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);
foreach ($fruits as $key => $val) {
echo "$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().
