Array Sort in PHP |
We can sort array elements in different ways. We will try to learn different types of sorting here. Let us start with a simple sort command.
Here is the code for a simple sort.
The code is given here and the output is below that.
<?
$input = array ("Apple", "Orange", "Banana", "Mango", "Pinaple","Strawberry");
while (list ($key, $val) = each ($input)) {
echo "$key -> $val <br>";
}
sort($input);
echo "<br>-----After sort---------<br>";
while (list ($key, $val) = each ($input)) {
echo "$key -> $val <br>";
}
?>
Loking for the output? Here it is
0 -> Apple
1 -> Orange
2 -> Banana
3 -> Mango
4 -> Pinaple
5 -> Strawberry
-----After sort---------
0 -> Apple
1 -> Banana
2 -> Mango
3 -> Orange
4 -> Pinaple
5 -> Strawberry
