How can PHP beginners handle different date formats and ensure accurate date conversions?

Handling different date formats in PHP can be challenging for beginners. To ensure accurate date conversions, beginners can use the `DateTime` class in PHP, which allows for easy manipulation and formatting of dates. By using the `createFromFormat()` method, beginners can specify the input date format and convert it to a standard format for processing.

// Example of converting date from different formats to a standard format
$dateString = '2022-05-15'; // Input date in YYYY-MM-DD format
$date = DateTime::createFromFormat('Y-m-d', $dateString);
$standardDateFormat = $date->format('Y-m-d'); // Output date in YYYY-MM-DD format

echo $standardDateFormat; // Output: 2022-05-15
