In PHP, sort can be used to sort a numerical array in ascending order. The syntax is "sort (array to be sorted, specifying how to sort the elements of the array)"; if the sorting is successful, the returned result is true , if it fails, it returns false. The element parameter that specifies how to sort the array defaults to "1", which means that each item is arranged in a regular order.

sort() function sorts a numeric array in ascending order.
Tip: Please use the rsort() function to sort the numeric array in descending order.
Syntax
sort(array,sortingtype);
array Required. Specifies the array to be sorted.
sortingtype Optional. Specifies how the elements/items of an array are arranged. Possible values:
#0 = SORT_REGULAR - Default. Put each item in regular order (Standard ASCII, don't change the type).
1 = SORT_NUMERIC - treat each item as a number.
2 = SORT_STRING - Treat each item as a string.
3 = SORT_LOCALE_STRING - Treat each item as a string, based on the current locale (can be changed via setlocale()).
4 = SORT_NATURAL - Treat each item as a string, using natural sorting like natsort().
5 = SORT_FLAG_CASE - Can be combined (bitwise OR) with SORT_STRING or SORT_NATURAL to sort strings, case-insensitively.
Return value: TRUE if successful, FALSE if failed.
The example is as follows:
<?php $numbers=array(4,6,2,22,11); sort($numbers); $arrlength=count($numbers); for($x=0;$x<$arrlength;$x++) { echo $numbers[$x]; echo "<br>"; } ?>
Output result:
