如何迭代上传的图像文件

Question

I want to use foreach() to move image files into a folder and print imageupload name, tmp_name and so on. I am working on zend.

Input array:

 Array
(
    [imageUpload] => Array
        (
            [name] => P_20170224_134956_BF.jpg
            [type] => image/jpeg
            [tmp_name] => C:\xampp\tmp\phpBCB0.tmp
            [error] => 0
            [size] => 1057039
        )

    [imageUpload1] => Array
        (
            [name] => P_20170308_135054_BF.jpg
            [type] => image/jpeg
            [tmp_name] => C:\xampp\tmp\phpBCD0.tmp
            [error] => 0
            [size] => 1365444
        )

    [imageUpload2] => Array
        (
            [name] => 
            [type] => 
            [tmp_name] => 
            [error] => 4
            [size] => 0
        )

)

Code:

$data = array_merge_recursive(
    $request->getPost()->toArray(),
    $request->getFiles()->toArray()
);
// echo'<pre>';print_r($data); 

$array = array_slice($data, 2);  
print_r($array); 
foreach($array as $files)
{ 
    foreach ($files as $file) {
        print_r($files); 
        $destination  = "public/img/".$file['name']; 
        $file_name    = $file['tmp_name'];
        move_uploaded_file($file_name,$destination);
        $data = __DIR__.('/../../../../../public/img/').$file['name'];
    }
}

print_r() with error:

 Array
    (
        [name] => P_20170224_134956_BF.jpg
        [type] => image/jpeg
        [tmp_name] => C:\xampp\tmp\phpBCB0.tmp
        [error] => 0
        [size] => 1057039
    )
    <br />

        [tmp_name] => C:\xampp\tmp\phpBCB0.tmp
        [error] => 0

    )

Answer 1

You need not have two foreach for this scenario. Your $files is an associative array:

foreach($array as $files)
{ 
    $destination  = "public/img/".$files['name']; 
    $file_name    = $files['tmp_name'];
    move_uploaded_file($file_name,$destination);
    $data = __DIR__.('/../../../../../public/img/').$files['name'];
}

If you use foreach for $files, then it will still dig into your inner associative array, where you cannot use key.
