[SOLVED] any way to show each function cost how much second?

[zgkhoo]

any way/code to show each function use how much time in second?

thanks

[zgkhoo]

for debugging purpose..

thanks in advance

You can invest in an IDE with a "profiler" or use microtime()

 

<?php
$t1 = microtime(true);

myfunction();   // call function

$t2 = microtime(true);

echo $t2 - $t1;    // echo time taken

I use this class

sample code

 

<?

$summarytimer->setPrecision(4);
$summarytimer->startTimer();
... run your function
echo $summarytimer->getElapsedTime();
... run another function
echo $summarytimer->stopTimer();
?>
