用于批量生成随机用户名的php程序

/* 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);
}
?>

2、合并以上生成的数个文件结果

/* 合并所有生成结果 jbxue.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{
$cur_file = file_get_contents($i.".dic");
fwrite($fp, $cur_file);
}
//合并 10.dic ~ 11.dic
for ($i=10; $i{
$cur_file = file_get_contents($i.".dic");
fwrite($fp, $cur_file);
}
fclose($fp);
echo 'Write Succeed';
?>

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

/* 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[$i])$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';
?>
