Using this function without the result parameter is highly DISCOURAGED and DEPRECATED as of PHP 7.2. &reftitle.returnvalues; &return.void; &reftitle.changelog; &Version; &Description; 8.0.0 result is no longer optional. 7.2.0 Usage of parse_str without a second parameter now emits an E_DEPRECATED notice. &reftitle.examples; ]]> Because variables in PHP can't have dots and spaces in their names, those are converted to underscores. Same applies to naming of respective key names in case of using this function with result parameter. ]]> &reftitle.notes; All variables created (or values returned into array if second parameter is set) are already urldecoded.
