使用PHP批量生成隨機(jī)用戶名
程序一：負(fù)責(zé)從字典中隨機(jī)提取數(shù)據(jù)，寫入一個(gè)新文件。（1.php）
復(fù)制代碼 代碼如下:
<?php
/* 從字典文件中提取隨機(jī)值 */
$file1 = "./Words.dic";
$file2 = "./common_pass_mini.dic";
$file3 = "./Sys_Month_Date.Dic";
$rfile = "./5.dic";
$n = 2000;
/pic/p>
$basef = file($file1);
$extf = file($file2);
$extf2 = file($file3);
$bf_sum = (count($basef)-1);
$ef_sum = (count($extf)-1);
$ef2_sum =(count($extf2)-1);
/pic/p>
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;
}
/pic/p>
$result = implode("/r/n", $all_name);
$fp = fopen($rfile, "a+") or die('Open $rfile failed');
if (fwrite($fp, $result)) {
echo 'Write user succeed!';
} else {
echo 'Write user failed';
}
/pic/p>
function crand($start, $end)
{
return mt_rand($start, $end);
}
?>
程序二：負(fù)責(zé)把上面生成的數(shù)個(gè)文件的結(jié)果合并。（2.php）
復(fù)制代碼 代碼如下:
<?php
/* 合并所有生成結(jié)果 jb51.net*/
$result_file = "./result.dic";
$fp = fopen($result_file, "a+") or die("Open $result_file failed");
/pic/p>
for ($i=1; $i<=5; $i++)
{
$cur_file = file_get_contents($i.".dic");
fwrite($fp, $cur_file);
}
/pic/p>
for ($i=10; $i<=11; $i++)
{
$cur_file = file_get_contents($i.".dic");
fwrite($fp, $cur_file);
}
fclose($fp);
echo 'Write Succeed';
?>
程序三：負(fù)責(zé)過濾重復(fù)值和不屬于 6~16 之間的值并且生成最終結(jié)果（3.php）
復(fù)制代碼 代碼如下:
<?php
/* 生成最終結(jié)果 */
$file = "./result.dic";
$target = "./target.dic";
/pic/p>
$files = file($file);
$files = array_unique($files);
/pic/p>
$sum = count($files);
for ($i=0; $i<$sum; $i++)
{
if (strlen($files[$i])>=6 && strlen($files[$i])<=16) {
$rs[] = $files[$i];
} else {
continue;
}
}
/pic/p>
$result = implode("", $rs);
$fp = fopen($target, "a+") or die("Open $target failed");
fwrite($fp, $result);
echo 'Write succeed';
?>
