ecshop适应在PHP7的修改方法解决报错的实现

《PHP实例：ecshop适应在PHP7的修改方法解决报错的实现》要点：
本文介绍了PHP实例：ecshop适应在PHP7的修改方法解决报错的实现，希望对您有用。如果有疑问，可以联系我们。

ecshop这个系统,到目前也没见怎么推出新版本,如果是新项目,不太建议使用它.不过,因为我一直以来都在使用中,所以不得不更改让其适应PHP新版本.现在PHP 7已经出发行版了,所以更改来继续使用吧.具体的更改有以下方面：

(1)将MysqL扩展的使用替换掉,改为使用MysqLi或pdo：

从PHP5.5开始,MysqL扩展将废弃了.

具体更改的文件在于includes/cls_MysqL.PHP.这是个不小的工程,文件代码太长……
