删除所有具有特定条件的数组值

Question

我得到波纹管数组输出，我想删除仅具有[name] =>和[size] => 0数组。

当前数组：

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

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

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

    [3] => Array
        (
            [name] => Penguins.jpg
            [type] => image/jpeg
            [tmp_name] => /tmp/phpozs13E
            [error] => 0
            [size] => 777835
        )

    [4] => Array
        (
            [name] => Tulips.jpg
            [type] => image/jpeg
            [tmp_name] => /tmp/phpq66c41
            [error] => 0
            [size] => 620888
        )

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

)

我想要这个输出

Array
(
    [0] => Array
        (
            [name] => Penguins.jpg
            [type] => image/jpeg
            [tmp_name] => /tmp/phpozs13E
            [error] => 0
            [size] => 777835
        )

    [1] => Array
        (
            [name] => Tulips.jpg
            [type] => image/jpeg
            [tmp_name] => /tmp/phpq66c41
            [error] => 0
            [size] => 620888
        )
)

比这更简单； 您希望文件上传没有错误； 即

$results = array_filter($_FILES, function($file) {
    return $file['error'] === 0;
});
