What are some best practices for debugging PHP code, specifically when dealing with arrays and array_combine() function?

Issue: When using the array_combine() function in PHP to combine two arrays into a single associative array, it is important to ensure that the arrays have the same number of elements. Otherwise, it can lead to errors or unexpected behavior. To debug this issue, you can check the length of both arrays before using array_combine(). Code snippet: 

$array1 = [1, 2, 3];
$array2 = ['a', 'b', 'c'];

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