PHP判断文件是否被引入的方法get_included_files

<?php
// 本文件是 abc.php

include 'test1.php';
include_once 'test2.php';
require 'test3.php';
require_once 'test4.php';

$included_files = get_included_files();

foreach ($included_files as $filename) {
    echo "$filename\n";
}

?>

结果：

以上例程会输出：
abc.php
test1.php
test2.php
test3.php
test4.php
