What do I do with this?

Okay, I was reading a PHP book and I am up to Matching Strings to Patterns, and I have things, like C$ which is supposed to check if the last letter in a string is a C. So how do I use this? I tried putting it in the if () thing but that didn't work. So where do I put it?

What? You'll need to post some code or something, your post makes no sense. C$ is nothing in php.

The c$ is supposed to be plugged into something to determine if a string ends in c. I don't know what to plug it into.

Ah... I think your talking about regular expressions. Take a look at [url=http://php.net/preg_match]preg_match[/url]() and related functions.

Surely your book also describes [i]how[/i] to use patterns.

No it hadn't said anything about that. I guess they forgot that part? Thanks :)

Check the last char of a string for a specific letter:
[code]
<?php
$c = "This is a Test";
if (substr(strtolower($c), -1)==(strtolower("t")){
  echo "C ended in t";
}
?>
[/code]
