此函数没有参数。
没有返回值。
Example #1 ArrayObject::ksort() example
<?php
$fruits = array( "d" => "lemon" , "a" => "orange" , "b" => "banana" , "c" => "apple" );
$fruitArrayObject = new ArrayObject ( $fruits );
$fruitArrayObject -> ksort ();
foreach ( $fruitArrayObject as $key => $val ) {
echo " $key = $val \n" ;
}
?>
以上例程会输出:
