php - mkdir() 跳过 foreach 函数中的第一个文件

Question

我有一个脚本可以读取 URL-Image-List 并将图像保存在基于 URL 的文件夹中。

这是我的脚本:

// Open the URL and save each line in a array
$file = fopen("http://www.edem.de/php/imglist.ashx","r");
$fileArray = array();
while (($line = fgetss($file)) !== false) {
    $fileArray[] = $line;
}

// Sort the array
array_multisort(array_values($fileArray), SORT_NUMERIC , array_keys($fileArray), SORT_NUMERIC , $fileArray);

// Start the iteration for saving each image
foreach ($fileArray as $url) {

    // Explode URL for folder and image name
    $urlpath = parse_url($url, PHP_URL_PATH);
    $dataend = explode("/", $urlpath);
    $ending = $dataend[5];
    $folder = $dataend[3];

    // delete "_" and "whitespace"
    $folder = strtr($folder, "_", " ");
    $folder = preg_replace('/\s+/', '', $folder);
    $ending = strtr($ending, "_", " ");
    $ending = preg_replace('/\s+/', '', $ending);

    // Check if folder exist. If yes -> go on with path. If no -> create folder
    if (!file_exists("Bilder/$folder/")) {
        $imgpath = mkdir("Bilder/$folder/", 0777, true);
        //I THINK THE MISTAKE IS HERE
    }
    else {
        $imgpath = ('Bilder/' .$folder. '/');
    }

    // save the path and the image name in a variable
    $savepath = $imgpath . $ending;

    // Test echo
    echo ("The image <strong>$ending</strong> is saved in the folder <strong>$savepath</strong>. The file should be in the folder <strong>$folder</strong><br><br>");    

    //Connect and save images
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $rawdata=curl_exec ($ch);
    curl_close ($ch);

    $fp = fopen(''.$savepath.'','w');
    fwrite($fp, $rawdata);
    fclose($fp);
}

每个文件夹应该包含一些图像。但是:当必须创建文件夹时，他创建了这个文件夹，但将第一个图像保存在根目录中而不是这个文件夹中。

示例回显 文件夹已创建，但第一张图像未保存在此新文件夹中。以下图像也属于此文件夹，已正确保存。

我没有收到任何错误。

在第一种情况下，您将其存储为 true 或 false。更改以下内容:

// Check if folder exist. If yes -> go on with path. If no -> create folder
if (!file_exists("Bilder/$folder/")) {
    $imgpath = mkdir("Bilder/$folder/", 0777, true);
    //I THINK THE MISTAKE IS HERE
}
else {
    $imgpath = ('Bilder/' .$folder. '/');
}

收件人:

// Check if folder exist. If yes -> go on with path. If no -> create folder
if (!file_exists("Bilder/$folder/")) {
    mkdir("Bilder/$folder/", 0777, true);
}
$imgpath = ('Bilder/' .$folder. '/');
