How Can I Merge $_POST and $_FILES Arrays by Index for Efficient Data Handling?

Associating Array Elements for Comprehensive Data Management

Given two arrays, one derived from $_POST and the other from $_FILES, the goal is to combine them such that each element in one array is associated with the corresponding element in the other based on their indexes. The desired outcome is a new array with each element being an array containing all the data from both the original arrays.

The following is an alternative approach to achieve this using the array_replace_recursive function:

$newArr = array();
foreach ($array1 as $key => $value) {
  $newArr[$key] = array_replace_recursive($value, array_values($array2)[$key]);
}

Explanation:

• Loop through the original array.
• For each element in the loop, create a new array using array_replace_recursive.
• The array_values function is used to extract values from the second array based on the index of the current element.
• By using array_replace_recursive, we merge the elements into a single array, effectively associating them.
