What potential issues can arise when using the isLocked() function in the core.php file?

The potential issue that can arise when using the isLocked() function in the core.php file is that it may not properly check for the lock status of a resource, leading to incorrect behavior or unauthorized access. To solve this issue, you can modify the isLocked() function to use a more secure and reliable method of checking the lock status, such as using a database query or a file lock. 

// Modified isLocked() function to use a database query to check lock status
function isLocked($resource_id) {
    // Connect to the database
    $conn = new mysqli('localhost', 'username', 'password', 'database');

    // Check if the resource is locked
    $query = "SELECT is_locked FROM resources WHERE id = ?";
    $stmt = $conn->prepare($query);
    $stmt->bind_param('i', $resource_id);
    $stmt->execute();
    $stmt->bind_result($is_locked);
    $stmt->fetch();

    // Close the database connection
    $stmt->close();
    $conn->close();

    return $is_locked;
}
