The 80/20 rule of web development

I once did this YouTube video. It was called the “Exact PHP Skills You Need to Learn to Get Paid to Code.” The idea was there’s all these things you think you need to learn or you get told by some ranting know-it-all that you need to learn… But, in reality… You only use a small fraction of those skills on a regular basis. So, I made a list of the things you’ll use most often as a PHP developer. The things that make up 90% of the coding I do. Variables, arrays, loops… That sort of thing. It’s been

Object-oriented programming in PHP

This just can get confusing as hell, sometimes. I kinda just shake my head at the “Intro to OOP” tutorials that spend the whole time talking about “polymorphism” and “encapsulation”. It’s no wonder a lot of developers hold out learning OOP. Anyway, the most important… Most fundamental… Object-oriented programming principle is much, much simpler. And, I think a big “aha” for developers. Of course, that’s probably just my naive “don’t confused the hell out of people on day 1” opinion, but who knows. Anyway, if you’ve been wanting to tackle OOP in PHP, but been afraid it’s complicated as hell…

Why so many programmers say PHP stinks

I was perusing Quora today and came across this question: “Why do so many programmers say PHP is a bad language?” Of course, that ruffled ol’ Johnny’s jimmies, so I clicked to so see some of the answers and this one made me laugh: “They’re the same people that want to ban bread knives from being sold based on the premise that they’re murder weapons. “As the saying goes – ‘PHP is so easy to learn that any idiot can use it. Far too many do.’ You can write terrible, horrible code in every programming language out there. In hard to

What they DON’T tell you about PHP

I got this Facebook comment from Jeremy: But, you won’t hear that from any PHP hater. And, I know… I’m beating this horse to a bloody pulp… But, it’s like I said yesterday: And, people asking if it’s true. So, bust out the baseball bat… I’mma keep hammering away at this. In any case, you can sit around worrying about if “PHP is dying” or whatever nonsense they dream up next… or you can make like Jeremy… And, get to work. There absolutely ARE plenty of tech jobs… And, freelance projects for PHP developers. Just gotta get out there and get

PHP usage statistics are bunk

Blah, blah… traffic… something, something. I guess that’s the strategy. When usage statistics don’t show that PHP “is like totally dying and stuff”, then we jump to whatever other statistic that fits our narrative. Anyway, here’s the rebuttal:

PHP isn’t used by REAL websites

I’ve been getting these comments more and more lately: “…let’s just consider that 80% figure, in those stats all websites count the same, so 1 WordPress blog that has not updated in 10 years and gets 10 hits a week counts the same as Youtube getting billions of hits, you see the problem with that, in reality when measured by what counts (usage/traffic) most of the web is not powered by PHP” This seems to be the new thing among PHP haters. They really want to be able to say PHP is dead. But, then there’s those pesky usage statistics

Fake PHP jobs

So, from yesterday… There’s obviously lots of PHP jobs posted out there. But, Leon asked this in response to that video: “How many companies lie about their intentions to hire, to create a false shortage, to argue for more (cheaper) foreign workers?” I’ll keep it real. My gut reaction is: “Who gives a [email protected]#?” It’s not ALL of them. I know that. And the only way you’ll really know is to apply. It just feels like an excuse to me. And, that gets my inner grumpy old man outta his chair. Buuuuuuut. Let me be civil. I looked it up.

Well, this massive list of PHP jobs should cure both: And, do let me know once you get hired. Gives me ammo for the PHP haters. 🙂 Later, John

Why is PHP still being used to create websites?

This was pretty epic. A real drop-the-mic-er. It was this answer on Quora I saw the other day from Vakrokh. The question was: “Why is PHP still being used to create new websites? Why aren’t all new sites using more modern frameworks such as Django or Rails.” I love how these guys just throw “modern” in there. As if “modern” automatically equals “better”. Anyway, here was Vahrokh’s answer: “PHP is not still being used. ‘Still’ is a word suitable to 2012 PHP, when it has been under an heavy rework and to end users / programmers it looked like it was

All the web development you’ve learned will be obsolete in a year

You ever watch the movie, Twister? There’s a scene at the end where they’re trapped in this small shed, tied to some pipes as a Tornado rolls right over them, tearing the shed to pieces. Debris everywhere. Legs flying in the air. Complete chaos. But, there’s a moment where, Helen Hunt, one of the main characters, can see all the way to the top of the tornado. And, it’s nice calm, blue sky. Almost peaceful. That’s sometimes how I feel. As I’ve talked about… all the chaos and change coming so rapidly in our industry. There’s so much to learn

Output the last row inserted in MySQLi

MySQLi makes grabbing the last inserted row easy. After running your insert query, you can do this: $id = $mysqli->insert_id; Then, you can query for that row like this: $result = $mysqli->query(“SELECT * FROM table_name WHERE ID = {$id}”); And, fetch the result as an object: $user = $result->fetch_object(); From there it’s a simple echo to output it to your page: echo $user->user_name; (Although, you’ll want to use htmlspecialchars or htmlentities to escape the output and prevent XSS attacks. But, we’ll save that for another day.) Simple. Anyway, in the newly released Module 3 of PHP 101, I show you

Connecting to MySQL with PDO

With MySQLi, it looks like this: $mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name); But, PDO is a bit different because it can interact 12 different types of databases: Oracle, PostgreSQL, SQLite, MySQL, Cubrid and several others. So, when using it you have to specify which driver you want to use. Like this: $conn = new PDO(“mysql:host={$db_host};dbname={$db_name}”, $db_user, $db_pass); Notice the “mysql:host=” bit. For different drivers, you just change out the “mysql” part. So, PostgreSQL would be: $conn = new PDO(“pgsql:host={$db_host};dbname={$db_name}”, $db_user, $db_pass); For Oracle, it’d be: $conn = new PDO(“oci:host={$db_host};dbname={$db_name}”, $db_user, $db_pass); And, so on. Nice thing is… The code

Simple input filtering in PHP

Here’s one I don’t see talked about much: $name = filter_input(INPUT_POST, ‘name’, FILTER_SANITIZE_STRING); What this does is grab the “name” element from your POST array and run it through the the filter: FILTER_SANITIZE_STRING… which removes all HTML tags from the string (since we know a person’s name doesn’t have HTML in it). It’s a really simple way of quickly filtering your data. Here’s another: if ( ! $email = filter_input( INPUT_POST, ’email’, FILTER_VALIDATE_EMAIL ) ) { die(‘Invalid email’); } This one validates the submitted email address. And, returns false if it’s invalid. Again, a very simple way of quickly validating

Why I don’t use PHP frameworks

“They all suck!” That’s straight from the horse’s mouth. Rasmus Lerdorf, the creator of PHP. He went on to say: “While they all suck. Everyone needs a framework. What everyone doesn’t need is a general purpose framework. Nobody has a general problem. Everyone has a very specific problem they’re trying to solve. And a general purpose framework, while it can solve it, it usually solves it in a way that you get so many other things that you don’t need… that ends up being done on every request.” He goes onto recommend using “targeted frameworks” for targeted problems: “Usually, I

Is PHP Dead?

Critics have been saying PHP was dead for years now. But, here it is… still tickin’ away… picking up market share and powering the web. Matter of fact, one of the harshest criticisms I’ve seen on PHP… comes from a WordPress blog. Ya know, built on PHP. But, with the rise of frameworks like NodeJS and the resurgence of Python… Has PHP seen its last days? Should you invest time learning it? Or, will it be obsolete in 5 years? I tackle that in today’s podcast. Give it a listen Plus, I snuck in a damn good “treatise” on freelancing.

Oliver Wainwright

I’m a fan. I have completed several of John’s courses. I find him very knowledgeable and he has a great delivery.

Lewis Howes

John is amazing at building membership sites. He converted one of my sites over from it’s existing (hardly working) platform over to the clean and simple to use WishList membership platform. I highly recommend using John and WishList for any of your membership site needs.

Aaron Gott

Aaron Gott

John has a particular knack for the development and training of others.

Jason Rumley

Jason Rumley

John has a habit of over-delivering on the expectations he sets up. That’s why he’s the best.

Lori Grant

John did an outstanding job on my project. I highly recommend him and look forward to working with him on future projects.

Bradley Smith

John and I have worked together on numerous projects. John is very quick and efficient and was a pleasure to work with.

Sukh Plaha

John is a fantastic and patient tutor, who is not just able to share knowledge and communicate it very effectively – but able to support one in applying it. However, I believe that John has a very rare ability to go further than just imparting knowledge and showing one how to apply it. He is able to innately provoke one’s curiosity when explaining and demonstrating concepts, to the extent that one can explore and unravel their own learning journey. Thanks very much John!

Bob Patterson

Not only is John a very talented programmer and developer, he is also an excellent communicator. He has a talent for taking complex subjects and communicating them in terms that anyone can understand. This is a rare combination. This ability has enabled me to take my skills and knowledge to the next level. Thank you John for for all that you do.

Ray Edwards

I recommend John every chance I get. If every person I worked with were as committed to excellence, punctuality, value, and unquestionable integrity… the world would be a better place. Highest recommendation.

Thabo Motsoahae

John is one of the best instructors I have come across, I learned a lot from his online tutorials.

Chris Aitken

He significantly improved my site through his expert knowledge of PHP, CSS and Javascript. Would definitely recommend John to others.

Jim DeJonge

John has a relaxed and engaging manner. His advice is solid and the explanations are well thought out.
