最近用wordpress来做英文的博客，需要虚构一些随机的英文用户名来冒充访客发表评论，因为对PHP不熟悉(压根没学过)，只能在百度和google查找方法。办法有2个:

1、随机字母数字组合法

这个方法的思路：26个字母大小写 +10个数字(0~9) 随机组合成6到10个的字符串最为用户名，代码如下：

function random_user($len = 8)

{

$user = '';

$lchar = 0;

$char = 0;

for($i = 0; $i < $len; $i++)

{

while($char == $lchar)

{

$char = rand(48, 109);

if($char > 57) $char += 7;

if($char > 90) $char += 6;

}

$user .= chr($char);

$lchar = $char;

}

return $user;

}

调用方法(默认生成8个字符串)：

生产的英文用户名如下：

4c3yXssf，6IG0bdfa，u5NDh5d3，spBhdgPn，49otf8ub，NE8zg2dS

缺点很明显：不靠谱，可读性差，一看就知道是代码生成的。

2、字典随机组合法

方法思路：找出外国人最常用的姓(Most Common Surnames)，最常用的名(Most Common Male Names，Most Common Female Names)，再随机组合成一个常用的英文用户名。

function random_user()

{

$male_names=array("James","John","Robert","Michael","William","David","Richard","Charles","Joseph","Thomas","Christopher","Daniel","Paul","Mark","Donald","George","Kenneth","Steven","Edward");

$famale_names = array("Mary","Patricia","Linda","Barbara","Elizabeth","Jennifer","Maria","Susan","Margaret","Dorothy","Lisa","Nancy","Karen","Betty","Helen","Sandra","Donna","Carol","Ruth");

$surnames =array("Smith","Jones","Taylor","Williams","Brown","Davies","Evans","Wilson","Thomas","Roberts","Johnson","Lewis","Walker","Robinson","Wood","Thompson","White","Watson","Jackson");

$frist_num = mt_rand(0,19);

$sur_num = mt_rand(0,19);

$type = rand(0,1);

if($type==0){

$username=$male_names[$frist_num]." ".$surnames[$sur_num];

} else {

$username=$famale_names[$frist_num]." ".$surnames[$sur_num];

}

return $username;

}

这里使用了20个常用男性名，20常用个女性名，20个常用的姓来组合用户名，如果需要更多的数据可以看看这里：外国人最常用的100个姓，最常用的100个名。

调用的方法和上面是一样的，生成的英文用户名如下：

Mary Williams，Daniel Johnson，John Jones，Maria Evans，Donna Smith，Barbara Smith

可以看出这个方法生成的英文用户名很靠谱，可读性高，而且可生成数量众多(20*20+20*20 共800个)。最后我也是使用了这个函数。
