What are the potential pitfalls of sorting data within a while loop in PHP?

Sorting data within a while loop in PHP can be inefficient and resource-intensive, especially for large datasets. It can also lead to unexpected results as the data may not be sorted correctly during each iteration of the loop. To address this issue, it is recommended to fetch and sort the data before entering the while loop. 

// Fetch and sort data before entering the while loop
$data = [4, 2, 1, 3];
sort($data);

// Iterate over the sorted data
foreach($data as $value) {
    echo $value . " ";
}
