RE: [PHP] how the "ticks" works?

[Martin Towell]

As the manual says - it executes the "tick" function every 'n' low-level
statement - but what's counted as a low-level statement, I don't know...

It appears that, in the example, the low-level statements are the "for" and
the "echo"

If anyone can shed light on this subject, I'd be interested too

Subject: [PHP] how the "ticks" works?


I don't understand how the 'ticks' works:       please help me.

<pre>
<?php
// A function that records the time when it is called
function profile ($dump = FALSE)
{
    static $profile;

    // Return the times stored in profile, then erase it
    if ($dump) {
        $temp = $profile;
        unset ($profile);
        return ($temp);
    }

    $profile[] = microtime ();
}

// Set up a tick handler
register_tick_function("profile");

// Initialize the function before the declare block
profile ();

// Run a block of code, throw a tick every 2nd statement
declare (ticks=2) {
    for ($x = 1; $x < 50; ++$x) {
        echo similar_text (md5($x), md5($x*$x)), "&lt;br&gt;";
    }
}

// Display the data stored in the profiler
print_r (profile (TRUE));
?>
</pre>
