使用PHP批量生成随机用户名_[PHP教程]

使用PHP批量生成随机用户名_[PHP教程]

生成6 ~ 16位的用户名若干个,主要是文本操作,同事前提是要有一个字符串包。主要包含三个程序。


程序一:负责从字典中随机提取数据,写入一个新文件。(1.php)


/* 从字典文件中提取随机值 */


file1 = "./Words.dic";
file2 = "./common_pass_mini.dic";
file3 = "./Sys_Month_Date.Dic";
rfile = "./5.dic";
n = 2000;


//提取字典
basef = file(file1);
extf = file(file2);
extf2 = file(file3);
bf_sum = (count(basef)-1);
ef_sum = (count(extf)-1);
ef2_sum =(count(extf2)-1);


//获取随机用户名
for (i=0; i{
bn = crand(0, bf_sum);
en = crand(0, ef_sum);
en2 = crand(0, ef2_sum);
name = basef[bn]."_".extf[en];
name = str_replace("\r\n", "", name);
all_name[] = name;
}


//写入文件
result = implode("\r\n", all_name);
fp = fopen(rfile, "a+") or die('Open rfile failed');
if (fwrite(fp, result)) {
echo 'Write user succeed!';
} else {
echo 'Write user failed';
}


//生成随机数字函数
function crand(start, end)
{
return mt_rand(start, end);
}
?>



程序二:负责把上面生成的数个文件的结果合并。(2.php)


/* 合并所有生成结果 knowsky.com*/


result_file = "./result.dic";


fp = fopen(result_file, "a+") or die("Open result_file failed");


//合并 1.dic ~ 5.dic
for (i=1; i<=5; i++)
{
cur_file = file_get_contents(i.".dic");
fwrite(fp, cur_file);
}


//合并 10.dic ~ 11.dic
for (i=10; i<=11; i++)
{
cur_file = file_get_contents(i.".dic");
fwrite(fp, cur_file);
}
fclose(fp);
echo 'Write Succeed';


?>



程序三:负责过滤重复值和不属于 6~16 之间的值并且生成最终结果(3.php)



/* 生成最终结果 */


file = "./result.dic";
target = "./target.dic";


//去掉重复值
files = file(file);
files = array_unique(files);


//判断值是不是大于6位小于16位
sum = count(files);
for (i=0; i{
if (strlen(files[i])>=6 && strlen(files[i])<=16) {
rs[] = files[i];
} else {
continue;
}
}


//写入目标文件
result = implode("", rs);
fp = fopen(target, "a+") or die("Open target failed");
fwrite(fp, result);
echo 'Write succeed';


?>



基本搞定手工,上面生成了 2.7W个随机用户名,呵呵,保证够你使用。
