PHP批量生成随机用户名,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) - <?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<n; 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) - <?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) - <?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<sum; i++)
- {
- if (strlen(files)>=6 && strlen(files)<=16) {
- rs[] = files;
- } 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';
-
- ?>
搞定,上面生成了 2.7W个随机用户名。
