Re: [PHP] vertical word match SOLUTION From: 'Joe Rice' (riceja <email protected>)

I can't take full credit for this. i asked a fellow perl
programmer and he muttered the words, "why bother
searching for newlines and spaces". so, now searching
for any layout of the word will work.

$answer = "hello\na\np\np\nl\ne\n"; /*from textarea in form*/
/* replace all whitespace and newlines with nothing */
$tempanswer = preg_replace("/\s*|\n*/","",$answer);
$word = "apple";
/* match on the new condensed answer */
preg_match("/".$word."/i",$tempanswer,$match)

and this works for "red apple" as well.

thanks,
joe
