It does not reference a function, so I found it odd. It did give a line to
a function with array_merge on it.
Has anyone seen this in the apache error logs? We are using PHP 5.3.3.
Show us the line, and a few lines around it.
public static function getInfo($params = array())
{
$results = array();
$url = 'http://google.com';
$props = array
(
'key'= Yii::app()-params['param1'],
's'= Yii::app()-params['param2']
);
if (!empty($params))
{
$props = array_merge($props, $params);
$url = $url . http_build_query($props, '', '/');
It may be possible that params has unsafe data in it. The previous dev did
not validate the data passed in via get.
The code populating params looks like:
$params = array
(
'd' = $_GET['d'],
);
$job = Job::getInfo($params);
My best guess is that either $props or $params contain a function reference or
similar construct. Examine their contents with var_dump.
As a check you could expand out the effect of array_merge and see if you still
get the same with a PHP implementation.

It's possible to set things up in a different way (using FilesMatch instead of AddHandler) to avoid this particular problem, but that breaks other things, so there's no perfect solution. More generally, the real problem is that scripts are looking at the final extension of uploaded files to decide whether they're safe or not, which is dangerous. They're simply assuming that a .gif file can't run a PHP interpreter, for example... which is usually true, but certainly not always: some people run all their files through PHP. ---END QUOTE--- This is somewhat daft. Yes, Apache offers this feature, but you don't need to configure it to work will all extensions. I'd be curious to know what their issue is with using FilesMatch, since that provides a way to disable this behaviour. And, honestly, who would have a PHP file per language? I think it's perfectly reasonable to not allow that, because duplicating PHP code across many files is an incredible stupid way to support multiple languages. Some people run all their files through PHP - true, but that doesn't mean they should, or that you, as a responsible web host, should be endorsing it. The problem is the weak PHP upload mechanism! As workaround my service provider tries to block suspicious filenames, but the PHP developpers themself should work on this severe security problem. PHP developers should absolutely validate all content coming in from users in every possible way, but I would be highly dubious about trusting a host who gives the reason above for what I consider a lax and insecure Apache configuration.

Easy test: create a file in a text editor containing some PHP (?php phpinfo();

test.pgif. Then hit http://www.yourdomain.com/test.pgif in your browser. If you

Re: [PHP] refernces, arrays, and why does it take up so much memory?
On 3 Sep 2013, at 02:30, Daevid Vincent dae...@daevid.com wrote:
I'm confused on how a reference works I think.
I have a DB result set in an array I'm looping over. All I simply want to do
is make the array key the id of the result set row.
This is the basic gist of it:
private function _normalize_result_set()
{
foreach($this-tmp_results as $k = $v)
{
$id = $v['id'];
$new_tmp_results[$id] = $v; //2013-08-29 [dv] using a
reference here cuts the memory usage in half!
You are assigning a reference to $v. In the next iteration of the loop, $v will
be pointing at the next item in the array, as will the reference you're storing
here. With this code I'd expect $new_tmp_results to be an array where the keys
(i.e. the IDs) are correct, but the data in each item matches the data in the
last item from the original array, which appears to be what you describe.
unset($this-tmp_results[$k]);
Doing this for every loop is likely very inefficient. I don't know how the
inner workings of PHP process something like this, but I wouldn't be surprised
if it's allocating a new chunk of memory for a version of the array without
this element. You may find it better to not unset anything until the loop has
finished, at which point you can just unset($this-tmp_results).
/*
if ($i++ % 1000 == 0)
{
gc_enable(); // Enable Garbage Collector
var_dump(gc_enabled()); // true
var_dump(gc_collect_cycles()); // # of elements
cleaned up
gc_disable(); // Disable Garbage Collector
}
*/
}
$this-tmp_results = $new_tmp_results;
//var_dump($this-tmp_results); exit;
unset($new_tmp_results);
}
Try this:
private function _normalize_result_set()
{
// Initialise the temporary variable.
$new_tmp_results = array();
// Loop around just the keys in the array.
foreach (array_keys($this-tmp_results) as $k)
{
// Store the item in the temporary array with the ID as the key.
// Note no pointless variable for the ID, and no use of !
$new_tmp_results[$this-tmp_results[$k]['id']] = $this-tmp_results[$k];
}
// Assign the temporary variable to the original variable.
$this-tmp_results = $new_tmp_results;
}
I'd appreciate it if you could plug this in and see what your memory usage
reports say. In most cases, trying to control the garbage collection through
the use of references is the worst way to go about optimising your code. In my
code above I'm relying on PHPs copy-on-write feature where data is only
duplicated when assigned if it changes. No unsets, just using scope to mark a
variable as able to be cleaned up.
Where is this result set coming from? You'd save yourself a lot of memory/time
by putting the data in to this format when you read it from the source. For
example, if reading it from MySQL, $this-tmp_results[$row['id']] = $row when
looping around the result set.
Also, is there any reason why you need to process this full set of data in one
go? Can you not break it up in to smaller pieces that won't put as much strain
on resources?

Can someone explain to me why this doesn't suffice? The signon process expects them to be there, so when they are not (after the 'unset'), how come my signon process still detects them and their values? The global variables you're referring to are just that, global variables; changing them will have no effect on the browser. Basic Auth was not designed to allow users to log out, but you can make it happen with some Javascript. Have your log out link call a Javascript function which sends an XMLHttpRequest with an invalid username and password. The server will return a 401 which you ignore and then take the user to whatever URL you want them to see after they log off. Not pretty, but it works. -Stuart Thanks for the timely response! Before I try your suggestion - one question. Since when is a global variable not changeable? Doesn't the fact that it reflects a modified value when I do change it tell me it worked? I change the value to 'xxx' and show it having that value, but when the script is called again the old value appears. Very confusing! I didn't say you couldn't change it, I said doing so will have no effect on the browser. It's not really confusing so long as you understand how PHP works. Each request is brand new - nothing is retained from previous requests. The two variable you're changing are set by PHP when the request comes in from the browser. The fact you changed them in a previous request is irrelevant because 1) that change was not communicated to the browser in any way, and 2) PHP doesn't retain any data between requests [1]. If you've been coding assuming that changes you make to global variables are retained between requests you must have been having some pretty frustrating times! -Stuart [1] The one exception to this is $_SESSION, but it's important to know how that works. The $_SESSION array is populated when you call session_start(). It's loaded from some form of storage (files by default) and unserialised in to $_SESSION. When the session is closed, either implicitly by the request ending or by a call to one of the methods that explicitly do it, the contents are serialised to the storage system. Once closed, any changes to $_SESSION will not be stored; it becomes just another superglobal (not that it was ever anything else). -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You don't need to do anything on the server-side. You simply need a JS function
that sends a request to a URL that requires basic auth, with an Authenticate
header that contains an invalid username and password. Then, when your server
responds with a 401 Authentication required (which it should already do for an
invalid request) you can set location.href to whatever URL you want the logged
out user to see.
If you don't know how to make a request from Javascript -- commonly known as an
AJAX request -- then google for it. I'd recommend the jquery library if you
want a very easy way to do it.

It's not the basic auth that I'm having the issue with - it's the 'header'
thing and understanding what a 401 is doing and how I'm to ignore it. Never
had to play with these things before and this part is all new. Let's face it
- I'm an applications guy, not a systems guy. All this talk of headers and
such is greek to me.
HTTP headers are as important for application guys as they are for systems
guys. I appreciate that this may be new to you, but it's pretty basic knowledge
about how HTTP works.
Basic auth is simple, and you need to understand how it works to understand
what I've been trying to say. Here's how HTTP auth works:
1) Browser hits page.
2) The PHP script knows this page requires HTTP Auth, checks the
PHP_AUTH_[USER|PW] variables but doesn't find anything, so it responds with an
HTTP status of 401 Unauthorised.
3) The browser gets the 401 response and displays the login box.
4) User enters username and password

On 20 Aug 2013, at 21:08, Sebastian Krebs krebs@gmail.com wrote: 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. The language and the 'link between the language and the network' are two completely separate things. The link, as you put it, is the web server. A web server doesn't need to do anything more than set up environment variables and run an executable, and even setting up the environment is technically optional. BASH can build web pages. I wouldn't recommend using BASH, but there's nothing technically preventing it. Node.js is not the only way to run Javascript outside a browser, and other ways of doing so existed long before Node.js arrived. Most limitations people put on technology are artificial constructions rather than real constraints. tedd: I wouldn't trust any stats you might find since, as has been pointed out, it's incredibly difficult to accurately measure. I'd be careful with the word popular because it really depends on what you're measuring. If you're talking public websites then I'd agree that, anecdotally at least, PHP is more common than any other server-side language. If you're talking about public site visitors or page views it's definitely the most popular, but that's massively skewed by Facebook if you accept that their way of using PHP can still be called PHP. Enterprise usage of PHP is far lower, mainly due to Microsoft's dominance, but I get the feeling this is changing, albeit incredibly slowly. If he means Java is the most popular as in developers would prefer to use it then I'd definitely disagree, but I wouldn't necessarily say that PHP is at the top of that list either. Ultimately I'd want to know what he's trying to prove by saying that. If he's purely engaging in a mine's bigger than yours discussion I'd walk away, leave him to his petty games and actually accomplish something with the time instead. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Nmap works by throwing out requests on a bunch of different ports, not just ping, which is slow, so I'd be surprised if Zmap could really rival that while giving the same results. Bearing in mind there are over 4,000 million (I won't say billion, because that's a million million, despite what the Americans say!)

Find everything that's doing that and look at each instance in detail. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] how to see all sessions sets in server
On 4 Aug 2013, at 14:36, Farzan Dalaee farzan.dal...@gmail.com wrote: I need to inspect each visitor to show how online or who offline for chat Like facebook chat PHP sessions is a really bad mechanism to use to accomplish this. In the past I've used memcached or redis for presence indicators. Both allow you to set keys that expire after a set period. The problem with this is that a user can appear to be online for up to set period seconds longer than they actually are. In the system I'm currently building I've got a node.js daemon to which the browser connects. That daemon exposes an API that the rest of the system can call to get lists of online users, which is easily gathered since it's just the list of connected users. There is then no delay between the browser closing the connection and the daemon deciding that user is no longer online. If you have a chat system I'm curious as to how it works, since presence is usually tied closely to how the client is detecting new messages. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Either the code you posted isn't the actual code, or if it is, the errors
should be rather obvious. Post *actual* code.
The error is rather obvious: it loops around an array running an update
statement that will modify a single row in the table, so it's not surprising
that it appears like only the last entry in the array has been stored.

OK. Sorry. I thought it was a PHP question for a way to update several mysql
rows by PHP code.
If you want to UPDATE several rows then you must have unique identifiers for
those rows. If you don't then I'm guessing what you actually want to do is
INSERT those rows.
It's off-topic in the same way as asking a mechanic how to fit a bunch of stuff
in your car. It's the MySQL part that you're having a problem with, not the
PHP. I strongly recommend that you use the MySQL command line to run the
queries you think you need to run, checking what the table looks like after
each one. Once you know what queries you need to run you will more effectively
be able to write the PHP wrapper around those queries.

I will use my application on iPad and find it more easy to use multiple
select lists than one big list with all 200 values at once.
In that case I would recommend using a text input field and validate it with
javascript and then validate it again on the server-side with PHP. With
multiple select fields the only way you'll know which one the user (i.e. you)
meant is by resetting the others to an empty value whenever one of them changes.

Whatever the reason for this, I'd recommend you always specify a path relative
to the current script.
In PHP 5.3+:
$fcontents = file(__DIR__.'/docs/admin-email.txt');
Prior to 5.3:
$fcontents = file(dirname(__FILE__).'/docs/admin-email.txt');

I know it works as designed and I know it is documented like this but that does not mean that it is a good feature, does it? So lets talk about the question: Is that behaviour awaited by PHP software developers? Is that really the way PHP should work here? May we should change that?! BTW: I talked to some collegues and friends since my first post. They all guessed that 'PHP' == 0 is false within a few seconds. I think the weak-typed-PHP is a little to weak at this point. I don't know what the actual reasoning is; if you want that I suggest you ask on the internals list, but be careful how you phrase the question. If it's pure curiosity then that's fine, but whether you agree with the reasoning or not it's gone way past the point where it can be changed. My take it that the behaviour is perfectly reasonable. When you compare two different types it has to convert one of them. If you're comparing a string to a number it seems logical to me that the number should be the preferred type, so the string gets converted. What would you expect array(5) == 5 to give you? Would you expect the 5 to be converted in to an array? No. The reason it looks odd for PHP == 0 is that there's no reason why the 0 should not be converted to 0, except that strings and numbers are not the only types available and there has to be an order of precedence. And consistency is key. As for how strings get converted to numbers I have no idea why it will take everything up to the first non-e|E|. character. The documentation[1] simply states the behaviour and doesn't go in to why. However, I have to ask why it matters? Why would you want to convert '8315e839da08e2a7afe6dd12ec58245d' to an integer? If you have code that's juggling it automatically, be more explicit. It's fine to be interested in the reasons why it does what it does, but if it's causing you problems then the issue is with your code not being explicit enough, not PHP. -Stuart [1] http://php.net/language.types.string#language.types.string.conversion -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ideally, I want a scope aware include function, so I can say _something_
like ...
$s_XML = require_once __CLASS__ . DIRECTORY_SEPARATOR .
'normalisedError.xml';
and have the include be aware of the local scope (so $o_XML and $this are
all happy).
I know I can write a template parser, but I'm just missing an obvious
solution that isn't fat and doesn't require a massive learning for the
other devs.
Ideas?
normalisedError.xml:
?php
return END_XML
the xml here
END_XML;
Then in your class your require_once line will work. However, use require
instead of require_once otherwise if the function gets called twice it won't
work the second time.

This is where the interface is defined as an API for others to implement and/or use which then enables users to pick and choose the combination of implementations they want to use based on their requirements without needing to change any of the code of either class. Abstract classes are more likely to be used where there is a set of shared functionality that is required by several other classes, but which is not functionally useful by itself. An example of this from a current project of mine is in aggregating news sources (RSS, scraping, custom formats, etc). I have an abstract base class which supplies common code to parse and process data, and some abstract methods that must be implemented by any class that extends it because the abstract class methods may call them. The abstract class also contains a static factory method for getting instances of the type-specific classes. With this architecture the users of the abstract class never see the derived classes so there's no need to publish an interface for them to use.

This is where the interface is defined as an API for others to implement and/or use which then enables users to pick and choose the combination of implementations they want to use based on their requirements without needing to change any of the code of either class. I understand the stated differences between abstract and interface. I can cite what the differences are, but I don't see the practical application differences. To me there is no difference between an abstract class (without method declarations) and an interface. That's true, there is no difference if the abstract class has no method declarations. But by the same token, that's the difference. It's a syntactical difference rather than a conceptual difference. However, I view an interface as a statement (a contract) where IF you want someone to use your code you outline the methods you require them to flesh-out in their code -- but I would like to see a simple example of that. That's not what an interface is for. I can see how the word is confusing as you can call the API of both an interface and a class (abstract and not) an interface, but in this context the word interface means the thing itself, not an aspect of the thing. An interface is an interface and does nothing more than define the API. An abstract class may also have methods and member variables. I vaguely get the logging example given by Larry, but I'm not good at abstract thinking -- I need a concrete simple example. I tried to create a demo where I had a Toaster Class that contained breadNumber() and toastSetting() methods and then created an interface so my students could use the Toaster, but it didn't really hold up as well as I wanted. So, can anyone give me a simple example where an interface is used so I can easily explain why they are important? I've knocked up a quick example of the logger use case: https://gist.github.com/3ft9/5599326 Note that if I publish that iLogger interface to others and let them provide implementations against it people can use their logging classes with my user class without any changes. Yes, this could be accomplished by using abstract class instead of interface but then it's more than just an interface that I'm publishing. If you're looking for a reason why interfaces exist when abstract classes can accomplish the same task you need to talk to someone more academically minded than me. For me, interfaces have their place because they specifically limit what you're getting from a third party to an API definition, rather than it also containing additional code that should be audited before being used in your software. Your toaster example would work, but I think you need to switch from the large object to a smaller aspect for it to make sense. Rather than being able to replace the whole toaster from their code, imagine if they wanted to replace a module within the toaster that determines the pattern to be burnt on to the bread. The Toaster class could optionally take an object that implements iToasterPattern which the students could supply to change the pattern burnt. To enable them to use that you would provide them with the API to the Toaster object so they can talk to it, and the iToasterPattern interface so they can provide their own implementation of iToasterPattern. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I don't understand why mysql_connect should append something in the case of a

Nothing is being added by anything. When you log in to MySQL it takes both the
username and the IP address/hostname of the machine you're logging in from and
looks those up in the users table. This means that user abc logging in on
localhost becomes abc@localhost. User abc logging in from 192.168.0.187 becomes
abc@192.168.0.187, and is treated as a completely separate user from
abc@localhost.
The host comes from your end of the connection. So if you connect on localhost,
your end is also localhost. If you connect on the IP address or hostname, your
end is the rDNS lookup of your IP address - note that this may be the same
address as the one to which you are connecting, but will represent a different
user to @localhost as far as MySQL is concerned.
The only thing that may be being added to the variable when the form data is
parsed is slashes, and then only if you have magic_quotes_gpc switched on in
php.ini. I believe this has already been eliminated as the cause earlier in
this thread.
The problem you describe is not possible, so I'm betting your description is
missing something. Given a request with POST parameters of username=abc and
password=def, the following two lines are equivalent:
mysql_connect('localhost', 'abc', 'def');
mysql_connect('localhost', $_POST['username'], $_POST['password']);
If this is exactly what you're doing then something very strange is going on.
If this is not exactly what you're doing, please narrow your code down to the
minimum required to demonstrate the problem and post it somewhere like gist.com
then send us the link.
However, a more important question for me is why you are doing this. You say
you are aware of the security implications, and that you'll deal with that

If that is the case then why does logging in with exactly the same params

What makes you so sure it's not?
It is. I promise you it is. You're not seeing it because you're not getting an
error logging in. Do it on the command line again, but use a username that
doesn't exist and you will see the host it's adding in the error message.
I am doing exactly as you stated:
mysql_connect('localhost', $_POST['username'], $_POST['password']);
Except that I am first storing $_POST['username'] in local $user and
$_POST['password'] in local $pass first and then passing those to
mysql_connect. And I am connecting to a remote server, not localhost.
Side note: why are you putting them in other variables first when you're only
going to use them in that one place? It's a waste of memory. It's a minor
niggle but it's a pet hate of mine.
I have already documented both the exact HTML and PHP code in this thread and
so see no need to post it elsewhere.
And you're saying that when, instead of using $_POST variables you hard-code
the username and password in the script it work? I doubt it.
On the command line are you simply doing mysql -u username -p and then
entering the password? In that case it's using localhost. Is MySQL running on
the same server as PHP? If so, try changing the remove server name to
localhost in your script. I'm better a magnum of decent champagne that it
works.
It's very rare (and pretty stupid) for a web host to allow remote servers to
connect to their MySQL instances, unless they have a shared MySQL instance for
all of their customers. Given that you have command line access to the MySQL
server, and can log in without specifying the host, I'm thinking you're trying
to use it in a way they don't allow.

If this is exactly what you're doing then something very strange is going
on. If this is not exactly what you're doing, please narrow your code down
to the minimum required to demonstrate the problem and post it somewhere
like gist.com then send us the link.
However, a more important question for me is why you are doing this. You say
you are aware of the security implications, and that you'll deal with that
later, but I question how you're going to deal with it. What exactly are
you developing that requires DB credentials to come from a form on a web

I found some code at php.net that does this:

And that is working for me and giving me what I need.
But do you ACTUALLY know what time zone is stored IN the database? What
if
te database was from another server?
One of the 'standards' adopted when working world wide is to ensure what
is
stored IN the database is always UTC based. So you can always compare
times
on the same consistent base. The only time you need the offset is to
display
a local time, and that is either the time local to the server, or the
time
local to the client.
The 'default' timezone is not necessarily the right one in either case ;)
I misspoke - the data in the db is in UTC. This is used to covert the
time of day on the server to the user's local timezone.
You are aware that the code you used is really bad practice, right? You're
basically hiding the error no default timezone set by getting the default
timezone, which returns an error; surpressing that error, providing the
date_default_timezone_set function with the default value of
date_default_timezone_get if none is defined (which there should!!), being
UTC.
So in short, you're saying set the default timezone to the default timezone
if no timezone is set, which I know there is not. That's very hard to
understand for future programmers reading your code. Why not just set
date_default_timezone_set('UTC'). It's clear, resolves the warning and
works perfectly, instead of relying on vague defaults somewhere, in the hope
they're set right.
On a sidenote; the reason why your original fix did not work:
$deftz = date.timezone;
Is because date.timezone is an ini setting. Not valid PHP code. And the
error actually tells you you need to SET date.timezone, not set a variable
TO the ini setting. In other words, you wanted date.timezone = UTC instead
of $tz = date.timezone (which makes no sense anyway)
But UCT is not the timezone. When this app runs in New Mexico (where I
am) it's Mountain time. When it runs in NY it's Eastern. When it runs
in Tokyo it's JST, etc. The user has the option of setting the
timezone all times are displayed in. They can select any timezone
regardless of where they are. The app displays the last update time in
the user selected TZ. So I have to convert the time I get from the
server to th...@lsces.co.uk@gmail.com@gmail.com
You don't need to convert anything! Store as unix timestamps, and call
date_default_timezone_set with the user's selection before you use any other
date-related functions and everything will just work. This is not as hard as
everyone seems to think!-Stuart

I agree with Stuart.
To minimize the overhead of testing every possible undefined variable with
isset(), I assign them at the top of the page which uses them. e.g.,
$userInstrHtmlSizeWarning = false;
$currentUserRecArray = array();
if(!isset($_SESSION['pwPassed']))$_SESSION['pwPassed'] = false;
I also have this snippet at the top of my app config file.
if(true){ // TRUE for debug only
ini_set(display_errors, on); //use off if users will see them
error_reporting(E_ALL)
$error_reporting = 'span style=color:redError display and logging
on/span ';
}
else $error_reporting=null;
I put this at a convenient place on the page so I don't forget to turn off
the error reporting when the code goes live.
if($error_reporting) echo $error_reporting;

Re: [PHP] Apache to serve RESTful requests using PHP
On 10 Feb 2013, at 06:57, AmirBehzad Eslami behzad.esl...@gmail.com wrote: Stuart, thanks for your detailed response. I find it unlikely that Apache is your bottleneck, especially with a service involving MySQL. How have you come to this conclusion? Apache is the entry-point to our service, and I did a benchmark with AB to see how it can handle concurrent requests in a timely fashion. After a number of 50 concurrent requests, the average time per request reached from less than a second to 5 seconds. I *strongly* recommend you try the same test with nginx. Unless this is due to the way your code works I'm confident you'll see this effect disappear! As far as keep-alive goes, how frequently will individual clients be accessing the service? There are only a few clients that call the service. These clients are PHP-driven web pages. Each page has its own unique ClickID and a set of other unique parameters per user visit. These pages send these parameters to the service using php-curl, and expect a generated response to be returned. That's why I'm saying each request and response is unique. Whenever a user visits a web-page, there would be a call to the web-service. At the moment, we don't know number of concurrent visits. We're looking for a way to figure that out in Apache. Is there a way to see if the requests are using the previously keep-alived http channel? Because same client will send requests to the service, and I'm curious to know if the Apache will allocate the already-opened channel, or will create a new one? If it's making one request to your service per page request, keep-alive is pointless as it won't be able to reuse the connection. In this instance I would turn keep-alive off. If you are using joins to pull in extra data (i.e. IDs to a name or similar) look at using Memcache for those, but make sure that when they're updated in the DB they're also updated in Memcache. Memcache or Redis, I'm going to add a caching layer between MySQL and PHP, to store the de-normilized data. For simple caching I'd recommend Memcache over Redis, purely because Redis is more complex due to its support for sets, queues and other very useful stuff. The only reason I'd use Redis for simple caching is because it can periodically flush the cache to disk so if it has to restart it can start with a primed cache. However, in most cases that is not a huge advantage. If each request and response is unique you need to be careful about what you choose to cache such that you don't incur caching costs without reaping benefits that make it worthwhile. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Since this service will be used by many clients in a concurrent manner, we'll face with a high-load on our web-server. But web-services are different from web pages, for instance they don't include images, or in this case we only serve JSON. I'm wondering what are the recommended configurations for the Apache web-server in these situations? Should we disable keep-avlie? What about other directives? Apache is our bottleneck, and we're trying to optimize it. Should we use nginx instead? I find it unlikely that Apache is your bottleneck, especially with a service involving MySQL. How have you come to this conclusion? I would personally recommend nginx + php-fpm over Apache + mod-php every time. The pre-request memory footprint is massively reduced and I've seen nothing but upsides since migrating most of my client's sites, and my own. As far as keep-alive goes, how frequently will individual clients be accessing the service? Are they likely to be using client software that supports keep-alive? You basically want to weigh up the cost of potentially keeping the connection open against the likelihood that the majority of clients will make use of it for multiple requests. My gut reaction based on your description would be to set it to 1 as suggested by Bastien so it has minimal impact while still allowing clients who support it to be that bit more efficient. Focus your optimisation efforts on MySQL. If the bulk of requests will be reads you'll benefit from read-only slaves. If the data can be neatly sharded then that's definitely worth investigating. When writing data get it as close to the structure that will be needed when reading, including de-normalising it if necessary. If you are using joins to pull in extra data (i.e. IDs to a name or similar) look at using Memcache for those, but make sure that when they're updated in the DB they're also updated in Memcache. Do the DB query, get all the Memcache keys you need a do a multi-get request. The other way to do this is to de-normalise as discussed above, but that makes updating the data very expensive (as every row needs to be updated). In my tests breaking it out to a Memcache instance was far more efficient. At the end of the day there will always be things you can do that are only applicable to your service, but the general rule is to need to do as little as possible to serve the data when it's requested, shifting as much of the work as possible to when it is written (assuming a mostly-read service). -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You mention the headers_sent() result immediately after the header() function

Plus the latter seems to be a more robust way of making the changes. Thanks, and apologies if this has been asked before and I missed it. I'm just not sure how to phrase this for a search engine. Nelson You could use an existing templating solution, like Smarty, although for what you want to do it might be overkill. A few str_replace() calls shouldn't produce too much overhead, but it depends on the size of the text string in question. If it's just a couple of paragraphs of text, no problem, something closer to a whole chapter of a book will obviously be more expensive. You could try eval() on the block of text, but if you do, be really careful about what text you're using. I wouldn't recommend this if you're using any text supplied by a user. As a last option, you could have the text stored as separate parts which you join together in one string later. This might be less expensive in terms of processing power required, but it also makes maintenance more of a hassle later. Thanks, Ash http://www.ashleysheridan.co.uk

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.
And of course, nothing is allowed to have changed since 1978! Using a switch in
that manner is normal for me. Should I change my style simply because you don't
agree with it? If so, why don't you change your style because I don't agree
with that? Code is art; there is no right way to do it. Can code be shown to
be more efficient, elegant, faster, cleaner? Yes. Right or wrong? No.
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.
Why is it their fault for doing 100mph and not yours for assuming they're only
doing 70mph? I'm not saying they're right to be doing 100mph, but I'm
definitely saying you're wrong for assuming they're only doing 70mph.
Assumptions are the mother of all f*** ups.

IN your example, you are using a switch syntax that is nothing like that. I
think that your case statements are not actually evaluating the value of
$count, but are themselves evaluating to a true value that has nothing 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.
I don't see how it breaks the principle of least surprise (which is a new one
on me. KISS, yes. Least surprise? Wassat?). If you consider that behaviour to
be surprising the don't ever go near Perl.
A switch statement is basically saying take this value and compare it to each
case below in the order they're presented until one matches, then execute that
block of code until you hit a break which will jump execution out of the switch
statement. I don't see how making this value true or false makes it any more
surprising than if it's squirlookle.
The job of a programmer is not to be clever with a view to impress those
who follow, but to achieve the desired outcome while at the same time making
life easy for those who follow.
I don't consider that usage of the switch statement to be clever. It's a
valid usage of the statement which gives it a lot more power. Specifically the
ability to have the code for a given case deliberately fall through to the next
case block is worth any price of admission. And finally, in my opinion, it's
far cleaner than a succession of if/elseif/else statements, and ultimately gets
compiled to very similar opcodes.
I agree that the job of a programmer is to balance providing a fast, efficient,
correct solution and minimising maintenance issues. I see neither side being
compromised by using a switch statement in this manner, in fact I see both
sides potentially getting a boost. Just because the usage is unfamiliar or even
surprising to you doesn't mean it's wrong.
