How can the use of serialize() and unserialize() in PHP affect data storage and retrieval efficiency?

Using serialize() and unserialize() in PHP can affect data storage and retrieval efficiency because serialized data takes up more space compared to its original form. This can lead to increased storage requirements and slower data retrieval times. To mitigate this issue, consider using a more efficient data storage format or optimizing the serialization process.

// Example of using JSON encoding/decoding for more efficient data storage and retrieval
$data = ["key1" => "value1", "key2" => "value2"];

// Serialize data using JSON encoding
$serializedData = json_encode($data);

// Store serialized data in a file or database

// Retrieve serialized data
$retrievedData = json_decode($serializedData, true);

// Use retrieved data as needed
