php通过asort()给关联数组按照值排序的方法,asort数组

本文实例讲述了php通过asort()给关联数组按照值排序的方法。分享给大家供大家参考。具体分析如下:

php通过asort()给关联数组按照值排序,和sort的区别是,sort为数组中的单元赋予新的键名。原有的键名将被删除。

$nums = array("one"=>5,"two"=>2,"three"=>1);
asort( $nums );
foreach ( $nums as $key => $val ) {
 print "$key = $val<br />";
}

希望本文所述对大家的php程序设计有所帮助。
