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 external sources.
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
没有返回值。
