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