檢查文件類型使用php scandir不工作

Question

我使用這個波紋管php來檢查文件保存在數據庫中的種類，但它顯示一切爲文件夾，請我不知道是什麼問題。

<?php 
$path = dirname(__FILE__); 
$sub_folder = scandir($path); 
$num = count($sub_folder); 
//$jailchillink This is the name of file saved in database replaced width index.php 
    if(is_file($path.'\\'.index.php)){ $codetype = 'file';} 
    else if(is_img($path.'\\'.index.php)){ $codetype = 'image';} 
    else{ $codetype = 'folder';}?> 

上面的代碼將輸出folder

Answer 1

<?php 
    $path = dirname(__FILE__); 
    $sub_folder = scandir($path); 
    $num = count($sub_folder); 
    //$jailchillink This is the name of file saved in database replaced width index.php 
    if(is_file($path.'\\'.'index.php')){ 
    echo $codetype = 'file'; 
    }else if(is_img($path.'\\'.'index.php')){ 
    echo $codetype = 'image'; 
    }else{ 
    echo $codetype = 'folder'; 
    } 
?> 

現在的輸出爲file。只需在index.php左右添加'即可。
