What are some best practices for handling JSON data in PHP scripts?

When handling JSON data in PHP scripts, it's important to properly encode and decode the data to ensure compatibility and prevent errors. Use the json_encode() function to convert PHP data structures into JSON format, and json_decode() to convert JSON data back into PHP arrays or objects. Additionally, always validate JSON data before processing it to prevent security vulnerabilities. 

// Encode PHP array into JSON
$data = array("name" => "John", "age" => 30);
$json_data = json_encode($data);

// Decode JSON data into PHP array
$decoded_data = json_decode($json_data, true);

// Validate JSON data before processing
if (json_last_error() === JSON_ERROR_NONE) {
    // JSON data is valid, proceed with processing
    // ...
} else {
    // Handle invalid JSON data
    echo "Invalid JSON data";
}
