Grammar
Sort (array,sorttype) parameter description
Array required. The input array.
SortType is optional. Specifies how the values of the array are arranged. Possible values:
Sort_regular-Default. Processed in their original type (without changing the type).
Sort_numeric-Handle the value as a number
Sort_string-handles the value as a string
Sort_locale_string-handles the value as a string, based on local settings *.
*: This value is new for PHP 4.4.0 and 5.0.2. Prior to PHP 6, the system's locale was used, which can be changed using setlocale (). From PHP 6, you must use the I18n_loc_set_default () function.
Example
<?php $my _array = Array ("A" = "Dog", "b" = "Cat", "c" = "Horse"); Sort ($my _array); Print_r ($my _array);?>
Output:
Array ([0] = Cat [1] = Dog [2] = = Horse)
