What are the potential pitfalls of using array_combine in PHP when working with multiple arrays?

When using array_combine in PHP with multiple arrays, a potential pitfall is that if the arrays have different lengths, it will result in a warning and the function will not work as expected. To solve this issue, you should ensure that the arrays being passed to array_combine have the same number of elements. 

$array1 = array('a', 'b', 'c');
$array2 = array(1, 2, 3);

if(count($array1) == count($array2)){
    $combinedArray = array_combine($array1, $array2);
    print_r($combinedArray);
} else {
    echo "Arrays must have the same number of elements";
}
