Re: Help w/ regular expressions for banned words

Thanks for your help. Unfortunately, [:space:]$bannedwords[$i][:space:] would not work, since I need to also check for the first and last word. In a last-case scenario I could write special code for the first and last word, but that may get ugly with bug-checking... but I've already tried "\s+$bannedwords[$i]\s+" to no avail. I believe [:space:] is just a substitute for \s+, right? Yeah, I've tried \<$bannedwords[$i]\> too, unfortunately. Like I said before, eregi_replace("a","[censored]",$string) makes a match, but eregi_replace("\<a\>","[censored]",$string) or eregi_replace("\ba\b","[censored]",$string) does not. Most odd. Thanks for your help, though. Anyone else have suggestions? --Neal on 1/20/01 12:20 PM, CC Zona at cczona@nospam.invalid wrote: > In article <B68F2A37.47AD%lists@jumpinternet.com>, lists@jumpinternet.com > (Team JUMP) wrote: > >> $num=count($bannedwords); >> for($i=0;$i<$num-1;$i++) >> { >> $string = >> eregi_replace("\b$bannedwords[$i]\b","[censored]",$string); >> } >> >> >> For whatever reason, no word in $bannedwords will match in the string.
