How to Combine Two Arrays Using `array_combine()` in PHP?

Combining Two Arrays with array_combine()

To efficiently map the values of one array as the keys of another, consider utilizing the built-in array_combine() function. It takes two arrays as arguments. The first array specifies the keys, and the second array contains the corresponding values.

Example:

Given two arrays, 'A' and 'B', let's demonstrate how to combine them:

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

Expected Output:

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

Code:

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

Advantages:

• Concise: array_combine() provides a concise one-line solution.
• Type Safety: It verifies that the input arrays have compatible types for keys and values.

Alternatives:

You can also use loops to accomplish this task, but array_combine() offers the most efficient and readable approach.
