What potential pitfalls should be considered when storing and manipulating JSON data in PHP, especially in the context of Joomla repeatable fields?

When storing and manipulating JSON data in PHP, especially in the context of Joomla repeatable fields, it is important to consider potential pitfalls such as data validation, security vulnerabilities, and data integrity issues. To mitigate these risks, ensure that input data is properly sanitized and validated before storing it as JSON. Additionally, implement proper error handling mechanisms to prevent data corruption and security breaches. 

// Example code snippet for sanitizing and validating JSON data before storing it
$input_data = $_POST['json_data'];

// Sanitize and validate input data
$sanitized_data = filter_var($input_data, FILTER_SANITIZE_STRING);
if ($sanitized_data) {
    // Store the validated JSON data in the database
    $json_data = json_encode($sanitized_data);
} else {
    // Handle validation errors
    echo "Invalid JSON data";
}
