PHP Control Structure :Declare()

Question

I'm having a hard time understanding the PHP control structure declare() and where/how it would be used.

http://us.php.net/manual/en/control-structures.declare.php

I was hoping someone could explain this to me.

Thank you in advance.

Take a look at http://www.tuxradar.com/practicalphp/4/21/0

SUMMARY:

Put simply, a tick is a special event that occurs internally in PHP each time it has executed a certain number of statements. These statements are internal to PHP and loosely correspond to the statements in your script. You can control how many statements it takes to set off a tick using the declare() function, and you can register functions to execute when a tick occurs by using the register_tick_function() function.
