Re: unexplainable - page generation time class

[Ian Firla <ifirla@xxxxxxxxxxx>]

I think the problem is how, when and where you're calling things.

Basically, your code is fine. I modified it slightly and get the correct
output. This could still be cleaned up and optimised significantly;
however, I think you can take it from here:

Your Class:

<?php
class page_gen {
        //
        // PRIVATE - DO NOT MODIFY
        //
        var $cls_start_time;
        var $cls_stop_time;
        var $cls_gen_time;
        
        //
        // FIGURE OUT THE TIME AT THE BEGINNING OF THE PAGE
        //

        function start() {
            $microstart = explode(' ',microtime());
            $this->cls_start_time = $microstart[0] + $microstart[1];
            return $this->cls_start_time;
        }
        
        //
        // FIGURE OUT THE TIME AT THE END OF THE PAGE
        //
        function stop() {
            $microstop = explode(' ',microtime());
            $this->cls_stop_time = $microstop[0] + $microstop[1];
            return $this->cls_stop_time;
        }
        
        //
        // CALCULATE THE DIFFERENCE BETWEEN THE BEGINNNG AND THE END AND
COLOR CODE THE RESULT
        //
        function gen($start, $stop) {
            $this->cls_gen_time = $stop - $start;
            return $this->cls_gen_time;
        }
    }
?>

index php that calls it:

<?PHP

require_once("timer.php");

$page_gen = new page_gen;

$start=$page_gen->start();
sleep(2);
$stop=$page_gen->stop();

echo("start/stop: $start $stop<br><br>");

$gentime=$page_gen->gen($start, $stop);

echo "generation time: ". $gentime;

?>

Output:

start/stop: 1110096261.12 1110096263.13

generation time: 2.00168681145

All the best,

Ian
