Question

Array
(
[selectCat1] => 'somevalue'
[selectSubCat1] => 'somevalue'
[heading1] => 'somevalue'
[filename1] => 'somevalue'
[orderBox1] => 'somevalue'
[selectCat3] => 'somevalue'
[selectSubCat3] => 'somevalue'
[heading3] =>  'somevalue'
[filename3] => 'somevalue'
[orderBox3] => 'somevalue'
[selectCat4] => 'somevalue'
[selectSubCat4] => 'somevalue'
[heading4] => 'somevalue'
[filename4] => 'somevalue'
[orderBox4] =>  'somevalue'
[selectCat5] => 'somevalue'
[selectSubCat5] => 'somevalue'
[heading5] => 'somevalue'
[filename5] => 'somevalue'
[orderBox5] => 'somevalue'
[selectCat6] => 'somevalue'
[selectSubCat6] => 'somevalue'
[heading6] => 'somevalue'
[filename6] => 'somevalue'
[orderBox6] => 'somevalue'
[selectCat7] => 'somevalue'
[selectSubCat7] => 'somevalue'
[heading7] => 'somevalue'
[filename7] => 'somevalue'
[orderBox7] => 'somevalue'

）

在[selectCat1]，[selectSubCat1]，[heading1]，[filename1]，[orderBox1]的数组值中需要插入一行DB表，[selectCat3]，[selectSubCat3]，[heading3] ，[filename3]，[orderBox3]在另一行。

我不能在1到7的范围内使用for循环，因为在1到7中应该忽略一些键，就像在这种情况下键2被忽略一样。

我尝试使用以下代码...

end($form_data); //$form_data is above array         
$key = key($form_data);  
$last_entry_no= substr($key,8); //to get the last key number
$count = count($form_data);
$rowsToInsert = $count/5;
for($i=1; $i<=$rowsToInsert; $i++)
{
  foreach ($form_data as $key => $value) {
   echo $key.'<br>';
  }
}

这不起作用。请帮帮我这个

尝试这样的事情：

$group = [];

foreach($array as $key => $value){
    $i   = substr($key, -1);
    $key = rtrim($key, $i);

    if(!isset($group[$i])){
        $group[$i] = [];
    }

    $group[$i][$key] = $value;
}

在$group数组的每个元素中，您将获得索引键组的键值对。
