parse_str

(PHP 4, PHP 5)

parse_str — Parses the string into variables

说明

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.

Note: 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.

Note: The magic_quotes_gpc setting affects the output of this function, as parse_str() uses the same mechanism that PHP uses to populate the $_GET, $_POST, etc. variables.

参数

str: The input string.
arr: If the second parameter arr is present, variables are stored in this variable as array elements instead.

返回值

无返回值。
