PHP Error: “Call to undefined function mysqli_connect()”

Question

In PHP I'm getting this error:

Call to undefined function mysqli_connect()

I checked my php.ini file and there is no ; in front of extension=php_mysql.dll or extension=php_mysqli.dll .

I think the I am getting this error because my figuration File (php.ini) Path is C:\\Windows . How would I change it to C:\\Apache2.2\\php\\php.ini ?

Answer 1

On Ubuntu machines you can try:

sudo apt-get install php5-mysql

since the basic PHP5 install does not include the mysqli_connect function.

Answer 2

You can set the path using PHPIniDir in .htaccess or your server config.

ie.

PHPIniDir "C:/Apache2.2/php"

You won't have to recompile PHP if the extension gets loaded correctly (so make sure your extension_dir is correct), just make sure you restart Apache after you made these changes.

Answer 3

您需要使用此库的扩展重新编译PHP。
