Function utf8_encode undefined - php

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'));

on ubuntu :
sudo apt-get install php5.6-xml
sudo service apache2 restart

The following fixed it:
sudo a2enmod xml2enc

On FreeBSD try this command
pkg install php71-tokenizer-7.1.25 php71-zlib-7.1.25

Missing BC Math or GMP extension in Laravel

I am running Laravel 5.7.14 on PHP 7.2-fpm on Ubuntu 16.04.
My code in the local environment was working fine, but once I uploaded it to the production server I got this error message: Missing BC Math or GMP extension.
I have installed both GMP + BC Math. When I run the command php -i | grep -i bcmath I get this:
/etc/php/7.2/cli/conf.d/20-bcmath.ini,
bcmath
BCMath support => enabled
bcmath.scale => 0 => 0
When I run php -m I get this:

I have restarted the server multiple times and cleared Laravel's cache but nothing's changing, I keep getting this error message.
What am I missing here? If you need more info do not hesitate to ask.
Managing multiple PHP versions is sometimes very messy.
If you are on a Linux-like system and try to upgrade PHP versions you sometimes end up with 2 versions on the same system. Not infrequently (especially when you manually have configured the previous version) the newly installed version does not get enabled to use with the webserver. Personally I've also experienced upgrading PHP and getting the apache to use the new version but as a module instead of FPM so you should also be wary of that if you are using apache since again FPM and the PHP module for apache might have different configurations as well.

Call to undefined function pcntl_wifsignaled()

I'm attempting to use the import functionality in mediawiki 1.27.0, but I'm getting the error message:
Call to undefined function pcntl_wifsignaled() in extensions/Scribunto/engines/LuaStandalone/LuaStandaloneEngine.php on line 645
I'm running PHP version 5.6.30 on Ubuntu 14.0.4 with Apache2.4.7. I've followed various bits on information to install pcntl module and to the best of my knowledge the module is operational. phpinfo reports that pcntl is enabled. I have also commented out the line in php.ini regarding disabled_functions. Below are some reports from various bits of Ubuntu to explain the current config.
Any ideas on how to fix this?

How Enable MySQLi Extension on PHP7 (LAMP / CPANEL)?

My server upgraded to PHP7 and now I am getting an error which reads "Your PHP installation appears to be missing the MySQL extension which is required by WordPress."
I have tried adding extension=php_mysqli.so to my PHP INI but that doesn't seem to help. I am on a LAMP with CentOS and Apache 2.4 with MariaDB 10.0... All was working before the update. \

PHP isn't working with SQLite

Okay, so this is my first server I'm setting up. I have a system running Ubuntu 11.10. I'm running Lighttpd and have PHP set up, but I want PHP and SQLite to work together. I installed them using:
sudo apt-get install lighttpd
sudo apt-get install php5-cgi
sudo apt-get install sqlite
sudo apt-get install php5-sqlite
PHP works fine, but any script with a sqlite command in it just returns a blank page. I turned on php error messages and ran this script:
<?php
echo sqlite_libversion();
echo "<br>";
echo phpversion();
?>
Which returns:
Fatal error: Call to undefined function sqlite_libversion()
What's gone wrong? :(
php -m produces this:
[PHP Modules] bcmath bz2 calendar Core ctype date dba dom ereg exif
fileinfo filter ftp gettext hash iconv json libxml mbstring mhash
openssl pcntl pcre PDO pdo_sqlite Phar posix readline Reflection
session shmop SimpleXML soap sockets SPL sqlite3 standard sysvmsg
sysvsem sysvshm tokenizer wddx xml xmlreader xmlwriter zip zlib
Extension in Php.ini file should be:
extension=pdo_sqlite.so
extension=sqlite.so
According to http://packages.ubuntu.com/oneiric/all/php5-sqlite/filelist the php5-sqlite contains two extension modules
pdo_sqlite.so -> http://docs.php.net/pdo
sqlite3.so -> http://docs.php.net/sqlite3
so it looks like php5-sqlite doesn't provide the module you're looking for.
If you don't have tons of legacy code I rather suggest you use PDO, esp. since the sqlite module is going to be moved from core php to pecl (nothing wrong with pecl though...):
Since PHP 5.0 this extension was bundled with PHP. Beginning with PHP 5.4, this extension is available only via PECL.
Have you added the sqlite extensions in your php.ini?
It seems this guy had the same issue: http://forum.alwaysdata.com/viewtopic.php?id=1034
The solution in that thread was to add
extension=pdo_sqlite.so
extension=sqlite.so
To php.ini, preferably under the "Dynamic Extensions" sections, but they could go anywhere.

how to install posix in php

POSIX does not appear when I run php -m cmd, however, I see it from the phpinfo() –enable-posix=shared on Linux with Plesk 9.
Basically, I can't use posix_*() functions as described at
http://www.php.net/manual/en/ref.posix.php
this shows doesn't exists:
if (function_exists('posix_getuid')) {
echo "posix_getuid available";
} else {
echo "posix_getuid not available"; // this prints in my server.
}
Could someone show me how to install it? Thank you.

I found the solution:
yum install php-process
This package enables php-posix.
While resolved, the original problem would seem to be that posix_getpwuid is not supported on Windows:
from: http://www.php.net/manual/en/function.posix-getpwuid.php
On Windows, posix_getpwuid() is not implemented
if you just want the username of the current user, you can use get_current_user().
To properly get the running user, test if function_exists('posix_getpwuid') and if not, assume you're running on Windows and call getenv('USERNAME').
In openSUSE use command zypper install php-posix for installing php-process for using php function posix_getuid
