It’s been a bit silent here over the last weeks. That’s due to a little side project i just launched at custom-wp.com.

The new site is a showcase for WordPress sites which is more or less a frontend to my daily browsing routine. Kind of webzappr for WordPress related things only.

Go – check it out and let me know what you think about it.

I would be happy for any kind of feedback.

Here is a little workaround that was simple but good enough to provide the necessary information. It might not work on windows systems though.Also you should be aware that it will never give you the same results as memory_get_usage(), but it is working well to spot where your memory consumption grows and helps to find leaks.

<?php

if ( ! function_exists( 'memory_get_usage' ) ) { 

    function memory_get_usage( $ps_opt="u" ) {
        global $pid;

        $ps=shell_exec("ps ".$ps_opt."p ".$pid);
        $ps=explode("\n", $ps);
        if(count($ps)<2){
            return false;
        }

        $ps=explode(" ", ereg_replace(" +", " ", trim($ps[1])));

        return (int) $ps[4];
    }

}

$pid = getmypid();

if ( $pid )
    printf( "mem: %d\n", memory_get_usage() );

for ( $i=0; $i<=10000; $i++ ) {
    if ( $i % 1000 == 0 )
        printf( "mem: %d\n", memory_get_usage() );
    $memeater[] = $i*$i;
}
?>

The important part is in line 3-21.
In line 3-19 a workaround function for memory_get_usage() that uses the “ps” command is defined.
The process id of the currently running PHP process is determined in line 21 and stored within a global variable.
Lines 23++ are just to show an example usage for this code.

Once again – this function is not made to determine any exact memory consumption values or replace memory_get_usage(). It is just a workaround, I use here and there to spot memory leaks in PHP scripts.
