parse_str Parses the string into variables &reftitle.description; voidparse_str stringstring arrayresult Parses string as if it were the query string passed via a URL and sets variables in the current scope (or in the array if result is provided). &reftitle.parameters; string The input string. result If the second parameter result is present, variables are stored in this variable as array elements instead. Using this function without the result parameter is highly DISCOURAGED and DEPRECATED as of PHP 7.2. As of PHP 8.0.0, the result parameter is mandatory. &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; parse_str() is affected by the max_input_vars directive. Exceeding this limit triggers an E_WARNING, and any variables beyond the limit are not added to the result array. The default is 1000; adjust max_input_vars as needed. All variables created (or values returned into array if second parameter is set) are already urldecoded. To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on variables from external sources. &reftitle.seealso; parse_url pathinfo http_build_query urldecode
