How can the serialize() and unserialize() functions be utilized to store and retrieve array data in PHP?

To store and retrieve array data in PHP, the serialize() function can be used to convert an array into a string that can be stored in a database or file. To retrieve the array data, the unserialize() function can be used to convert the serialized string back into an array.

// Storing array data
$array = ['apple', 'banana', 'cherry'];
$serializedArray = serialize($array);
// Save $serializedArray to database or file

// Retrieving array data
// Retrieve $serializedArray from database or file
$retrievedArray = unserialize($serializedArray);
print_r($retrievedArray);
