我对ezSQL_mysql和ezSQLcore有问题，它可能是PHP的不兼容版本，我分享下面的代码。我应该使用哪个版本的Php或应如何定制mysqli？ （我的php版本5.6） 代码：

我对ezSQL_mysql和ezSQLcore有问题，它可能是PHP的不兼容版本，我分享下面的代码。我应该使用哪个版本的Php或应如何定制mysqli？ 我应该怎样安排？感谢您的帮助。
答案 0 :(得分：0)
问题是在您的实现中您有：
function escape($str)
它们具有核心功能：
function escape()
它们需要完全匹配。因此，我建议将核心文件中的签名更改回escape($str)
