PHP require_once 全部代码相同，路径相同，文件名不相同的文件出现错误500

Question

<?php?>
header("content-type:text/html;charset=utf-8");
require_once 'config/config.php';
require_once 'functions/mysql.func.php';
$link = connect3();
$table = "student";
$totalRows = getTotalRows($link, $table);
$sumPage = ceil($totalRows/$pageSize);
$query = "select * from student";
$rows = fetchAll($link, $query);
print_r($rows);
?>
这是文件1代码，文件名profile.php，根目录下的，引用路径是没错的，路径前加上./也是报错HTTP ERROR 500，甚至把所有代码删除只留下
<?php
require_once 'config/1.php';
?>
引一个空的文件也报错HTTP ERROR 500



<?php
require_once '../functions/mysql.func.php';
require_once '../config/config.php';
header("content-type:text/html;charset=utf-8");
$link = connect3();
$page = $_GET['page']?$_GET['page']:1;
$pageSize = 5;
$offSet = ($page-1)*5;
$table = "student";
$totalRows = getTotalRows($link, $table);
$sumPage = ceil($totalRows/$pageSize);
$query = "select * from student";
$rows = fetchAll($link, $query);
?>
这是文件2的代码，文件名layout-index.php，在Student目录下，运行代码是正常的


<?php
$config = array(
    'host'=>'localhost',
    'user'=>'3hnyuta29i222',
    'password'=>'yijia888',
    'charset'=>'utf8',
    'dbName'=>'3hnyuta29i222'
);
define('DB_HOST','localhost');
define('DB_USER','3huyuta21i212');
define('DB_PWD','******');
define('DB_CHARSET','utf8');
define('DB_DBNAME','3huyuta21i212');

这是引用的config.php文件代码
