PHP script execution mode

LAKid

Can anyone tell me which execution mode is better for low memory vps?

Apache mod_php (run as Apache's user)
CGI wrapper (run as virtual server owner)
FCGId (run as virtual server owner)

tux

php-fpm

LAKid

I noticed that /usr/bin/php-cgi eats a lot of ram, that's why...

It's probably because PHP encourages people to write crappy code.

Can php-Fpm be used in virtual environment such as webmin/virtualmin?

Nonsense!

<?php

$h = "h";
$e = "e";
$lone = "l";
$ltwo = "l";
$o = "o";

$string = $h . $e . $lone . $ltwo . $o;

print $string;

?>

@Damian here is some related fun

php-fpm plus ondemand scheduler n_n

Thats too easy!

<?php
// Making it easy for different langs!
function h(){return "h";}
function e(){return "e";}
function l(){return "l";}
function o(){return "o";}
function w(){return "w";}
function r(){return "r";}
function d(){return "d";}
function z(){return "!";}

// sprintf is so cool!
$stringone = "%s%s%s%s%s";
$stringtwo = "%s%s%s%s%s";
$stringthree = "%s";
$stringfour = "%s %s%s";

// If we need to change it...
$command = "print";

// Easy variable changing!
$h = "h";
$e = "e";
$l = "l";
$o = "o";
$w = "w";
$r = "r";
$d = "d";
${null} = "z";

// Let's build the string
$string = sprintf($stringfour,ucfirst(sprintf($stringone,$h(),$e(),$l(),$l(),$o())),ucfirst(sprintf($stringtwo,$w(),$o(),$r(),$l(),$d())),sprintf($stringthree, ${null}()));

// Lets do whatever with it!
eval("$command($string)");
?>

php-fpm for frontend
beanstalkd for backend tasks (resizing an image, etc)

did anybody actually use php-Fpm in virtual environment ?

Yes. It's using 15mb ram on my Xen VPS.

LAKid

Apache mod_php uses 7 mb in openvz...

Adam

@LAKid mod_php doesn't scale as well.

That's like saying food encourages people to get fat.

I don't disagree that there are many bad PHP scripts, but there are many good ones as well.

Guys check out Mod_ruid2. its the perfect balance of security and speed. Either that or check out MPM-ITK

foreach ($userList as $user) {
$query = 'INSERT INTO users (first_name,last_name) VALUES("' . $user['first_name'] . '", "' . $user['last_name'] . '")';
mysql_query($query);
}

Good one, but sometimes you can't do that trickery without doing a loop

OneTwo

@Derek is it my idea or that's not security safe?

That PHP code just does (Amount of Users) x MySQL Query.

So if you have 25000 users, your running 25000 MySQL queries.

The Google recommendation basically recommends you put it into one query, but then the fact that you have to add it all into an array, then implode it. So if you have 25,000 users thats going to be slow anyway.

It also won't work with MySQL_insert_id.

exussum

Surely (firstname,lastname) values as a string.

Then for(;;)
$sql .= '(', $firstname ,',',lastname ,')';

would be better ? Also check for sql injection

I think the lowest memory usage is Apache mod_php (run as Apache's user).. I'm using it on my personal server.
But prefer using FCGId (run as virtual server owner) on share environment (share with other user).
Any other suggestion?
Thanks..

mod_php means every apache process has it's own php processor in it. That means every connection to apache needs at least 10-15mb ram. I often have 50-100 keepalive connections to my webserver. I would need almost 500mb-1GB ram for keepalives if I used mod_php.

PHP with uWSGI seems to be an interesting alternative, advertised to have better performance.
