This doesn't sound like it requires the overhead of a regex function.  
Check out  instead.

hehe... that's what regular expressions are for.
they're extrememly powerful... but that doesnt mean that
you should only use them for extremely complicated situations.
they work great everywhere... 

if you dont like "overdoing it", you might as well loop
thru the string character by character, C-style.  :-)

Couldn't he just do something like

if (strstr($text, "aol.com")) {
   MyFunction();
} else {
   echo "Not Found";
}

It just seems like using ereg for this is like killing a fly with a
sledgehammer

read the docs for ereg... i hardly use it, so i dont know
for certain if it will match. (althouth the use of "^" at
beginning *and* end suggests that it wont do what you expect)

preg will match "aol.com" with this regexp:

preg_match('/aol.com/', $string )

Will this work?

$string = "http://www.aol.com/";;

if (ereg ("^aol.com^", $string) {
}
else {
}

have a look at ereg() (regular expression match)  functions in manual.
they'll do exactly what you want.

Try researching regular expressions. In PHP, look at the preg and ereg 
groups of functions.
