In PHP, how do I compare arrays in vanilla PHP?

In vanilla PHP, you can compare arrays using various functions depending on your requirements. For example, you can use `array_diff()`, `array_intersect()`, or use the comparison operators. Below is a simple example showcasing how to compare arrays in PHP.

<?php $array1 = [1, 2, 3, 4, 5]; $array2 = [4, 5, 6, 7, 8]; // Finding values present in $array1 but not in $array2 $diff = array_diff($array1, $array2); echo "Values in array1 but not in array2: "; print_r($diff); // Finding values present in both arrays $intersect = array_intersect($array1, $array2); echo "Values present in both arrays: "; print_r($intersect); ?>
