How Can I Merge Two Arrays While Preserving Index Alignment in PHP?

Creating a New Array with Elements from Two Existing Arrays

When working with data from $_POST and $_FILES, it is often necessary to associate elements from both arrays based on their indexes. This can be achieved by merging the arrays into a new array, ensuring that the elements are correctly aligned.

To resolve your issue with losing data during each loop iteration, consider using either of the following built-in array functions:

• array_merge_recursive: This function combines the elements of multiple arrays recursively. It preserves the keys of each array, allowing for deeper-level merges.
• array_replace_recursive: Similar to array_merge_recursive, this function also combines multiple arrays. However, it uses a slightly different merging logic, replacing existing values with new ones instead of concatenating them.

By using either of these functions, you can effectively merge the elements from $array1 and $array2 based on their indexes, creating a new array with the desired associations. The resulting array will have the structure:

[
  0 => [
    0 => 123,
