What are some potential pitfalls when working with timezones in PHP, especially when trying to display user-friendly descriptions alongside ISO timezones?

When working with timezones in PHP and trying to display user-friendly descriptions alongside ISO timezones, one potential pitfall is accurately mapping ISO timezones to user-friendly descriptions. To solve this, you can utilize the DateTimeZone class in PHP to get a list of supported timezones and then create a mapping array to pair ISO timezones with user-friendly descriptions. 

// Get list of supported timezones
$timezones = DateTimeZone::listIdentifiers();

// Create mapping array for ISO timezones and user-friendly descriptions
$timezoneDescriptions = [
    'UTC' => 'Coordinated Universal Time',
    'America/New_York' => 'Eastern Time',
    'America/Los_Angeles' => 'Pacific Time',
    // Add more timezone mappings as needed
];

// Display user-friendly timezone description
$selectedTimezone = 'America/New_York'; // Example ISO timezone
echo $timezoneDescriptions[$selectedTimezone];
