number function calls

[mjdaly]

Heya, is there any way a function can tell how many times it has been called during the execution of a php script?

Declare couner varible as static:

<?php//idea from php.net

function Test()
{
   static $a = 0;

   //do your stuff here

   $a++;
   return $a;
}
?> 

Function will return the number of times it has been executed.

That works great, thank you.

Here's a way to do it so that you have to add only one line to each function you want to track, plus you won't have to alter the function's return value:

function function_count($func = '')
{
    static $ct = array();
    if ($func) {
        @$ct[$func]++;
    } else {
        foreach ($ct as $key => $val) {
            echo $key . '(): ' . $val . '<br />';
        }
    }
}

function some_function()
{
    function_count(__FUNCTION__);
    // Your code
}

function other_function()
{
    function_count(__FUNCTION__);
    // Your code
}

for ($i = 0; $i < 16; $i++) {
    some_function();
}
for ($i = 0; $i < 8; $i++) {
    other_function();
}

function_count();
