problem encountered with stristr-based function

Posted by "George Pitcher" on 01/20/06 16:44


I'm having a problem with the following function:

function terms($term,$field){
if(!stristr($term, $field) === FALSE) {
$output = str_replace($term, "<b>".$term."</b>", $field);
} elseif(!stristr(strtolower($term), $field) === FALSE) {
$output = str_replace(strtolower($term),
"<b>".strtolower($term)."</b>", $field);
} elseif(!stristr(strtoupper($term), $field) === FALSE) {
$output = str_replace(strtoupper($term),
"<b>".strtoupper($term)."</b>", $field);
} elseif(!stristr(ucfirst($term), $field) === FALSE) {
$output = str_replace(ucfirst($term), "<b>".ucfirst($term)."</b>",
} else {
$output = $field;
return $output;
I'm not comfortable enough with regex etc, so tried it my way, but no joy.

For info, I am trying to highlight search terms in results.

Any suggestions?
