php one use write dictionary batch extract data document new file generate use program random

程序一:负责从字典中随机提取数据,写入一个新文件。(1.php)

复制代码 代码如下:


/* 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)

复制代码 代码如下:


/* 合并所有生成结果 jb51.net*/

$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';

?>


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)

复制代码 代码如下:


/* 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';
?>


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。
