The variable $fruits isn't declared. $frutas must be used.
The variables $key and $val are wrong too.


<?php
$frutas = array("d" => "limao", "a" => "laranja", "b" => "banana", "c" => 
"melancia");
arsort($frutas);
foreach ($fruits as $key => $val) {
    echo "$chave = $valor\n";
}
?>

Test script:
---------------
<?php
$frutas = array("d" => "limao", "a" => "laranja", "b" => "banana", "c" => 
"melancia");
arsort($frutas);
foreach ($fruits as $key => $val) {
    echo "$chave = $valor\n";
}
?>

Expected result:
----------------
<?php
$frutas = array("d" => "limao", "a" => "laranja", "b" => "banana", "c" => 
"melancia");
arsort($frutas);
foreach ($frutas as $chave => $valor) {
    echo "$chave = $valor\n";
}
?>

Actual result:
--------------
""
