我正在codeigniter中建立一个新项目，并将所有文件上传到实时服务器后，在加载网站时出现此错误:

I'm setting up a new project in codeigniter and after uploading all files to the live server, I got this error upon loading the website:

A PHP Error was encountered

It's given line number 0 and I don't where I made the mistake. I'm not getting this error in localhost. Can anyone tell me how to fix this?

推荐答案

您正试图第二次加载php模块.它可能已经设置为加载到php.ini文件中，并且您尝试在项目内部的某个位置再次动态加载. 您可以在php.ini中注释该行并重新启动Apache，或者查找并删除可能类似于

You're trying to load the php module the second time. It's probably already set to load in php.ini file, and you try to load again dynamically somewhere inside your project. You could either comment that line inside php.ini and restart Apache, or find and delete the line that could be something like

dl('php_mysqli.dll'); // on Windows 

或

dl('mysqli.so'); // on Linux

，. php文件中的某个位置.

,somewhere inside a .php file.

更好的是，在尝试加载之前进行测试:

Better yet, test before attempting to load:

if (!extension_loaded('mysqli')) {
    dl('php_mysqli.dll');
}
