求PHP数组最大值,最小值的代码

代码如下:

<?php 
$fruits = array("155::vbscript:://www.gxlcms.com/list/list_114_1.htm", "1::javascript:://www.gxlcms.com/list/list_3_1.htm", "2::正则表达式:://www.gxlcms.com/list/list_6_1.htm", "3::服务器常用软件::http://s.jb51.net"); 
print_r($fruits); 
rsort($fruits,SORT_NUMERIC); 
print_r($fruits); 
?> 
 
显示结果： 

Array 
( 
[0] => 155::vbscript:://www.gxlcms.com/list/list_114_1.htm 
[1] => 1::javascript:://www.gxlcms.com/list/list_3_1.htm 
[2] => 2::正则表达式:://www.gxlcms.com/list/list_6_1.htm 
[3] => 3::服务器常用软件::http://s.jb51.net 
)
