$_GET -- $HTTP_GET_VARS [deprecated]HTTP GET variables

설명

An associative array of variables passed to the current script via the URL parameters.

$HTTP_GET_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_GET_VARS and $_GET are different variables and that PHP handles them as such)

주의

Note:

이는 '자동전역' 변수입니다. 스크립트의 모든 영역에서 사용할 수 있습니다. 함수나 메쏘드 안에서 접근하기 위해서 global $variable;를 할 필요가 없습니다.

Note:

The GET variables are passed through urldecode().

<?php
// It is important to sanitize
// input! Otherwise, a bad actor
// could enter '<script src="evilscript.js"></script>'
// in a URL parameter. Assuming you echo it, this
// would inject scripts in an XSS attack.
//
// The solution:
$NAME = $_GET['NAME'];
// Bad:
echo $NAME;
// that one is vulnerable to XSS
// Good:
echo htmlspecialchars($NAME);
// Sanitizes input thoroughly.
