sort
(PHP 3, PHP 4 , PHP 5)
sort -- Sort an array
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.
Замечание: This function assigns new keys for the elements in array. It will remove any existing keys you may have assigned, rather than just reordering the keys.
Возвращает TRUE в случае успешного завершения, FALSE в случае возникновения ошибки.
Пример 1. sort() example
<?php
$fruits = array("lemon", "orange", "banana", "apple");
sort($fruits);
reset($fruits);
while (list($key, $val) = each($fruits)) {
echo "fruits[" . $key . "] = " . $val . "\n";
}
?> |
This example would display:
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
-
SORT_NUMERIC - compare items numerically
-
SORT_STRING - compare items as strings
Замечание: The second parameter was added in PHP 4.
