分享2种PHP的源码加密方式,此加密方法支持任意PHP版。
注意,加密后的PHP代码无需第三方工具解密,像往常一样,直接运行即可。
<?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!" ?>

其实,PHP加密源码方式有很多,譬如,免费的微盾PHP加密,还有 www.phpjm.net 搞的在线加密,只是phpjm更复杂点而已。

另外,分享一个 PHP类,它能对 文本的内容进行 二进制加密 与 解密,代码如下:
