如何迭代PHP $ _FILES数组? [英] How can I iterate PHP $_FILES array?

问题描述

这可能是一个愚蠢的问题，但是PHP数组$ _FILES具有非常奇怪的格式，这是我以前从未使用过的格式.有人可以告诉我如何以理智的方式迭代此数组吗?我曾经迭代对象或对象，例如数组，但是这种格式对我来说很奇怪.有什么方法可以像对象数组那样迭代该数组吗?

This might be stupid question, but PHPs array $_FILES has very odd format, which I have never used before. Can somebody tell me how can I iterate this array in sane way ? I have used to iterate objects or object like arrays, but this format is very odd for me. Is there any way to iterate this array like object array?

( [attachments] => 
    Array ( 
        [name] => Array ( 
            [0] => test1.png 
            [1] => test2.png 
        ) 
        [type] => Array ( 
            [0] => image/png 
            [1] => image/png 
        ) 
        [tmp_name] => Array ( 
            [0] => /tmp/phpmFkEUe 
            [1] => /tmp/phpbLtZRw 
        )
        [error] => Array ( 
            [0] => 0 
            [1] => 0 
        ) 
        [size] => Array ( 
            [0] => 9855 
            [1] => 3002 
        ) 
    ) 
)

推荐答案

哇，这确实很奇怪，您是否在标记中使用<input type="file" name="attachments[]" />?如果您有能力使用唯一的name=进行更改，则不会有这种奇怪的格式...

Wow, that indeed is odd, are you using <input type="file" name="attachments[]" /> in your markup? If you could afford to change those using unique name=, you won't have that odd format...

要直接回答您的问题，请尝试:

To directly answer your question, try:

$len = count($_FILES['attachments']['name']);

for($i = 0; $i < $len; $i++) {
   $fileSize = $_FILES['attachments']['size'][$i];
   // change size to whatever key you need - error, tmp_name etc
}
