Undefined function mysql_connect()

Question

I have ran aptitude install php5-mysql (and restarted MySQL/Apache 2), but I am still getting this error:

Fatal error: Call to undefined

Answer 1

I was getting this error because the project I was working on was developed on php 5.6 and after install, the project was unable to run on php7.1.

Just for anyone that uses Vagrant with ubuntu/nginx, in the nginx directory(/etc/nginx/), there is a directory named "sites-available" which contains a file named like the url configured for the vagrant maschine. In my case was homestead.app. Within this file there is a line that says something like

    fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;

There you can change the php version to the desired for that particular site.

Googled this but wasnt really able to find a simple answer that said where to look and what to change.

Hope that this helps anyone. Thanks.
