第一种php加密方法：
<?php
function encode_file_contents($filename) {
$type=strtolower(substr(strrchr($filename,'.'),1));
if ('php' == $type && is_file($filename) && is_writable($filename)) { // 如果是PHP文件 并且可写 则进行压缩编码
   $contents = file_get_contents($filename); // 判断文件是否已经被编码处理
   $contents = php_strip_whitespace($filename);

   // 去除PHP头部和尾部标识
   $headerPos = strpos($contents,'<?php');
   $footerPos = strrpos($contents,'?>');
   $contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);
   $encode = base64_encode(gzdeflate($contents)); // 开始编码
   $encode = '<?php'."\n eval(gzinflate(base64_decode("."'".$encode."'".")));\n\n?>";

   return file_put_contents($filename, $encode);
}
return false;
}

//调用函数
$filename = 'dam.php';
encode_file_contents($filename);
echo "OK,加密完成！"
?>第二种php加密方法：
<?php

function RandAbc($length = "") { // 返回随机字符串
$str = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
return str_shuffle($str);
}

$filename = 'index.php'; //要加密的文件
$T_k1 = RandAbc(); //随机密匙1
$T_k2 = RandAbc(); //随机密匙2
$vstr = file_get_contents($filename);
$v1 = base64_encode($vstr);
$c = strtr($v1, $T_k1, $T_k2); //根据密匙替换对应字符。
$c = $T_k1.$T_k2.$c;
$q1 = "O00O0O";
$q2 = "O0O000";
$q3 = "O0OO00";
$q4 = "OO0O00";
$q5 = "OO0000";
$q6 = "O00OO0";
$s = '$'.$q6.'=urldecode("%6E1%7A%62%2F%6D%615%5C%76%740%6928%2D%70%78%75%71%79%2A6%6C%72%6B%64%679%5F%65%68%63%73%77%6F4%2B%6637%6A");$'.$q1.'=$'.$q6.'{3}.$'.$q6.'{6}.$'.$q6.'{33}.$'.$q6.'{30};$'.$q3.'=$'.$q6.'{33}.$'.$q6.'{10}.$'.$q6.'{24}.$'.$q6.'{10}.$'.$q6.'{24};$'.$q4.'=$'.$q3.'{0}.$'.$q6.'{18}.$'.$q6.'{3}.$'.$q3.'{0}.$'.$q3.'{1}.$'.$q6.'{24};$'.$q5.'=$'.$q6.'{7}.$'.$q6.'{13};$'.$q1.'.=$'.$q6.'{22}.$'.$q6.'{36}.$'.$q6.'{29}.$'.$q6.'{26}.$'.$q6.'{30}.$'.$q6.'{32}.$'.$q6.'{35}.$'.$q6.'{26}.$'.$q6.'{30};eval($'.$q1.'("'.base64_encode('$'.$q2.'="'.$c.'";eval(\'?>\'.$'.$q1.'($'.$q3.'($'.$q4.'($'.$q2.',$'.$q5.'*2),$'.$q4.'($'.$q2.',$'.$q5.',$'.$q5.'),$'.$q4.'($'.$q2.',0,$'.$q5.'))));').'"));';

$s = '<?php '."\n".$s."\n".' ?>';
//echo $s;
// 生成 加密后的PHP文件
$fpp1 = fopen('temp_'.$filename, 'w');
fwrite($fpp1, $s) or die('写文件错误');

使用方法参考如下：
// 加密过程
view sourceprint?
$text_file = S_ROOT . './456.php';
$str = @file_get_contents($text_file);

require_once S_ROOT . "./text_auth.php";
$text_auth = new text_auth(64);

$str = $text_auth->encrypt($str, "qianyunlai.com");

$filename = S_ROOT . './789.php'; // 加密后的文本为二进制，普通的文本编辑器无法正常查看
file_put_contents($filename, $str);
// 解密过程
view sourceprint
?01 $text_file = S_ROOT . './789.php';
$str = @file_get_contents($text_file);

require_once S_ROOT . "./text_auth.php";
$text_auth = new text_auth(64);

$str = $text_auth->decrypt($str, "qianyunlai.com");

$filename = S_ROOT . './456.php';
file_put_contents($filename, $str);
