What potential pitfalls should be considered when using sort() and natsort() functions in PHP for sorting arrays?

When using the sort() function in PHP to sort arrays, be aware that it sorts the array in ascending order based on values, which may not be the desired outcome if you need a natural sorting order. In such cases, using the natsort() function is more appropriate as it sorts the array in a natural order. However, be cautious when using natsort() as it can sometimes lead to unexpected results if the array contains mixed data types or special characters.

// Using natsort() to sort an array in natural order
$array = ['img1', 'img10', 'img2', 'img20'];
natsort($array);
print_r($array);
