生成的数组：

 array
   'first_name' => string 'sushil' (length=6)
   'last_name' => string 'asfasfaf' (length=8)
   'gen' => string 'Male' (length=4)
   'language' => string 'PHP' (length=3)
   'biodata' => string 'sfsafsaf hdffd ' (length=15)
   'hobbies' => 
    array
       0 => string 'gaming' (length=6)
       1 => string 'football' (length=8)
       2 => string 'cricket' (length=7)
   'academic_qualification' => string 'Bachelor' (length=8)

我想修改上面的步骤：

 //finds if child array exists. If exists interchange key and value and update value to '1'.
 array
  'gaming' => int 1
  'football' => int 1
  'cricket' => int 1

最后取消设置原始子数组并将修改后的子数组元素合并到父数组中。我期望的阵列形式：

 array
   'first_name' => string 'sushil' (length=6)
   'last_name' => string 'asfasfaf' (length=8)
   'gen' => string 'Male' (length=4)
   'language' => string 'PHP' (length=3)
   'biodata' => string 'sfsafsaf hdffd ' (length=15)
   'academic_qualification' => string 'Bachelor' (length=8)
   'gaming' => int 1
   'football' => int 1
   'cricket' => int 1

我试过跟随，但它不起作用：

 $submited_data = $_POST;
         var_dump($submited_data);
         foreach($submited_data as $value){  
            if(is_array($value)) {        //checks if array contains array.
                $a = array_flip($value);  //then interchange
                var_dump($a);
                foreach($a as $key=>$b){
                    $a[$key] = 1;         //update all value to '1'.      
                }
                array_push($submited_data,$a);    // here is the problem I cannot proceed to furthur step. Please help me. How to merge modified child array to parent array.
                var_dump($a);

            }
        }

谢谢。

我刚刚重写了你的代码。如果出现任何问题请告诉我！

<?php
    $submited_data = $_POST;
    foreach($submited_data as $key => $data)
    {
        if(is_array($data))
        {
            foreach($data as $sub_data)
            {
                $submited_data[$sub_data] = 1; 
            }
            unset($submitted_data[$key]);
        }
    }

假设$array是包含子数组的数组，

$mergedArray = [];

array_walk_recursive($array, function($a,$b) use (&$mergedArray) { $mergedArray[$b] = $a; }); 

echo '<pre>';
print_r($mergedArray);

检查数组是否包含子数组并在父数组中合并
