Function utf8_encode undefined

I have Ubuntu 16.04 installed, which comes with PHP 7 by default; but I ended up installing PHP 5.6 as well, and I have apache using 5.6.

When I went to run a project of mine, it told me the following:

PHP Fatal error: Call to undefined function utf8_encode()

I read through a bunch of posts where others have had this issue, and tried installing different extensions; but nothing has helped.

My understanding, was that that function would be packed with PHP (4,5,7) by default.

Any ideas?

* Update *

I did try the following, and it came back false.

var_dump(is_callable('utf8_encode'));

Here are the installed mods/extensions:

Was your PHP compiled with --disable-xml? Check your phpinfo(). – deceze♦
You should have a package called php5-xml or something similar. This function is part of the PHP XML parser – Machavity♦
Maybe a silly question, it's installed but is it enabled? Try a2enmod / check mods-enabled folder to triple check! – rjdown
Oooh I think I got it. I did sudo a2enmod xml2enc, and that fixed it. – xil3
Wahey! Kinda weird it doesn't get enabled by default :| – rjdown
