解密ZEND加密后的PHP
先下載http://pecl.php.net/get/vl...

執(zhí)行
#tar -xzf vld-0.8.0.tgz //解壓
#mv vld-0.8.0 vld //重命名
#cd -R vld ../php-4.3.8/ext //拷貝vld目錄到php的解壓目錄下的ext中
#cd php-4.3.8
#rm configure //刪除configure,因為下面的buildconf會重新生成新的configure
#./buildconf //如果出現(xiàn)錯誤,就按提示加上相應的參數(shù).
#./configure --with-mysql --with-apxs2=/usr/www/bin/apxs --enable-vld 重新檢查php
#make 編譯
#make install 安裝

服務(wù)器必須先安裝ZendOptimizer
運行Zend后的文件,查看源代碼就可以看到了.

方法二：
只要你有ｌｉｎｕｘ主機，再裝一個程序，就能瀏覽源碼了．
