在PHP中重新排序数组的最佳方法是什么[重复]

Here is an array:

$array = (0 => "pear", 1 => "apple", 2 => "orange", 3 => "kiwi");

What is the best way to reorder the array to become:

$array = (0 => "pear", 1 => "kiwi", 2 => "orange", 3 => "apple");

Edit:

Please note I am not looking for an alphabetical sort. I am looking to switch the order of two items within an array. My initial thought was to pop out the key=>value pair that I want to change, then reinsert it. But I want to know if there is a better way.

Use this code to switch 2 values of your array:

$tmp = $array[1];
$array[1] = $array[3];
$array[3] = $tmp;
unset($tmp); // you may delete the variable if you no longer need it

Use asort($array) to sort an array.

I think you can use asort to sort your array alphabetically

General example

$fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple");
asort($fruits);
foreach ($fruits as $key => $val) {
    echo "$key = $val
";
}

This will output

c = apple
b = banana
d = lemon
a = orange

I would simply use:

$list = array('apple', 'pear', 'kiwi');
sort($list);
var_dump($list);

This is imho the best for not associative arrays.
