parse_str

Description

void parse_str ( string str [, array arr])

Parses str as if it were the query string passed via a URL and sets variables in the current scope. If the second parameter arr is present, variables are stored in this variable as array elements instead.

注: Support for the optional second parameter was added in PHP 4.0.3.

注: 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 outside of PHP.
