Array Search Not Working?

Hi, I have two arrays here that I have combined into a new array, as shown here: $from = explode("-", $from); $change = explode("-",$change); $new_array = array_combine($from,$change); I then tried reading it from a file and do string matches, trying to find out the "key" using the array_search of the individual array elements. I seem to have no such luck, even when I copied one of the elements after I do a print_r($new_array); Here is the code, foreach ($lines2 as $line_num => $line2) { $style_line_num = $line_num+3; if(preg_match("/^style/",$line2)) { if(preg_match("/inkscape:label/",$lines2[$style_line_num])) { $location = explode("=",$lines2[$style_line_num]); $location2 = substr($patient_location[1],1,-6); if(in_array($location2, $from)) { $key= array_search($location2,$new_array); //Find out the position of the index in the array echo "Key " . $key . "<br>"; //This only gives me a blank space after the word Key } } //end preg_match inkscape } //If preg_match style I looked at the example from http://php.net/manual/en/function.array-search..php, and looks like what I am trying to do here is possible, and yet, why am I not getting a proper key return? Thanks for your help. Alice _________________________________________________________________ Hotmail: Powerful Free email with security by Microsoft. http://clk.atdmt.com/GBL/go/201469230/direct/01/
