我写了一个自动加载器类。
但include_once函数不包含我需要的文件。
Cls.php（路径：CLS /）
<?php
class fileup{
function dup($a){
$x=strip_tags($a);
$d=__DIR__."/".$x.".cls.php";
echo $d; ///storage/emulated/legacy/htdocs/yeni/sinif/ayar.sinif.php
if(file_exists($d)){
include_once $d;
}else{
die($a." Class not found :(");
}
}
}
$dup=new fileup();
spl_autoload_register(array($dup,"dup"));
?>
Theme.cls.php主题类（路径：cls /）
<?php
include_once("cls.php");
$dup->dup("conf");
?>
Conf.cls.php站点配置类（路径：cls /）
<?php include_once("cls.php"); $dup->dup("db"); ?>
index.php（路径：/）
<?php
include_once("theme.cls.php");
?>
错误详情：
