分享下php生成随机数的三种方法，生成1-10之间的不重复随机数，php生成不重复随机数的例子，需要的朋友参考下。

如何用php生成1-10之间的不重复随机数？

例1，使用shuffle函数生成随机数。

<" ";
}
"htmlcode">



<" ",$arr);
"htmlcode">



<" ";
 }
echo "<br/>";
$arr=array_values($return);// 获得数组的值 
foreach($arr as $key)
echo $key." ";
"htmlcode">



<"218","218","66","66","218","218","60","60","202","204","66","66","66","59","61","60","222","221","66","59","60","60","66","218","218","62","63","64","66","66","122","211"); 
$randarr= mt_rand(0,count($arr_1)-1); 
$ip1id = $arr_1[$randarr]; 
echo $ip1id; 
echo "."; 
echo $ip2id; 
echo "."; 
echo $ip3id; 
echo "."; 
echo $ip4id; 
"htmlcode">



<"http://66.249.89.99","http://66.249.89.104","http://74.125.71.105"); 
$randarr= mt_rand(0,count($arr_1)-1); 
$gip= $arr_1[$randarr]; 
echo $gip."$randarr"; 
?>
