How Can I Easily Merge Two Arrays into Key-Value Pairs in PHP?

Merge Two Arrays as Key Value Pairs with Ease in PHP

Merging two arrays to create key-value pairs is a common task in PHP development. While manual looping and array manipulation may suffice, a more efficient and elegant solution exists: array_combine().

This built-in function takes two arrays as input and creates a new array with the values of the first array as keys and the values of the second array as the corresponding values. The syntax is straightforward:

$merged_array = array_combine($array_with_keys, $array_with_values);

Consider the following example:

$keys = ['apple', 'banana', 'orange'];
$values = [1, 2, 3];

$merged_array = array_combine($keys, $values);

After execution, $merged_array would look like this:

Array
(
    [apple] => 1
    [banana] => 2
    [orange] => 3
)

As you can see, array_combine() seamlessly transforms the two arrays into a key-value pair structure. By leveraging its power, you can effortlessly achieve this common operation in a concise and efficient manner.
