PHP中使用了mcrypt_decrypt函数处理Json串后导致Json_decode返回null问题
昨天在对生成的json文件进行decode操作时 突然发现返回的是NUll，（json文件里面的json串是加密后的），经过反复测试 ，发现只要json中包含中文字符，并进行解密操作后，就导致decode操作返回NULL，如果没有汉字是正常的decode.
刚开始以为是编码导致，反复测试后，还是有问题，最后找到解密操作里面，发现了mcrypt_decrypt 函数，查手册发现 这个函数有可能在返回的字符后面 带上隐藏字符 \0 ,会不会是这个造成的呢？ 于是使用str_replace("\0","",$json); 结果就出来了，我擦，浪费了半天时间。
