When I attempt to connect to a MySQL server from PHP, I see the following error:
Deprecated: The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /path/to/filename.php on line 123
The code on the referenced line is:
mysql_connect($server, $username, $password);
I am certain that the arguments are correct, and this exact code has been working for years without problem. Indeed, I obtained it from a well-sourced tutorial on PHP.
Why is this happening?
How can I fix it?
I understand that it's possible to suppress deprecation errors by setting
error_reporting = E_ALL ^ E_DEPRECATED
What will happen if I do that?
