Asort

(PHP3, PHP4)

Asort---A relationship that arranges arrays and maintains index values

Grammar: void&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP;" Asort (array array);

Description:

This function rearranges the elements of an array by a-Z and retains the corresponding relationship between the original index value and the element, which is used primarily to rearrange the elements of the array.

Example:

<?php

$fruits = Array ("D" => "Lemon", "a" => "Orange", "B" => "banana", "C" => "Apple");

Asort ($fruits);

for (Reset ($fruits); $key = key ($fruits); next ($fruits)) {

echo "fruits[$key] =". $fruits [$key]. " \ n ";

}

?>

The results of this example are:

FRUITS[C] = Apple

FRUITS[B] = Banana

FRUITS[D] = Lemon

Fruits[a] = Orange

This shows that the array fruits has been rearranged, and that the relationship between the index values and elements remains unchanged.
