How Can You Combine Two Arrays with Key-Value Pairs Using `array_combine()`?

Utilizing array_combine() to Merge Key-Value Arrays

The challenge of combining two arrays, assigning the values of one as keys for the other, can be effectively addressed using the array_combine() function. As suggested by the manual:

<code class="php">array array_combine(array $keys, array $values)</code>

"Creates an array by using the values from the keys array as keys and the values from the values array as the corresponding values."

Example:

Given the following arrays:

<code class="php">$array['A'] = ['cat', 'bat', 'hat', 'mat'];
$array['B'] = ['fur', 'ball', 'clothes', 'home'];</code>

To create an array C where A's values become keys and B's values become the associated values:

<code class="php">$array['C'] = array_combine($array['A'], $array['B']);</code>

Expected Output:

<code class="php">$array['C'] = [
    'cat' => 'fur',
    'bat' => 'ball',
    'hat' => 'clothes',
    'mat' => 'home',
];</code>

While other methods involving loops can achieve the same result, array_combine() provides a straightforward and concise solution for this specific task.
