PHP $ _FILES [＆＃39; name＆＃39;] [＆＃39; type＆＃39;]返回空值

Question

所以我尝试一次上传多个mp3文件，只上传了一个。{p>我做了一些跟踪，结果发现由于某种原因，某些文件类型返回空值，所以我认为结果是它们没有被上传。虽然我不太确定，但我的研究结果并不多，因为我现在还不确切知道要研究什么。

这是我上传多个mp3文件时返回的数组。

Array
(
    [name] => Array
        (
            [0] => a.mp3
            [1] => e.mp3
            [2] => s.mp3
        )

    [type] => Array
        (
            [0] => 
            [1] => audio/mp3
            [2] => 
        )

    [tmp_name] => Array
        (
            [0] => 
            [1] => /private/var/tmp/phpfqxWTx
            [2] => 
        )

    [error] => Array
        (
            [0] => 1
            [1] => 0
            [2] => 1
        )

    [size] => Array
        (
            [0] => 0
            [1] => 1908445
            [2] => 0
        )

)
