What functions can be used to convert arrays into a format suitable for storage in a database in PHP?

When storing arrays in a database in PHP, you need to convert the array into a format that can be easily stored and retrieved. One common way to do this is by serializing the array using the `serialize()` function before storing it in the database. When retrieving the data, you can use the `unserialize()` function to convert it back into an array. 

// Sample array to be stored in the database
$data = ['name' => 'John', 'age' => 30, 'city' => 'New York'];

// Serialize the array before storing in the database
$serializedData = serialize($data);

// Store $serializedData in the database

// Retrieve the serialized data from the database
// Assuming $serializedData is retrieved from the database
$retrievedData = unserialize($serializedData);

// $retrievedData will now contain the original array data
print_r($retrievedData);
