test::getInstance()-doSomething();

you may wish to return object clones to chain with as opposed to
the same object - the example below is fairly bogus but it
mgiht be helpful to you (btw run the code to see what it actually
does as opposed to what you think it should do ... hey it caught

the above is plain wrong.
1. you can't do multiple property definitions for a single [array] property
2. your storing hardcoded values in a class which is meant to be somewhat
generic/reusable
3. you've just told the world your password/login/db credentials
public __construct() {

}
constructors aren't meant to return anything. besides you won't be able to
retrieve the returned value.
not too mention '$this-$connInfo' is the wrong syntax it should be:
$this-connInfo
I'd recommend some more research on basic class syntax.

letters
followed by a digit followed by anything.
$var = do_something(,,a2b3cd5ef6ghi7232jklmn);

is an internal interface (part of the zend engine), so i thought to
myself, perhaps only internal interfaces can be extended, but
then a quick test proved my suspicions wrong. in fact, interfaces
can even extend multiple parent interfaces, just like java (*ducks*).
here is the sample code so you can see for yourself:

interface Crazyfiable {
public function getCrazy();

interface Extendable extends Somethingable, Crazyfiable {

public function extend() {
echo 'i extended something..' . PHP_EOL;
}
public function getCrazy() {
echo 'im a crazy bastard now!' . PHP_EOL;
}
}
/*

$sc = new SuperClass();
$sc-doSomething();
$sc-extend();

as an aside, I often use php -r to test snippets like this e.g.:
$ php -r 'echo foo!;'
very handy and saves having to create a file everytime you test something,
it does mean your forced to use double quotes only in the code (otherwise

Plus I enjoy all the people complaining about how users shouldn't change the subject. The gmail thread grouping takes care of all that for me. :D The only real downside is you can't view the raw source of messages or get the headers. At the top-right of each message is a little downward-pointing arrow (next to the Reply button). Click that, and then you click Show Original to view all of the headers. I actually don't see the same threading in Gmail. If a subject is changed, for whatever reason, my Gmail sees it as a new thread - even just with `Re:` appended to it. No clue why. -- /Dan Daniel P.

I am completely stumped. tia I just spotted this in the manual page for date_create: When using these functions inside of destructors or functions called as a result of being registered with register_shutdown_handler, be sure to use date_create() instead of new DateTime(). This is because new DateTime will throw an exception on failure, which is not permitted in any of the above circumstances. If new DateTime() does fail in one of these circumstances, you will get an error stating Fatal error: Exception thrown without a stack frame in Unknown on line 0. Maybe there's a clue for you in there? oh boy do I feel stupid. and I knew about this, it just didn't spring to mind. thanks for doing my thinking for me ;-) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: how dod you get to do multiple mysql queries concurrently?
Per Jessen schreef: Floor Terra wrote: I know how to do multiple queries - the key issue in my question was how to do them concurrently (i.e. in parallel). So you want to make PHP multithreaded??? No, just the mysql queries. Try pcntl_fork() to create a child process for each query. Each child can make it's own MySQL connection. Hmm, interesting idea. I wonder if that'll work under apache? you'll end up forking a complete apache process - assuming mod_php. you don't want that. but then I don't think you want 30+ second queries being run via apache at all :-) /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I understand what this means but not how it can happen given the following: I wonder if you can wrap a try/catch around the loading of the constants and class definitions? you can, I do, but it does really do anything - an exception is only ever thrown in userland code and a few specific extensions (none of which Im using) the problem was in a DB query related exception that was being thrown (sometimes) in a piece of code the was being conditionally setup as via register_shutdown_function(). I totally forgot about the shutdown exception to exception throwing :-P thanks to Peter Ford for putting me straight Or you already did that and it didn't work? There was something on internals@ yesterday about fixing some kind of backtrace thingie where this could happen, but I think it was more about having such a large backtrace that half of it was off in a different RAM segment or somesuch... Anyway, for future reference for somebody else who ends up here, that may also be worth checking out, even if Jochem has found and fixed his issue. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
