preg_match expects its regex argument to be within a pair delimiters. So try: if ( ! preg_match(“#convert$#i”, $this->library_path)) { if ( ! preg_match(“#/$#i”, $this->library_path)) $this->library_path .= “https://stackoverflow.com/”; $this->library_path .= ‘convert’; } if (preg_match(“#gd2$#i”, $protocol)) { $protocol=”image_process_gd”; }
