I have had some requests to write some blogs on the basics of
using PHP and MySQL together. This will not be a series for
the experienced as it will start at a level where I will go into
a lot of details but expect very few prerequisites from the
reader. If this is not you, please move on. If it is you
and you read something you do not understand, please contact me
to show me where I assumed too much.
PHP and MySQL are both in their mid twenties and
both vital in the worlds of developers. With the big
improvements in PHP 7 and MySQL 8, I have found a lot of
developers flocking to both but stymied by the examples they see
as their are many details not explained. So let's get to the
explaining!
1. Use the latest software
If you are not using PHP 7.2 or 7.3 (or maybe 7.1) then you are
missing out in features and performance. The PHP 5.x series
is deprecated, no longer support, and …
IS NULL, IS NOT NULL, truthiness among
other assertions on MySQL and PostgreSQL
People like to complain about JavaScript, how
can one thing be equal to the other, i.e. null ==
undefined evaluates to true unless you use
the triple equals ===. Other dynamic typed languages
have its peculiarities, such as Ruby where
0 == true evaluates to true, the reason
for Ruby is that considers 0 as a value and any
value evaluates to true.
How about SQL? The answer is… it depends.
Which database are you using?
Some may be more forgiving, like MySQL doing casts for you all over the place, or more strict like PostgreSQL where you can only compare the truthiness of something of the same type.

I stopped freelancing on upwork in 2011. I used to be a part-time freelancer on upwork (previously known as oDesk) from 2008 to 2011 besides my full-time job. Since 2011, I have been developing my own Indie mobile apps which is a great success for me and in my career.
I am still earning very good passive income from my own portfolio apps, today I will discuss why I have started freelancing again.

The Symfony Frame work is very popular with PHP
developers and it has a very nice Demo
Application to help novices learn the intricacies
involved. But the demo does not use MySQL. So this blog
entry is about re configuring the demo so it works with MySQL 8.
And I am using Ubuntu 18.04 LTS to you may have to adjust the
following commands to work with your operating system.
This is not difficult but there are some steps that are not
exactly self evident that this blog will show you how to get the
demo working.
Preliminaries
The first thing to do is to make sure you have PHP 7.2 or better
installed including the php7.2-intl (sudo apt-get install
php7.2-intl) package as well as the PDO connector. I will admit I
have been using PHP since it appeared and this …
I am currently working my way through the many PHP Frameworks to
see how they get on with MySQL 8. The Frameworks that can
take advantage of the MySQL Improved Extension or mysqli
can take advantage of the SHA256 Caching Authentication method.
But those that are PDO based need to use the older MySQL Native
Authentication method.
I wanted to check the PDO based frameworks and today I just
happened to be wearing the very nice Symfony shirt I received as
part of my presentation at Symfony USA. So I started with a
fresh install of Symfony. All was going well until it came
time to get it to work with MySQL 8 through Doctrine.
Doctrine
Symfony uses Doctrine as an ORM (Object Relational Mapper)
and DBAL (Database Abstraction Layer) as an
intermediary to the database. While I myself am not a big
fan of ORMs …
After installing MySQL 5.7.22 and PHP 7.1.17 on Fedora 27, you
need to install the mysqli library. You need to
verify if the mysqli library is installed. You can
do that with the following mysqli_check.php program:
Check mysqli Install<?php if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {
print 'mysqli not installed.'; }
else {
print 'mysqli installed.'; }
?>
You test preceding PHP program with the following URL in a browser:
http://localhost/mysqli_check.php
If the mysqli program isn’t installed, you can
install it as follows by opening the yum interactive
shell:
[root@localhost html]# yum shell Last metadata expiration check: 1:26:46 ago on Wed 22 Aug 2018 08:05:50 PM MDT. > remove php-mysql No match for argument: php-mysql Error: No packages marked for removal. > install php-mysqlnd > run …[Read more]
A good news for all PHP CMS users like Drupal and Joomla!, PHP 7.2.8 (available on Remi’s repo for those using rpms) supports the
new MySQL 8.0 default authentication plugin
‘caching_sha2_password‘ !
So, I’ve installed PHP 7.2.8:
And I’ve my user (here joomla) uses the …

The MySQL Document Store is a NoSQL JSON document store built
upon well known MySQL database technology. PHP runs about
eight percent of the Internet. So putting the two together
is a big priority for me. So this blog post is about getting all
this together on a Ubuntu 18.04 system.
Note that I will be teaching PHP and the X DevAPI at Oracle Code
One and hopefully in some tutorials/workshops this year.
These session will feature the X DevAPI installed on Virtual Box
images and I probably will not have time to cover these steps in
detail but I will point to this as reference material.
PHP 7.2 PHP's performance has really skyrocketed with the
seven series and the newer betas are looking very
impressive. But to use the new X Devapi you will need to
get the shared object for it into your PHP server.
