PHP script for memory usage

**Ucchal** · 14-06-2010

Hello,
I have hosted my site and using the cpanel to control the activities and other things. Now I need to modify some of the php code to get the memory usage for the site. How can I do this? I have tried some scripts but non of them was really useful. So, if you have some of the scripts that I may use to get the memory usage, it would be great. Thank you.

This is the basic script that does this job

Code:

<?php
// This is only an example, the numbers below will
// differ depending on your system

echo mem_usg() . "\n"; // 36640

$a = str_repeat("Hello", 4242);

echo mem_usg() . "\n"; // 57960

unset($a);

echo mem_usg() . "\n"; // 36744

?>

To get the memory usage in KB or MB

Code:

<?php
    function echo_memory_usage() {
        $memory_usg = memory_get_usage(true);
       
        if ($memory_usg < 1024)
            echo $memory_usg." bytes";
        elseif ($memory_usg < 1048576)
            echo round($memory_usg/1024,2)." kilobytes";
        else
            echo round($memory_usg/1048576,2)." megabytes";
           
        echo "<br/>";
    }
?>

Alternatively you can use this script too

Code:

function memory_get_usage_by_tasklist()
{
    $otpt = array();
    exec( 'tasklist ', $otpt );
    foreach ($otpt as $value)
    {
        $execu=explode(" ",$value);
        $cnt_ex=count($execu);
        if (eregi(" ".getmypid()." Console",$value))
        {
            $mem_sz=$execu[$cnt_ex-2]." Kb";
            return $mem_sz;
        }
    }
}
echo memory_get_usage_by_tasklist();
?>

Even i was find a script for doing the same job. I have found one and this works for me very well. See if this works for you

Code:

<?php
function m_usage()
{
     $processid = getmypid();
     exec("ps -o rss -p $processid", $otput);
     return $otput[1] *1024;
}
?>

This is what you have to do

Code:

memstat();
wst_mem(10000);
memstat();
wst_mem(10000);
memstat();

Check out this code

Code:

class nd {
    public $prtnd;
    public $chnd = array();
    function nd() {
        $this->nodeValue = st_rep('0123456789', 128);
    }
}
function createRelationship() {
    $prt = new nd();
    $chd = new nd();
    $prt->chnd[] = $chd;
    $chd->prtnd = $prt;
