Description
bool
arsort ( array &array [, int sort_flags] )
This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the
actual element order is significant.
Returns TRUE on success or FALSE on failure.
Example 1. arsort() example
<?php
$fruits = array("d" => "lemon", "a"
=> "orange", "b" => "banana", "c" => "apple");
arsort($fruits);
reset($fruits);
while (list($key, $val) = each($fruits)) {
echo "$key = $val\n";
}
?> |
The above example will output:
a = orange
d = lemon
b = banana
c = apple
|
|
The fruits have been sorted in reverse alphabetical order, and the index associated with each element has been maintained.
You may modify the behavior of the sort using the optional parameter sort_flags, for details see sort().
