Before marking duplicate please understand that I have tried all the solutions mentioned in other similar question.
I have hosted my website in amazon ec2. I have done everything possible to make mysqli_connect work, still didn't find solution for it.

在php.ini中尝试了以下操作

Have tried following in php.ini

1. 评论:extension=msql.so extension=php_mysqli.dll
2. 重新启动apache2服务器.

代码如下.

在使用前我已经定义了那些变量.

where i have defined those variables before using.

<?php
$con = mysqli_connect($mysql_host,$mysql_user,$mysql_password);
?>

我得到的错误是

致命错误:未捕获错误:调用/var/www/html/connect.php:2中未定义的函数mysqli_connect()

Fatal error: Uncaught Error: Call to undefined function mysqli_connect() in /var/www/html/connect.php:2

请支持我.

推荐答案

我终于得到了解决方案. 我做错了三件事.

I finally got the solution. There were three things I was doing wrong.

1. 由于我在linux中工作，因此需要取消注释msql.so而不是取消注释mysqli.dll.
2. 第二，我没有评论/etc/php/7.0/apache2/php.ini，而是改为在/etc/php/7.0/cli/php.ini中进行这些更改.
3. 第三，目录('lib/php/')中没有名为msql.so的文件，而是mysqli.so.因此，将php.ini中的名称从msql.so更改为mysqli.so确实对我有用.

1. Since i am working in linux, uncommenting msql.so was required rather then uncommenting mysqli.dll.
2. Second, I was uncommenting in /etc/php/7.0/apache2/php.ini, but instead i was to make those changes in cli i.e /etc/php/7.0/cli/php.ini.
3. Third, the file named msql.so was not there in the directory ('lib/php/'), instead it was mysqli.so. Therefore changing the name from msql.so to mysqli.so in php.ini did the trick for me.

希望这有一天会有所帮助.
