Use Strace to view the C language PHP source code

If you want to see C-level PHP code you need to use Strace

This default is installed, if no installation can

#yum Install Strace

View the httpd process (no Web server is required to install one)

#ps Auxw | grep httpd

There are multiple that must stop Apache

[[email protected] usr]#/usr/local/webserver/apache2/bin/apachectl stop

Start single Process httpd

[[email protected] usr]#/usr/local/webserver/apache2/bin/apachectl-x-K Start

Re-use #ps Auxw | grep httpd View Only single frequently, note the process ID

Bind the Strace to Apache

#strace-P 28224

Algorithm

Quickly sort PHP code

<?php

function QuickSort ($arr)

{

$len = count ($arr);

if ($len <= 1) {

return $arr;

}

$key = $arr [0];

$left _arr = Array ();

$right _arr = Array ();

for ($i =1; $i < $len; $i + +) {

if ($arr [$i] <= $key) {

$left _arr[] = $arr [$i];

} else {

$right _arr[] = $arr [$i];

}

}

$left _arr = QuickSort ($left _arr);

$right _arr = QuickSort ($right _arr);

Return Array_merge ($left _arr, Array ($key), $right _arr);

}

$arr = Array (6,3,8,5,9,2,10);

Echo ' <pre> ';

Print_r (QuickSort ($arr));

?>
