制作目录时遇到问题。错误： this is the error

Answer 1

因为目录用户

中没有文件

file_exists - 检查文件或目录是否存在且

is_dir - 判断文件名是否为目录

  if (is_dir("path") === true ){
                echo "DIRECTORY: ".$entry."\n";
            }

或

$filename = '/path/foo.txt';

if (file_exists($filename)) {
    echo "The file $filename exists";
}

Answer 2

mkdir( $dirPath, 0755, true );

第三个参数也会以递归方式创建包含目录。

Answer 3

mkdir()有第三个参数$recursive，它将确保存在完整路径。替换这个：

$result = mkdir($dirPath, 0755);

使用：

$result = mkdir($dirPath, 0755, true);

它应该可以正常工作。
