[SOLVED] memory_get_peak_usage alternative?

[phil88]

I need to use memory_get_peak_usage(), but it's only available in PHP versions > 5.2.0 and I have 5.0.4.

 

I can't use memory_get_usage() either because PHP wasn't compiled with --enable-memory-limit.

 

So, because of this...I'm stuck. Does anybody know of an alternative implementation of either function that would work on my set up? There's no way for me to upgrade PHP or recompile it, I'm stuck with this environment unfortunately.

 

 

Bit of useful info;

PHP 5.0.4, not compiled with --enable-memory-limit

Windows XP

 

I'm guessing that I'm going to need to use exec(), but the examples in the comments on php.net don't seem to be working.

yes you will. the following works (from php.net)

<?php 
if( !function_exists('memory_get_usage') ) 
{ 
    function memory_get_usage() { 
        if ( substr(PHP_OS,0,3) == 'WIN') 
        { 
               if ( substr( PHP_OS, 0, 3 ) == 'WIN' ) 
                { 
                    $output = array(); 
                    exec( 'tasklist /FI "PID eq ' . getmypid() . '" /FO LIST', $output );
                    return preg_replace( '/[\D]/', '', $output[5] ) * 1024; 
                } 
        }
        else  { 
            $pid = getmypid(); 
            exec("ps -eo%mem,rss,pid | grep $pid", $output); 
            $output = explode("  ", $output[0]); 
            //rss is given in 1024 byte units 
            return $output[1] * 1024; 
        } 
    } 
} 
?>

Either I have magical scripts, or it doesn't work on my set up. It always returns 0.

 

Edit:

I tried running the exec(...) stuff from a batch file, and it said:

'tasklist' is not recognised as an internal or external command, operable program or batch file.

 

Is this because I have XP Home as opposed to Pro or a server edition?

Ok, I managed to copy tasklist.exe off of another PC (that had XP Pro) and put it in my system32 folder and now it works

 

Thanks for your help!
