php - identical strings don't show up as a match

I'm trying to determine whether or not two strings match, and even though when I print them out, they're identical, it still says they don't match.  I tried to cast them both as strings, and I tried using '===' instead of '==', but neither solved the problem...

       if(preg_match("#^Availability:#", $test)) {
        //just to note: $test = "Availability: Lorem Ipsum";
        $nid = 1;
        $prep = explode("Availability:", $test);
        $orig = node_load($nid);
        print $prep[1];  //Prints Lorem Ipsum
        print($orig->title); //Prints Lorem Ipsum
        if((string)$orig->title	== (string)$prep[1]) { 
          print 'ok'; 
        } else { 
          print 'nope'; //Always prints nope

instead of print, try

Open in new window

and make sure there are no leading/trailing spaces in of of them.
You're not including the space after the colon in your explode() statement.  Therefore, $prep[1] = ' Lorem Ipsum', not 'Lorem Ipsum'.

You should try changing the explode statement to:
$prep = explode("Availability: ", $test);

When you "exploded" the string, you did so on "Availability:", but you still left the space between ":" and "Lorem". I believe you are comparing " Lorem Ipsum" to "Lorem Ipsum". Spaces count in string comparison.
