Re: Beginning /< and end of word /> in eregi_replace

You have your answer, just use this: $outstring = eregi_replace("badword","goodword",$stringtocheck); It'll replace it whether it's at the beginning or end of a string, embedded in a word, or by itself. Isn't that what you want? Actually, it'd be better and faster to just use str_replace() instead of a regular expression... ---John Holmes... ----- Original Message ----- From: "John S.
