 * You might think that parse_ini_file already exists and your right it does but this fixes the difference in version between
 * php 5.2 and php 5.3 where single quotes are left on on version 5.2 and removed on v5.3
 *
 * This function only exists as a work around for the change to the parse_ini_file function between php v5.2 and v5.3
 * In version 5.3 it does nothing and passes directly to parse_ini_file, in 5.2 it uses parse_ini_file and fixes the result to match that expected in 5.3
