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[$i])>=6 && strlen($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。
