Hello friends! I'm relatively new and still have a lot to learn about Linux in general. I've done a ton of research on this problem, and can't seem to find a clear-cut solution (other than advising to run on a Windows machine, which is not an option).

I have a php script that is trying to establish a connection to a database using sqlsrv_connect(). I am on CentOS 7, using PHP 7.1, with no luck. The exact issue I get when executing my php file in question is as follows:

PHP Fatal error: Uncaught Error: Call to undefined function sqlsrv_connect() in /var/www/html/gocare/DBTest.php:8

After some online research, I looked up the location of mysqli.so and mysql.so and added the following to my php.ini configuration file.

extension=/usr/lib64/perl5/vendor_perl/auto/DBD/mysql/mysqli.so
extension=/usr/lib64/php/modules/mysql.so

Now I get the same error as before, but with a few extras when executing the DBTest.php. I've confirmed these files exist at these locations, and have no idea why I'm getting these errors. I've done "systemctl restart httpd" to restart httpd.

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/perl5/vendor_perl/auto/DBD/mysql/mysqli.so' - /usr/lib64/perl5/vendor_perl/auto/DBD/mysql/mysqli.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysql.so' - /usr/lib64/php/modules/mysql.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Fatal error: Uncaught Error: Call to undefined function sqlsrv_connect() in /var/www/html/gocare/DBTest.php:8
Stack trace:

Any advice that can be given would be greatly appreciated, I think I might be in a little over my head here!

Hi and welcome to LQ,
You didn't say how you've installed the driver?
Undo what you've done already and follow the instructions about RHEL7 and PHP-7.1 here.

Regards

Thank you, I will give that a try and update.

I did what you asked and followed those directions, works like a charm now! Thank you very much!

Glad to see you've made it.
You may mark the thread as solved from the thread tools on top of the page.

Cheers
