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>
