PHP mkdir - 抛出错误“文件存在”

Question

我目前通过工作存折的部分iOS6的由团队通过教程在raywenderlich.com，并且我得到我的PHP以下错误：

警告：mkdir() [function.mkdir]：文件存在于第 26 行的 /xxx/xxx/xxx/xxx/Pass.php

警告：mkdir() [function.mkdir]：文件存在于第 26 行的 /xxx/xxx/xxx/xxx/Pass.php

警告：rmdir(/tmp/50c8d11c60538/..) [function.rmdir]：第 54 行 /xxx/xxx/xxx/xxx/Pass.php 中的目录不为空

我班上的代码如下：

class Pass
{
    private $workFolder = null;
    private $ID = null;

    var $content = null;
    var $passBundleFile = null;

    private function copySourceFolderFilesToWorkFolder($path)
    {
        // recurse over the contents and copy files
        $files = new RecursiveIteratorIterator(
                        new RecursiveDirectoryIterator($path),
                        RecursiveIteratorIterator::SELF_FIRST);

        foreach ($files as $name => $fileObject)
        {
            if (is_file($name) && substr($fileObject->getFileName(), 0, 1) != ".")
            {
                copy($name, $this->workFolder."/".str_replace($path."/", "",$name));
            }
            else if (is_dir($name))
            {
                mkdir($this->workFolder."/".str_replace($path."/", "",$name));
            }
        }
    }

    // delete all auto-generated files in the temp folder
    function cleanup()
    {
        // recurse over conrents and delete files
        $files = new RecursiveIteratorIterator(
                        new RecursiveDirectoryIterator($this->workFolder),
                        RecursiveIteratorIterator::CHILD_FIRST);

        foreach ($files as $name => $fileObject)
        {
            if (is_file($name))
            {
                unlink($name);
            }
            else if (is_dir($name))
            {
                rmdir($name);
            }
        }

        rmdir($this->workFolder);
    }

    function __construct($path)
    {
        assert(file_exists($path."/pass.json"));

        $this->ID = uniqid();

        $this->workFolder = sys_get_temp_dir()."/".$this->ID;
        mkdir($this->workFolder);
        assert(file_exists($this->workFolder));

        $this->copySourceFolderFilesToWorkFolder($path);

        $this->readPassFromJSONFile($this->workFolder."/pass.json");
    }

    // cleanup the temp folder on object destruction
    function __destruct()
    {
        $this->cleanup();
    }
}

并且正在实例化一个实例：

$coupon = new Pass("pass/source");

我曾尝试上传随本书提供的示例代码并得到相同的错误。

我已经在相关论坛上发布了这个，但是还没有人回复，我想在继续之前深入了解这个问题。

谢谢，尼克

您的第一个 if 测试是否为“.” 和 '..' 但它将是错误的并转到其他。和 '。' 和 '..' 是目录。因此它尝试创建一个名为“.”的目录，该目录已经存在。

if (is_file($name) && substr($fileObject->getFileName(), 0, 1) != ".")
        {
            copy($name, $this->workFolder."/".str_replace($path."/", "",$name));
        }
        else if (is_dir($name))
        {
            mkdir($this->workFolder."/".str_replace($path."/", "",$name));
        }

通过这样做修复：

if($name == '.' || $name == '..'){// ignore '.' and '..', but not hidden files
continue;
}
if (is_file($name))
            {
                copy($name, $this->workFolder."/".str_replace($path."/", "",$name));
            }
            else if (is_dir($name))
            {
                mkdir($this->workFolder."/".str_replace($path."/", "",$name));
            }
