Question

I have problem with php’s preg_match.I want to make something like this :
When someone on forum post someones username (example: @Username text..) to do the mysql query to insert notification to database.

I’ve made this code :

<?php 
$this = mysql_query("SELECT id,username FROM users");
while($the = mysql_fetch_array($this)){
if(preg_match("/^@".$the['username']."/",$form_text)){
 mysql_query("INSERT INTO notifications (num,who) VALUES ('$forum_id','".$the['username']."')");
}    
?>

But something is not working.How can i fix it ?
Thanks.

Answer 1

Try and use:

if (strpos( $form_text , $the['username'] ) !== false)

Hope this helps.
