runkit_function_redefine
(PECL runkit >= 0.7.0)
runkit_function_redefine — Replace a function definition with a new implementation
설명
bool runkit_function_redefine
( string
$funcname
, string $arglist
, string $code
)Note: 기본적으로 사용자 함수만 삭제하거나, 이름을 바꾸거나, 변경할 수 있습니다. 내장 함수를 덮어쓰려면 php.ini 파일에서 runkit.internal_override을 활성화하여야 합니다.

Here is another example with a parameter:
<?php
function hello_world($word) {
echo "Original Hello World: $word\n</br>";
}
$helloWorld = 'echo "Redefined Hello World: $word\n</br>";';
hello_world('test1');
runkit_function_redefine('hello_world', '$word', $helloWorld);
hello_world('test2');
?>
