Fatal error: Call to undefined function mysqli_connect()

Solution

• Find out which php.ini you are using. If none, create one from php-development.ini or else and paste it in let say c:\php5\
• Unescape extension_dir like this:

  ; Directory in which the loadable extensions (modules) reside.
  ; http://php.net/extension-dir
  ; extension_dir = "./"
  ; On windows:
  extension_dir = "ext"

• Unescape these two extensions:

  extension=php_mysql.dll
  extension=php_mysqli.dll
