<?php
$arr = array(
    array('2933' => array(
        'document_id' => 1,
        'file_name' => 'a',
        'file_type' => 0,
    )),
    array('2934' => array(
        'document_id' => 1,
        'file_name' => 'a',
        'file_type' => 0,
    )),
    array('2935' => array(
        'document_id' => 1,
        'file_name' => 'a',
        'file_type' => 0,
    )),
);

var_dump($arr);

$result = array();
foreach($arr as $k=>$v){
    foreach($v as $kk=>$vv){
        $result[] = $vv;
    }
}

var_dump($result);

$a = array (
  array(2933 => array('document_id' => '2933')),
  array(2933 => array('document_id' => '2933')),
  array(2933 => array('document_id' => '2933')),
);
print_r($a);
array_walk($a, function(&$v) {$v = current($v);});
print_r($a);

处理前
Array
(
    [0] => Array
        (
            [2933] => Array
                (
                    [document_id] => 2933
                )

        )

    [1] => Array
        (
            [2933] => Array
                (
                    [document_id] => 2933
                )

        )

    [2] => Array
        (
            [2933] => Array
                (
                    [document_id] => 2933
                )

        )

)
处理后
Array
(
    [0] => Array
        (
            [document_id] => 2933
        )

    [1] => Array
        (
            [document_id] => 2933
        )

    [2] => Array
        (
            [document_id] => 2933
        )

)
