用于批量生成随机用户名的php程序

3. /* 从字典文件中提取随机值 */

4. $file1 = "./Words.dic";
5. $file2 = "./common_pass_mini.dic";
6. $file3 = "./Sys_Month_Date.Dic";
7. $rfile = "./5.dic";
8. $n = 2000;

9. //提取字典

10. $basef = file($file1);
11. $extf = file($file2);
12. $extf2 = file($file3);
13. $bf_sum = (count($basef)-1);
14. $ef_sum = (count($extf)-1);
15. $ef2_sum =(count($extf2)-1);

16. //获取随机用户名

17. for ($i=0; $i<$n; $i++)
18. {
19. $bn = crand(0, $bf_sum);
20. $en = crand(0, $ef_sum);
21. $en2 = crand(0, $ef2_sum);
22. $name = $basef[$bn]."_".$extf[$en];
23. $name = str_replace("/r/n", "", $name);
24. $all_name[] = $name;
25. }

26. //写入文件

27. $result = implode("/r/n", $all_name);
28. $fp = fopen($rfile, "a+") or die('Open $rfile failed');
29. if (fwrite($fp, $result)) {
30. echo 'Write user succeed!';
31. } else {
32. echo 'Write user failed';
33. }

34. //生成随机数字函数

35. function crand($start, $end)
36. {
37. return mt_rand($start, $end);
38. }
39. ?>

2、合并以上生成的数个文件结果

3. /* 合并所有生成结果 jbxue.com*/

4. $result_file = "./result.dic";

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

6. //合并 1.dic ~ 5.dic

7. for ($i=1; $i<=5; $i++)
8. {
9. $cur_file = file_get_contents($i.".dic");
10. fwrite($fp, $cur_file);
11. }

12. //合并 10.dic ~ 11.dic

13. for ($i=10; $i<=11; $i++)
14. {
15. $cur_file = file_get_contents($i.".dic");
16. fwrite($fp, $cur_file);
17. }
18. fclose($fp);
19. echo 'Write Succeed';
20. ?>

3、过滤重复值和不属于 6~16 之间的值，并生成最终可用数据

3. /* 生成最终结果 */

4. $file = "./result.dic";

5. $target = "./target.dic";

6. //去掉重复值

7. $files = file($file);
8. $files = array_unique($files);

9. //判断值是不是大于6位小于16位

10. $sum = count($files);
11. for ($i=0; $i<$sum; $i++)
12. {
13. if (strlen($files[$i])>=6 && strlen($files[$i])<=16) {
14. $rs[] = $files[$i];
15. } else {
16. continue;
17. }
18. }

19. //写入目标文件

20. $result = implode("", $rs);
21. $fp = fopen($target, "a+") or die("Open $target failed");
22. fwrite($fp, $result);
23. echo 'Write succeed';
24. ?>
