Php? $ _ REQUEST
 "; Var_dump ($ _ REQUEST); // The content does not contain 'foo' or 'bar'?>

$ _ REQUEST? HTTP Request variables indicate that $ _ GET, $ _ POST, and $ _ COOKIE arrays are included by default.
Var_dump ($ _ REQUEST); // The content does not contain 'foo' or 'bar '?


Reply to discussion (solution)

$ _ REQUEST, $ _ GET, and $ _ POST are all input data.
The value assigned in the code is not counted.

This test tells us that the request is an independent variable initialized by php and is not read from the get or post variable in real time.
