What potential pitfalls should be considered when using string functions to manipulate date formats in PHP?

When using string functions to manipulate date formats in PHP, potential pitfalls to consider include incorrect conversions due to different date formats, errors when handling time zones, and the risk of introducing bugs if the string functions are not used correctly. To avoid these pitfalls, it is recommended to use PHP's built-in DateTime class for date manipulation, as it provides more robust functionality and better handling of date formats and time zones. 

// Using DateTime class to manipulate date formats
$dateString = "2022-01-15";
$date = DateTime::createFromFormat('Y-m-d', $dateString);
$newDateFormat = $date->format('d/m/Y');

echo $newDateFormat; // Output: 15/01/2022
