PHP base64+gzinflate压缩编码和解码代码

base64+gzinflate压缩编码（加密）过的文件通常是以 <? eval(gzinflate(base64_decode( 为头的一个php文件。文中给出了编码和解码的代码。CODE:<?phpfunction 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$pos = strpos($contents,'/*Protected by 草名http://www.crazyi.cnCryptation*/');if(false === $pos || $pos>100){ // 去除PHP文件注释和空白，减少文件大小$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$encode = '<?php'.' /*Protected by 草名http://www.crazyi.cnCryptation*/n eval(gzinflate(base64_decode('.$encode.')));n /*Reverse engineering is illegal and strictly prohibited- (C)草名 Cryptation 2008*/ n?>';return file_put_contents($filename,$encode);}}return false;}//调用函数$filename='g:我的文档桌面test.php';encode_file_contents($filename);?><?phpfunction 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$pos = strpos($contents,'/*Protected by 草名http://www.crazyi.cnCryptation*/');if(false === $pos || $pos>100){ // 去除PHP文件注释和空白，减少文件大小$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$encode = '<?php'.' /*Protected by 草名http://www.crazyi.cnCryptation*/n eval(gzinflate(base64_decode('.$encode.')));n /*Reverse engineering is illegal and strictly prohibited- (C)草名 Cryptation 2008*/ n?>';return file_put_contents($filename,$encode);}}return false;}//调用函数$filename='g:我的文档桌面test.php';encode_file_contents($filename);?>

压缩解码（解密）代码：[复制此代码]CODE:<?php$Code = '这里填写要解密的编码'; // base64编码$File = 'test.php';//解码后保存的文件$Temp = base64_decode($Code);$temp = gzinflate($Temp);$FP = fopen($File,'w');fwrite($FP,$temp);fclose($FP);echo '解密成功！';?>
