What are the potential performance implications of using serialize/unserialize in PHP for storing data in a database?

Using serialize/unserialize in PHP for storing data in a database can lead to performance issues because the serialized data cannot be easily queried or indexed. This can result in slower retrieval times and increased resource usage. To solve this issue, consider storing the data in a structured format such as JSON or using separate columns for each piece of data. 

// Example of storing data in a structured format (JSON)
$data = ['key1' => 'value1', 'key2' => 'value2'];
$json_data = json_encode($data);
// Store $json_data in the database

// Example of using separate columns for each piece of data
$key1 = 'value1';
$key2 = 'value2';
// Store $key1 and $key2 in separate columns in the database
