What are some common pitfalls to avoid when sorting data in PHP?

One common pitfall to avoid when sorting data in PHP is not specifying the correct sorting method. If you do not specify a sorting method, PHP will default to sorting data as strings, which may not give you the desired results when sorting numbers or dates. To avoid this pitfall, always specify the correct sorting method when using PHP's sorting functions. 

// Incorrect way of sorting data without specifying sorting method
$data = [10, 5, 3, 8];
sort($data); // This will sort the data as strings, not numbers

// Correct way of sorting data by specifying sorting method
$data = [10, 5, 3, 8];
sort($data, SORT_NUMERIC); // This will sort the data as numbers
