array_sort()

The sort() function sorts an indexed array in ascending order.

sort(array,sortingtype);

In above syntax, ""array" specifies the array to sort and "sortingtype" specifies how to compare the array elements/items by using values are as follows:

• 0 = SORT_REGULAR - Default. Compare items normally (don't change types)
• 1 = SORT_NUMERIC - Compare items numerically
• 2 = SORT_STRING - Compare items as strings
• 3 = SORT_LOCALE_STRING - Compare items as strings, based on current locale
• 4 = SORT_NATURAL - Compare items as strings using natural ordering
• 5 = SORT_FLAG_CASE -

Example:

<?php
$fruits=array("Apple","Mango","Banana");
sort($fruits);

$flength=count($fruits);
for($x=0;$x<$flength;$x++)
   {
   echo $fruits[$x];
   echo "<br>";

Output:

Apple
Banana
