PHP is not working on server

问题

I bought hosting service tomorrow and from yesterday I am trying to solve problems. Problem is that PHP is not working on this server I don't know what is wrong first I used this code to connect to database

<?php
 Create connection
$con=mysqli_connect("localhost","user","pass","database");

// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
  else {
  echo "Connected";
  }

?>

It show me blank page when I upload it to server using ftp if I check source code it's also blank So I added this to check the error

ini_set('display_errors',1); 
 error_reporting(E_ALL);

then I got this error

Fatal error: Call to undefined function mysqli_connect() in /home/vidupda1/public_html/cont.php on line 6

After searching it was come to the point that mysql and mysqli extensions are not enabled in PHP.ini so I requested my hosting service provider to enable it (not replied yet)

After that I used this simple code to check if PHP is enabled or not

<html>
<title>Test</title>
    <body>
        <?php
        echo "Hello World";
phpinfo();
        ?>
    </body>
</html>

but It shows just Hello Word but not the phpinfo

So Tell me what is the acutal problem and would my problem solved after they enable these extensions ?

;extension=php_mysql.so
;extension=php_mysqli.so
;extension=php_pdo_mysql.so

回答1:

You need to enable mysqli extension by removing the ;

extension=php_mysqli.so

回答2:

I am not sure, but I believe you cannot run phpinfo() on commercial websites due to security settings. The fact that you can echo out 'Hello World' means that PHP is working. Then I believe you should wait for your host reply.

just remove the ";" and restart the apache service

回答4:

If they disabled the mysql functions, it's also possible and likely they disabled phpInfo() as well. If you succeed in getting those changes, then your code should work fine.
