In PHP, how do I compare arrays with PHP 8+ features?

In PHP 8 and later versions, you can compare arrays using various built-in functions and operators. The comparison of arrays can be done simply by using operators or functions like `array_diff()`, `array_intersect()`, `==`, and `===` for deeper comparisons. This allows you to determine the differences or similarities between arrays efficiently.

Here is an example that demonstrates how to use array comparison with PHP 8 features:

<?php $array1 = ['apple', 'banana', 'cherry']; $array2 = ['apple', 'banana', 'cherry', 'date']; $array3 = ['apple', 'banana', 'cherry']; // Comparing arrays if ($array1 == $array3) { echo "Array 1 is equal to Array 3\n"; } else { echo "Array 1 is not equal to Array 3\n"; } // Using array_diff to find differences $differences = array_diff($array2, $array1); echo "Different elements between Array 2 and Array 1: " . implode(", ", $differences) . "\n"; // Using array_intersect to find common elements $common = array_intersect($array1, $array2); echo "Common elements in Array 1 and Array 2: " . implode(", ", $common) . "\n"; ?>
