<para>
Sorts an array by key in reverse order, maintaining key to data correlations. This
is useful mainly for associative arrays.
<example>
<title><function>krsort</function> example</title>
<programlisting>
$fruits = array("d"=>"lemon","a"=>"orange","b"=>"banana","c"=>"apple");
krsort($fruits);
for(reset($fruits); $key = key($fruits); next($fruits)) {
echo "fruits[$key] = ".$fruits[$key]."\n";
}
</programlisting></example>
This example would display:
<computeroutput>
fruits[d] = lemon
fruits[c] = apple
fruits[b] = banana
fruits[a] = orange
</computeroutput>
