# PHP Function array_flip()

## Syntax

array array_flip ( array $input );

array_flip() returns an array in flip order, i.e. keys from input become values and values from input become keys.

If a value has several occurrences, the latest key will be used as its values, and all others will be lost.

## Paramters

## Return Values

## Example

Try out following example:

    <?php
    $array = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);

    print_r(array_flip($array));
    ?>

This will produce following result:

    Array ( [1] => a [2] => b [3] => c [4] => d [5] => e)
