php-提取数组值的问题

我正在

$postdata

变量中获取所有HTML post值

$postdata = $this->input->post();
unset($postdata['submit']);
unset($postdata['valve_no']);

$postdata的输出

：

Array ( 
    [1] => Array ( 
        [0] => BH123 
        [1] => H89 
    ) 
    [2] => Array ( 
        [0] => BH123 
        [1] => H89 
    ) 
    [3] => Array ( 
        [0] => BH123 
        [1] => H89 
    ) 
    [4] => Array ( 
        [0] => BH123 
    )
)


$valve_no=$this->input->post('valve_no');

$valve\u no

的输出：

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

接下来，我尝试合并两个数组

foreach($postdata as $key => $val) 
{
    $dataSet[] = array ('valve_no'=>$valve_no[$key-1],$postdata[$key]);
} 
print_r($dataSet);

$dataSet的输出

：

Array ( 
    [0] => Array ( 
        [valve_no] => 1 
        [0] => Array ( 
            [0] => BH123 
            [1] => H89 
        ) 
    ) 
    [1] => Array ( 
        [valve_no] => 2 
        [0] => Array ( 
            [0] => BH123 
            [1] => H89 
        ) 
    ) 
    [2] => Array ( 
        [valve_no] => 3 
        [0] => Array ( 
            [0] => BH123 
            [1] => H89 
        ) 
    ) 
    [3] => Array ( 
        [valve_no] => 4 
        [0] => Array ( 
            [0] => BH123 
        ) 
    ) 
)

我期望的输出如下：

Array ( 
        [0] => Array ( 
            [valve_no] => 1 
            [1] => BH123 
            [2] => H89 
        ) 
        [1] => Array ( 
            [valve_no] => 2 
            [1] => BH123 
            [2] => H89 
        ) 
        [2] => Array ( 
            [valve_no] => 3 
            [1] => BH123 
            [2] => H89 
        ) 
        [3] => Array ( 
            [valve_no] => 4 
            [1] => BH123 
        ) 
    ) 
)

正如您在预期输出中看到的，我想提取子数组，需要从

[1]

开始，而不是从

[0]

开始

提前感谢。

只需更改

foreach（）

如下代码：（根据您的评论）

输出：

注意：如果

$postdata

子数组索引不是以0,1,2开头。。。你仍然希望他们从1,2开始，。。。在您的结果中，然后执行以下操作：

foreach($postdata as $key => $val) 
{
    
    $dataSet[$key-1]['valve_no'] = $valve_no[$key-1];
    $srNo = 1;
    foreach($val as $v){
        $dataSet[$key-1][$srNo] =$v;
        $srNo++;
    }
}

输出：

谢谢您的回答。让我来实施并让你知道。@你好，很高兴帮助你

foreach($postdata as $key => $val) 
{
    
    $dataSet[$key-1]['valve_no'] = $valve_no[$key-1];
    $srNo = 1;
    foreach($val as $v){
        $dataSet[$key-1][$srNo] =$v;
        $srNo++;
    }
}
