How can debugging techniques be used to troubleshoot issues with array sorting in PHP?

When troubleshooting array sorting issues in PHP, you can use debugging techniques such as printing the array before and after sorting to identify any discrepancies. Additionally, you can check if the sorting function is correctly implemented and if the array elements are of the correct data type for sorting. By carefully examining these factors, you can pinpoint the root cause of the sorting issue and implement the necessary fixes.

// Example code snippet for debugging array sorting in PHP
$array = [3, 1, 5, 2, 4];
echo "Before sorting: ";
print_r($array);

sort($array);

echo "After sorting: ";
print_r($array);
