$HTTP_GET_VARS [deprecated]

(PHP 4 >= 4.1.0, PHP 5, PHP 7)

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


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)


버전 설명
4.1.0 Introduced $_GET that deprecated $HTTP_GET_VARS.


Example #1 $_GET example

echo 'Hello ' htmlspecialchars($_GET["name"]) . '!';

Assuming the user entered http://example.com/?name=Hannes

위 예제의 출력 예시:

Hello Hannes!



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


The GET variables are passed through urldecode().

// 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.
