Mapping key value pair from char of array in laravel

<?php

$originalArray = ["a", "b", "c", "d"];
$mappingArray = ["apple", "banana", "cherry", "date"];

$characterMapping = [];

// Ensure both arrays have the same length
if (count($originalArray) == count($mappingArray)) {
    // Create a key-value pair mapping
    $characterMapping = array_combine($originalArray, $mappingArray);
}

// Display the result
echo "Character Mapping:\n";
print_r($characterMapping);

?>

Character Mapping:
Array
(
    [a] => apple
    [b] => banana
    [c] => cherry
    [d] => date
)
