sort

Description

bool sort ( array &array [, int sort_flags] )

This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.

Returns TRUE on success or FALSE on failure.

Example 1. sort() example <?php $fruits = array("lemon", "orange", "banana", "apple"); sort($fruits); foreach ($fruits as $key => $val) {     echo "fruits[" . $key . "] = " . $val . "\n"; } ?> The above example will output: fruits[0] = apple fruits[1] = banana fruits[2] = lemon fruits[3] = orange

The fruits have been sorted in alphabetical order.

The optional second parameter sort_flags may be used to modify the sorting behavior using these values:

Sorting type flags:

• SORT_REGULAR - compare items normally (don't change types)

• SORT_NUMERIC - compare items numerically

• SORT_STRING - compare items as strings

• SORT_LOCALE_STRING - compare items as strings, based on the current locale. Added in PHP 4.4.0 and 5.0.2. Before PHP 6, it uses the system locale, which can be changed using setlocale(). Since PHP 6, you must use the i18n_loc_set_default() function.
