Get execution times of a full script or parts of it

PHP-Timing

A simple static class to dissect execution times of a full script or parts of it., _(*1)

Getting Started

Include Timing.php via include, require or composer autoload and use it as a static class., _(*2)

Methods

Timing:: start('name') / stop('name')

Calculate the execution time between two points., _(*3)

Timing::start('random calc');
for ($i = 0; $i < 10000; $i++) {
    $r = rand();
}
Timing::stop('random calc');

Timing:: break

Saves the time elapsed since the script started to the break point, _(*4)

$var = rand();
sleep(2);

Timing::break();

$var = rand();

Timing:: measure('name', callback)

Calculate the execution time of a function, _(*5)

$returnVal = 0;
for ($i = 1; $i < 3; $i++) {
    $returnVal += Timing::measure('someFunction('.$i.')', function() use ($i) {
        sleep($i);
        return $i;
    });
}
var_dump($returnVal);

Timing:: addCallback( callback )

Adds a function called every time a new timing has been saved, _(*6)

Timing::addCallback(function($key, $time) {
    var_dump("Collected timing for: $key: ". round($time,4));
});

Timing:: getTimings($round = 3, $slowThreshold = -INF, callable $cb )

Returns all saved times under a key=>value array, _(*7)

Array
(
    [start] => 0
    [random calc] => 0.0003
    [someFunction(1)] => 1.0001
    [break @ sample.php:45] => 1.0006
    [someFunction(2)] => 2.0001
)
