What are the common pitfalls when sorting arrays in PHP and how can they be avoided?

Common pitfalls when sorting arrays in PHP include not specifying the sorting method, not using the correct sorting function for the data type, and not handling cases where the array contains mixed data types. To avoid these pitfalls, always specify the sorting method (e.g., SORT_NUMERIC, SORT_STRING, SORT_REGULAR) when using sorting functions like sort(), asort(), ksort(), etc. Additionally, make sure to use the appropriate sorting function based on the data type of the array elements to ensure correct sorting results.

// Example of sorting an array of integers using the correct sorting function
$numbers = [5, 2, 8, 1, 3];
sort($numbers, SORT_NUMERIC);
print_r($numbers);
