This question already has an answer here:
After updating to PHP5.6 and Apache server 2.4 I started using PHP in FPM mode. The migrated PHP code shows the following error every time a call to database is made:
[06-Oct-2015 09:38:07 UTC] PHP Fatal error: Call to undefined function mysql_connect() in /var/www/html/loadscript.php on line 40
My MySQL is the same version as before, so I am thinking that another version has to be installed to match my updated configuration. What am I missing?
