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.

How to use php sort to implement a sort

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>";
   }
?>
