mkdir（）跳过foreach函数中的第一个文件

Question

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

这是我的剧本：

// 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);
}

每个文件夹应包含一些图像。 但是：当必须创建文件夹时，他会创建此文件夹，但将第一个图像保存在root中，而不是保存在此文件夹中。

示例回显 该文件夹已创建，但第一个图像不会保存在此新文件夹中。 以下图像也属于此文件夹，可以正确保存。

我没有错误。

Answer 1

$imgpath = mkdir(....

http://docs.php.net/mkdir说：

返回值

成功时返回TRUE，失败时返回FALSE。

Answer 2

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. '/');
}

要：

// 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. '/');

Answer 3

更改以下代码：

if (!file_exists("Bilder/$folder/")) {
    $imgpath = mkdir("Bilder/$folder/", 0777, true);
    //I THINK THE MISTAKE IS HERE
}
else {
    $imgpath = ('Bilder/' .$folder. '/');
}

为：

if (!is_dir("Bilder/$folder/")) {
    if( ! mkdir("Bilder/$folder/", 0777, true) ){
        continue; // continue = Jump to next. Alternative would be break; which breaks the loop. If it cant create the dir, then you cant upload the file. So I would personally use break; But continue atleast lets you try for all the files.
    }
    $imgpath = "Bilder/{$folder}/";
}

从mkdir手册中，该函数返回一个布尔值。如果目录已成功创建，则应为true。

  

bool mkdir（string $ pathname [，int $ mode = 0777 [，bool $ recursive = false [，resource $ context]]]）
