PHP parses query string into variable function parse_str ()

Instance

Parse the query string into the variable:

<?phpparse_str ("name=peter&age=43"); Echo $name. " <br> "; Echo $age;? >

Definition and usage

The Parse_str () function parses the query string into a variable.

Note: If the array parameter is not set, the variable set by the function overrides the already existing variable with the same name.

Note: The MAGIC_QUOTES_GPC setting in the php.ini file affects the output of the function. If enabled, the variable is converted by addslashes () before Parse_str () is resolved.
