parse_str -- Parses the string into variables
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.
