<?php // Example of hashing an array in PHP using the built-in hash function function hashArray($array) { // Serialize the array to maintain order and structure $serializedArray = serialize($array); // Generate a hash using SHA-256 $hash = hash('sha256', $serializedArray); return $hash; } // Sample array $sampleArray = [ 'name' => 'John Doe', 'email' => 'john@example.com', 'roles' => ['admin', 'editor'] ]; // Hash the array $hashedValue = hashArray($sampleArray); echo "Hashed Value: " . $hashedValue; ?>
