Question

下面显示的是我在表单中发布的数据。由于我使用了多形式方法，因此我将发布的数据作为数组。我想将每个值保存到数据库中，即1,2,3.etc，因为它是属性“since_value”value。我怎么只得到这个值作为数组呢？

Array ( 

   [0] => Array ( [some_value] => Array ( [0] => 1 ) ) 
   [1] => Array ( [some_value] => Array ( [0] => 2 ) )
   [2] => Array ( [some_value] => Array ( [0] => 3 ) ) 
   [3] => Array ( [some_value] => Array ( [0] => 4 ) ) 
   [4] => Array ( [some_value] => Array ( [0] => 5 ) ) 
   [5] => Array ( [some_value] => Array ( [0] => 6 ) ) 
   [6] => Array ( [some_value] => Array ( [0] => 7 ) )

 )

我想让它像

 Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 )

我将如何做？

我试过

  $x=implode('',$array);

但是它给了我一个数组到字符串的转换错误。

这样做

<?php

$arr=Array (

    0 => Array ( 'some_value' => Array ( 0 => 1 ) ),
    1 => Array ( 'some_value' => Array ( 0 => 2 ) ),
    2 => Array ( 'some_value' => Array ( 0 => 3 ) ),
    3 => Array ( 'some_value' => Array ( 0 => 4 ) ),
    4 => Array ( 'some_value' => Array ( 0 => 5 ) ),
    5 => Array ( 'some_value' => Array ( 0 => 6 ) ),
    6 => Array ( 'some_value' => Array ( 0 => 7 ) )

);
    $new_arr= array();
    foreach($arr as $arr1)
    {
        foreach($arr1['some_value'] as $v){
        $new_arr[]=$v;
        }
    }

    print_r($new_arr);

使用单一foreach

$new_arr= array();
foreach($arr as $k=>$arr1)
{
    $new_arr[]=$arr1['some_value'][0];
}

print_r($new_arr);

<?php

$data = array(
    array('some_value' => array(1) ),
    array('some_value' => array(2) ),
    array('some_value' => array(3) ),
    array('some_value' => array(4) ),
    array('some_value' => array(5) ),
    array('some_value' => array(6) ),
    array('some_value' => array(7) ),
);

$output = array();
foreach($data as $k => $v)
{
    $output[$k] = $v['some_value'][0];
}

输出：

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
)

试试这个：

function array_flatten($array) {

   $return = array();
   foreach ($array as $key => $value) {
       if (is_array($value)){ $return = array_merge($return, array_flatten($value));}
       else {$return[$key] = $value;}
   }
   return $return;

}

$array  = array ( 
           array ( "some_value" => array ( 1 ) ), 
           array ( "some_value" => array ( 2 ) ),
           array ( "some_value" => array ( 3 ) ),
           array ( "some_value" => array ( 4 ) ), 
           array ( "some_value" => array ( 5 ) ),
           array ( "some_value" => array ( 6 ) ),
           array ( "some_value" => array ( 7 ) )
        );
$result = array_flatten($array);

echo "<pre>";
print_r($result);

输出：

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
)
