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.dicfor (i=1; i<=5; i++){ cur_file = file_get_contents(i.".dic"); fwrite(fp, cur_file);}
//合并 10.dic ~ 11.dicfor (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。
