What are potential pitfalls to be aware of when converting date formats in PHP?

When converting date formats in PHP, one potential pitfall to be aware of is mismatched formats between the input date and the desired output format, which can result in incorrect conversions. To avoid this issue, always ensure that the input date format matches the format specified in the date() function for the desired output.

$input_date = "2022-01-15";
$output_format = "d/m/Y";
$converted_date = date_create_from_format('Y-m-d', $input_date)->format($output_format);
echo $converted_date;
