Variables in Regular Expresions?

[Anon]

When I use $string in a regular expression replace, it interprits that as 'the word string at the beginning of a string'. Is there any way I can still use a variable as the match string without that error? Thanks.

PS: Here is my code:

$Return_of_the_thingy = eregi_replace($string, "", $Thingy);

Put the variable inside double quotes.

eregi_replace("$string", "", $Thingy);

PHP replaces a variable with its value when it is inside double quotes.
