PHP - Unable to load dynamic library '/usr/lib64/php/modules/

Question

I am encountering the following errors when I try to run my webpage, which has a php script embedded to call a mysql database:

I have checked my php.ini file and have verified the extension_dir directive references the correct directory i.e. /usr/lib64/php/modules/

Is anyone able to shed some light on why these errors are occurring?

Solution

You should open your php.ini file located in php folder, and uncomment this line of code:

;extension=php_mysql.dll

then it will look like this:

extension=php_mysql.dll

Is php_mysql.dll only applicable to a windows installation?

@user3717786 Yes '.dll' are windows only dynamic link libraries, on Linux it'll be php_mysql.so
