is_file（）和is_dir（）不起作用

Question

我正在寫一個文件哈希類，但我一開始就卡住了。

class fileHashing 
{ 
    private $start_path = '../../../test'; 
    private $log_path = '../../../test/log'; 
    private $log_file = 'fileHash.xyz'; 

    function __construct() 
    { 
     $this->open(); 
    } 

    private function open() { 
     $files_list = scandir($this->start_path); 
     print_r($files_list); 
     date_default_timezone_set('Europe/Rome'); 
     foreach ($files_list as $key => $element) { 
      if (is_file($element)) { 
       echo "FILE: " . $element . PHP_EOL; 

      } elseif (is_dir($element)) { 
       echo "DIR: " . $element . PHP_EOL; 
      } else { 
       echo "NONE: " . $element . PHP_EOL; 
      } 
     } 
    } 
} 

$a = new fileHashing(); 

返回：

Array 
(
    [0] => . 
    [1] => .. 
    [2] => fileupload.php 
    [3] => log 
    [4] => test1.php 
    [5] => tsconfig.json 
) 
DIR: . 
DIR: .. 
FILE: fileupload.php 
NONE: log 
NONE: test1.php 
NONE: tsconfig.json 

log是一個文件夾，它不承認它，既test1.php和tsconfig.json不確認文件。 我錯過了什麼scandir()/is_file()/is_dir()？

你還應該追加start_path到您的文件名中is_file和is_dir。可以這樣做

private function open() { 
    $files_list = scandir($this->start_path); 
    print_r($files_list); 
    date_default_timezone_set('Europe/Rome'); 
    foreach ($files_list as $key => $element) { 
     $file = $this->start_path . '/' . $element; 
     if (is_file($file)) { 
      echo "FILE: " . $element . PHP_EOL; 

     } elseif (is_dir($file)) { 
      echo "DIR: " . $element . PHP_EOL; 
     } else { 
      echo "NONE: " . $element . PHP_EOL; 
     } 
    } 
}

用這樣的方式： -

if (filetype($this->start_path . '/' . $element) == "dir") { 
    // dir 
}elseif(filetype($this->start_path . '/' . $element) == "file") { 
    // file 
} 
// or this way 
if (is_dir($this->start_path . '/' . $element)) { 
    // dir 
}elseif(is_file($this->start_path . '/' . $element)) { 
    // file 
}
