Determine how long PHP executed so far

Question

I need to determine how long a PHP function has been running so far.

What are some options to find out how long some PHP code takes to run?

I'm using zend framework.

Answer 1

Call microtime(true) function to fetch current time with milisecond resolution.

<?php
$startTime = microtime(true);

/*stuff is going on*/

echo "Elapsed time is: ". (microtime(true) - $startTime) ." seconds";

Answer 2

microtime — Return current Unix timestamp with microseconds

<?php
$time = microtime(TRUE);

//...code here...

print (microtime(TRUE)-$time). ' seconds';

Answer 3

You could simply use PHP's standard timeout, and implement a shutdown function.

function say_goodbye() {

    if (connection_status() == CONNECTION_TIMEOUT) {
        ... do your special processing to save the process state here
        ... then formulate a response for the browser
    }
}   //  function say_goodbye()


register_shutdown_function("say_goodbye");

Note that you can set the shutdown function to accept parameters

EDIT

function say_goodbye($controller1,$controller2) {

    if (connection_status() == CONNECTION_TIMEOUT) {
        ... do your special processing to save the process state here
        ... then formulate a response for the browser
    }
}   //  function say_goodbye()


$ctl1 = new DBController();
$ctl2 = new OPController();

register_shutdown_function("say_goodbye",$ctl1,$ctl2);
