拆分数组$ _FILES

Question

我有一个像这样在我的HTML表单一个共同的输入和两个文件输入多张：

div class="col-md-4"> 
    <div class="form-group"> 
     <label class="control-label col-md-3">Size</label> 
      <div class="col-md-9"> 
       <?php 
       $size = array(
         "type" => "text", 
         "name" => "size", 
         "id" => "size", 
         "class" => "form-control" 
         ); 
       echo form_input($size); 
       ?> 
       <span class="help-block"></span> 
      </div> 
      </div> 
     </div> 


<div class="col-md-6"> 
    <div class="form-group"> 
     <label class="control-label col-md-2">Image Container:</label> 
      <div class="col-md-10"> 
       <input type="file" multiple="" name="images_container[]" id="file_container" required="required"> 
       <p class="help-block"></p> 
      </div> 
    </div> 
</div> 

<div class="col-md-6"> 
    <div class="form-group"> 
     <label class="control-label col-md-2">Image If Coil Is Damage</label> 
      <div class="col-md-10"> 
       <input type="file" multiple="" name="images[]" id="files" > 
       <p class="help-block"></p> 
      </div> 
    </div> 
</div> 

我抢他们用ajax jquery的

$('#form').submit(function() { 
     $('#btnSave').text('saving...'); //change button text 
     $('#btnSave').attr('disabled', true); //set button disable 

     var url; 
     var fd = new FormData(); 
     var file_data = $('#files')[0].files; // for multiple files 
     var file_data_container = $('#file_container')[0].files; // for multiple files 

     for (var j = 0; j < file_data_container.length; j++) { 
      fd.append("file_container_" + j, file_data_container[j]); 
     } 

     for (var i = 0; i < file_data.length; i++) { 
      fd.append("file_coil" + i, file_data[i]); 
     } 

     var other_data = $(this).serializeArray(); 
     $.each(other_data, function (key, input) { 
      fd.append(input.name, input.value); 
     }); 
$.ajax({ 
      url: url, 
      type: "POST", 
      data: fd, 
      processData: false, 
      contentType: false, 
      dataType: "JSON", 
      success: function (data){} 

}); 

所以，$从阿贾克斯提交_FILES数组是这样的：

Array 
(
[file_container_0] => Array 
    (
     [name] => bonus.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php95B4.tmp 
     [error] => 0 
     [size] => 616252 
    ) 

[file_container_1] => Array 
    (
     [name] => coolas.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9613.tmp 
     [error] => 0 
     [size] => 641576 
    ) 

[file_container_2] => Array 
    (
     [name] => preview.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9633.tmp 
     [error] => 0 
     [size] => 474285 
    ) 

[file_coil0] => Array 
    (
     [name] => 1280x800.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9653.tmp 
     [error] => 0 
     [size] => 214172 
    ) 

[file_coil1] => Array 
    (
     [name] => 1280x960.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9674.tmp 
     [error] => 0 
     [size] => 261002 
    ) 

) 

我的问题是，我怎么可以拆分该数组这个数组分成两个数组。

第一个数组

Array 
(
[file_container_0] => Array 
    (
     [name] => bonus.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php95B4.tmp 
     [error] => 0 
     [size] => 616252 
    ) 

[file_container_1] => Array 
    (
     [name] => coolas.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9613.tmp 
     [error] => 0 
     [size] => 641576 
    ) 

[file_container_2] => Array 
    (
     [name] => preview.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9633.tmp 
     [error] => 0 
     [size] => 474285 
    ) 

) 

第二个数组

Array 
(
    [file_coil0] => Array 
    (
     [name] => 1280x800.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9653.tmp 
     [error] => 0 
     [size] => 214172 
    ) 

[file_coil1] => Array 
    (
     [name] => 1280x960.jpg 
     [type] => image/jpeg 
     [tmp_name] => D:\xampp\tmp\php9674.tmp 
     [error] => 0 
     [size] => 261002 
    ) 

) 

Answer 1

在索引位置检测子我们可以diffrenciate两个数组：

$file_container_array = array(); 
$file_coil_array = array(); 

$files_array = $_FILES; 
foreach($files_array as $key => $file) 
if (strpos($key, 'file_container') !== false) { 
    $file_container_array[] = $file; 
} else if(strpos($key, 'file_coil') !== false) { 
    $file_coil_array[] = $file; 
} 

print_r($file_container_array); 
print_r($file_coil_array); 

Answer 2

您可以采取的Advanta的type juggling GE：

$result = array(); 
foreach($_FILES as $key => $val) 
{ 
    $result[ substr($key,0,9)=='file_coil' ][$key] = $val; 
} 

现在$result[0]你都file_container值，并在$result[1]你有file_coil值。

也许你的数组长度是可变的，但如果它有一个固定的长度，你可以使用array_chunk代替：

$result = array_chunk($_FILES, 3, True);
