I just installed PHP and Apache on my home PC. When I try to call function mysql_connect I get:

fatal error: call to undefined function mysql_connect.

I have loaded php.ini where I have uncommented lines extension=php_mysql.dll and extension=php_mysqli.dll and changed extension directory to extension_dir = "C:phpext" - which is the directory where files php_mysql.dll and php_mysqli.dll are. How can I fix this problem?

Output of phpinfo():



After looking at your phpinfo() output, it appears the mysql extensions are not being loaded. I suspect you might be editing the wrong php.ini file (there might be multiple copies). Make sure you are editing the php file at C:phpphp.ini (also check to make sure there is no second copy in C:Windows).

Also, you should check your Apache logs for errors (should be in the logs directory in your Apache install.

If you haven't read the below, I would take a look at the comments section, because it seems like a lot of people experience quirks with setting this up. A few commenters offer solutions they used to get it working.

Another common solution seems to be to copy libmysql.dll and php_mysql.dll from c:PHP to C:WindowsSystem32.

  1. Locate the correct php.ini file (check phpinfo() if in doubt)
  2. Locate the line saying


    and make sure it is uncommented (no ; in front)

  3. Save
  4. Restart web server

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:



use MySQLi or PDO

$con = mysqli_connect('localhost', 'username', 'password', 'database');
