In PHP, what is a Tick?

I know that Ticks are not PHP specific and are somewhat related to timing and/or number of operations, but I lack all the understanding that would otherwise allow me to work with them.

Can someone please explain to me what ticks are / do in a simple fashion?

This link (found via Google) says that Ticks are

a underused and powerful feature of PHP that allows you to implement exceptions in PHP4

But you're probably not talking about PHP4, in which case, go with the other answers.

Ticks have been deprecated as of PHP 5.3, and will be removed entirely at some point in the future. ... 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.

In PHP, a tick is like an event which is triggered after every n-th statement (the n is declared using declare), with a few exceptions such as control structures (if, for, ...). It is possible to register a tick handler, which would be called every tick. This is a very rarely used feature, but sometimes it may be helpful, for example, for simple profiling.

I found a decent explanation here. I have used them in writing daemons.

I think declare() might be planned for deprecation. I know it was at one point.

EDIT: It was the ticks directive that was planned for deprecation.
