如何循环$ _FILES？ [英] How to loop through $_FILES?

问题描述

我想在$ _FILES []数组中添加循环。我尝试了 $ count = count（$ _ FILES ['files'] [name]），然后为它添加循环（$ i = 0; $ i <= $ count; $ i ++），但它没有给我所需的输出。

我只想从用户正在上传的文件中添加循环，现在它正在计算表单中可用的所有文件。

请告诉我一种方法，只计算上传的文件并循环播放。

解决方案循环 $ _ FILES 数组并使用<$ c

$ $ $ codeount $（$ _ FILES）$ c $ [$ name]] ['files']）
for（$ i = 0; $ i <= $ count; $ i ++）{
if（$ _FILES ['files'] [$ i] ['size'] ）
echo $ _FILES ['files'] [$ i] ['name']。\\\
;
}

更容易的是使用foreach循环：

  foreach（$ _ FILES ['files'] as $ file）{
 if（$ file ['size']）
 echo $文件[ '名称'] \\\
。 
} 
  

I want to add loop around $_FILES[] array. I tried $count= count($_FILES['files'][name]) and then add loop around it for($i=0; $i<=$count; $i++), but it is not giving me desired output.

I want add to loop only from the files that the User is uploading, Right now it is counting all of the 'files' available in the form.

Kindly tell me a way to count only the uploaded files and loop through them.

解决方案

Loop ever the $_FILES array and use the ['name'] inside the iteration:

$count = count($_FILES['files'])
for($i=0; $i<=$count; $i++) {
  if ($_FILES['files'][$i]['size'])
    echo $_FILES['files'][$i]['name']."\n";
}

Even easier is to use a foreach loop:

foreach($_FILES['files'] as $file) {
  if($file['size'])
    echo $file['name']."\n";
}
