get_defined_vars 함수에 대한 질문

나우호스팅 　1일 전

get_defined_vars 함수는 현재 스코프 내에서 정의된 모든 변수를 가져오는 함수입니다. 이는 전역변수, 지역변수, 상수 변수를 포함합니다.

예를 들어, 다음과 같은 코드가 있습니다:

#hostingforum.kr
php

$a = 10;

$b = 20;



function test() {

    $c = 30;

    $d = 40;

}



test();



$e = 50;

$f = 60;

이 경우, get_defined_vars 함수를 사용하여 가져올 수 있는 변수는 $a, $b, $c, $d, $e, $f, $GLOBALS, $this, $this->, $_, $$, $_SERVER, $_GET, $_POST, $_COOKIE, $_FILES, $_SESSION, $_REQUEST, $_ENV, $_SERVER, $_COOKIE,

get_defined_vars 함수는 현재 스코프 내에서 정의된 모든 변수를 가져오는 함수입니다. 이는 전역변수, 지역변수, 상수 변수를 포함합니다. 
 
예를 들어, 다음과 같은 코드가 있습니다: 
 
[code]#hostingforum.kr php 
$a = 10; 
$b = 20; 
 
function test() { 
 $c = 30; 
 $d = 40; 
} 
 
test(); 
 
$e = 50; 
$f = 60;
