PHP Array_search won’t find an existing value

I'm trying to use array_search on a simple array :

          echo "<br> Search for : -".ucfirst(strtolower(trim($rowData[0][2]))).'-';    

here is the index of the value ( I know it but I want PHP to find it for me >< ):

          echo '<br>-'.$listMetiers[0].'-';     

Here is the full array :

          echo '<pre>';          print_r($listMetiers);          echo '</pre>';            $id_metier = array_search(ucfirst(strtolower(trim($rowData[0][2]))),$listMetiers);            if(!$id_metier)          {            echo ' NOT FOUND !<br>';            $id_metier = -666;          }          else          {            echo 'GOOD : '.$id_metier.'<br>';          }    

The value is in the array but array_search don't find it ! Look what I have when executing this code :

What is going on ?
