Java vs. PHP

February 25, 2020

Specifically, why is Java (and .NET) used by larger companies and PHP tends to be used by small medium sized business?

Are there technical limitation in PHP 7 that prevent it from being used in big companies? Does Java and .NET share capabilities that PHP lacks? Or, is there something else going on?

What are the Best Programming Languages if you DON’T have a Degree?

June 10, 2018

Without a degree, your best chances of getting work is with a small business. Over 80% of small businesses use PHP to power their websites. So that makes PHP the #1 choice for those with no degrees.

WordPress is also widely used by small business, and WordPress is created with PHP, some JavaScript, HTML5 and CSS3. Together, these coding languages are part of what is called the web stack. Learn the web stack and you will open up MANY job opportunities.

PHP is old and sucks, no?

LOL! No! Old PHP from the 1990’s wasn’t very good, but much has changed since PHP4. Today PHP is at version 7 and it has all the ability and security as any of the other mainstream languages including:

  • JavaScript
  • Python
  • Java
  • C#
  • Ruby

So don’t let uninformed nerds convince you that somehow PHP has problems. It doesn’t.

Google Flutter vs Swift, Java and Kotlin

April 24, 2018

Mobile app development has moved toward hybrid apps, using the web stack (HTML5, CSS3 and JavaScript,) and frameworks like Phonegap or React Native.

But when it comes to the development of high demand (in terms of performance) mobile apps, using native languages like Swift for iOS and Java for Android is still the way to go. This might change with Googles Flutter framework.

PHP vs Python in 2018?

November 21, 2017

One question I get often, is which programming language should you learn?

… I’ve been getting this question for years!

Things change in the programming world, languages come and go. But the good news is that the basics, the core concepts and techniques, are 90-95% the same in all the modern programming languages:

  • JavaScript
  • Python
  • Java for web apps or Java for Andriod
  • PHP
  • C#
  • Swift
  • C++
  • C

…. What that means, is that your programming language choice, isn’t nearly as critical as you’d think. Why? Well, once you know one programming language, it is easy as apple pie to switch to another!

How to choose between PHP and Python?

The key to choosing a language comes down to two things: market viability of the programming language and what KIND of programming you want to do.

Kinds of Programming

You have many choices in terms of marketable programming languages … there is plenty of work for the languages listed above. Each language though, means a different kind of programming, and that often means a different type of person would enjoy programming language ‘A’ vs programming language ‘B’.

For example, PHP programming is focused on web development, and that’s all you will do with PHP. In fact, PHP is the most used server-side web app programming language today.

On the other hand, Python is a general purpose language that is used in many areas:

  • Data sciences
  • Ai and ML
  • Web application
  • Server automation

… Python strength is the flexibility of the language. PHP’s strength is that it is the best at building web apps, all things considered.

Choosing your language

The key is to explore a little on your part, check out which TYPE of jobs you can get with Python, and the type of jobs you can get with PHP.

Again, different programming languages mean a different type of job.

The good news is that you don’t need to worry about your choice too much, because you can always switch languages later. It’s easy to switch over, because all the above languages share about 90-95% of the same principles and concepts. The code looks different, but learning the code is the easy part.

Suggested first programming languages?

I would suggest Python if you want to get into Ai and ML, and PHP if you want to create web apps or work with WordPress in a serious way.

Hope that helps!

Learning PHP more Easily by Learning Python … what!?

September 27, 2017

PHP is probably the best web app development language out there today for a bunch of reason technical, and market oriented. But it’s not the only language out there and it doesn’t have a monopoly of good programming.

Comparing Programming Languages

An important lessons that my 20+ years of programming experience has taught me, is that one of the best ways to learn one programming language, is to learn another! By learning different programming languages, you will start to gain deeper insights about your first programming language.

Here is the key point, most modern programming languages share about 98% of the same principles and language constructs. That said, each language has their own subtle take on how they do things. So for example, PHP creates functions with this code:

function eatPeas()
echo "I love peas!";

Python (like so many languages,) has functions too. Python creates function with this code:

def eatPeas():
   print("I love peas!")

… Different code/syntax, same concept.

A funny thing happens when to express concepts in different languages: you get a better understanding of the concept. So learning how Python treats functions, will allow you to understand PHP functions better. This really becomes interesting when you get into more advanced concepts like anonymous functions, collection types and OOP.

So if you want to improve your PHP skill, learn some Python!

Note: As and added bonus, learning Python will open you up to a whole new type of programming, like Ai, ML and robotics.

Open Ended Lesson Plans and Teaching Code

April 26, 2017

After nearly 7 years of working with schools, it seems clear to me that the best way to teach code, is with an open ended lesson plan. Here’s why:

  • Learners will learn at different speeds
  • Different schools have different schedules
  • Rigid lesson plans will inventively break

Overly rigid lesson plans can easily be derailed … I hear about it all the time. Once that happens, teachers are scrambling to get things back on track. The other approach is to use a flexible lesson plan that allows for variability in the classroom:

  • Student misses a few days.
  • Student is talented and moving fast
  • Student is struggling and needs more time
  • School gets cancelled a few days for whatever reasons …

A curriculum designed for reality

Instead of a set of highly structured lesson plans that can be hard to implement, we provide a fun and outcome focused set of courses that give students the freedom to learn at their own pace.

… A student missing a few days school, working more quickly or more slowly than other students, won’t break the flow of the classroom.

The goal is that students learn to code, and that they understand the basic concepts behind the code. Luckily, this can be achieved very easily and early on in the courses. For students who are high performing and have zipped ahead of the class, you have plenty of course material in StudioWeb, where they can learn another language (Python, SQL, PHP) or build more elaborate web sites and apps.

PHP Courses for College in 2017 and 2018

April 25, 2017

One of the reasons PHP is a good language to teach server side programming with, is because it is relatively easy to setup a PHP environment on each student’s workstation. With free apps like MAMP and WAMP, you can install a fully functional PHP installation with MySQL, Apache and it comes with an easy to use control panel to manage the servers.

With this 1-click install running, students will be able to explore concepts like:

  • web servers
  • database servers
  • http directory and how it impact server side code processing

… And more.

StudioWeb’s interactive PHP courses teach not only the fundamentals of programming, we also have included key project based courses (crud with PHP, PHP tag cloud) that allow students to see PHP used in a real-world programming context.

Teachers benefit from the interactive training in StudioWeb, since the StudioWeb app tracks student performance including:

  • Time on each question
  • Question attempts
  • Right and wrong code attempts

As such, we generate accurate grades by course, chapter and even the lesson – all presented in simple to read tables. This means that teachers will instantly know how well students have grasped each subject.

PHP is a powerful language that students can almost immediately use in the real world to build great web apps. StudioWeb itself is a PHP app, and after 6 years of refinement, our student outcomes just keep getting better and better.

Every entrepreneur and business owner is familiar with the term ROI. However, when it comes to their business websites they have little or nothing to say when talking about ROI.

The overwhelming amount of information in the digital world can trick even the sharpest mind. There seems to be one to many online marketing strategies out there and it can be hard to choose what really works and how to take advantage of it.

The pace with which technology advances is incredible and in the last decades, it has gone insane. There is digital innovation everywhere and there is so much of it that we can barely keep up with what is changing within our houses. No one seems to watch TV or play board games anymore. All we hear about in the living room is Netflix, Xbox, and countless different names of apps with so many purposes that you get lost just thinking about it.

It can get even messier when we go into our screens and into the business world. From the beginning of the internet to nowadays a lot has changed and even though many aspects of the digital world have become more comprehensible to the average business person, at the same time, an incredible number of new marketing possibilities came into the market making it a little confusing. The good thing is that in the end, to have success online, your business needs to focus on just a few things primarily that will make the most difference in the long term.

Take advantage of the tools available

There are many tools available out there to get a website. There is no need to pay $20,000+ for a business website anymore. All you need is the right tools and the right person, and that could well be yourself.

One of the all favorite internet geek tools today is website builders. They are very easy to use and in a matter of minutes, anyone can make a webpage. Among the options available in the market, is a wonderful free website builder with very interesting tools. The only cost involved is for hosting, domain names and other features such as custom email addresses. The price ranges approximately from $9.8 to $21.8 depending on your company’s needs.

By using SITE123’s free website builder, you get a nice cost reduction and that makes it easier for you to get your investment back. Along with other strategies, it will lead to greater ROI.

Provide excellent customer service

There are two things that are extremely fundamental for every business: sales and customer service. The first one guarantees your cash flows and the second ensures you that the customers will be coming back for more. It cannot be different with a website. You must provide excellent customer service in order to retain your clients and make sure they will come back to you when then need more of the product or service you offer.

Traditionally, customer service is offered on-site, on the phone, by mail and email. The digital world offers other possibilities now. By using chat plugins, your clients will be able to contact your company in real-time through a little chat window. They just click and start talking to you. To add a chat plugin to your website on, click on “SETTINGS” and then “PLUGINS” on the left side menu of the website builder.

Capture leads and nurture them

One of the greatest tools in traditional business strategy is capturing leads and nurturing them. This can be brought to the digital world as well. There are quite some ways you can generate leads online. The most common of them is subscription boxes. They are everywhere and seem to be working very well. A recent Forbes article mentioned that if you have a subscription service, capture and nurture leads, you could get an increase in sales of 20%. What a return on investment that can bring you over time.

Take advantage by adding a subscription box to your website. On SITE123’s website builder, just go to the “FOOTER LAYOUTS” options under “DESIGN” and insert a subscription box to your website.

Send out newsletters

Among the possibilities you have for nurturing your leads and actually converting them into customers is one that has been very misused but is now regaining space: newsletters. A few years ago, subscribing to a newsletter from most websites was like buying a ticket to hell. It was so annoying – they would flood your mailbox with all kinds of products, services, fake discounts and so on. And it would not stop there. All of a sudden, emails coming from all over the world with links to all kinds of sketchy websites would arrive: your email address had been somewhere somehow sold on a bundle with thousands of other email addresses.

Thanks to the common sense of some professionals, newsletter have once again become secure and interesting as the websites now seem to send only relevant content and do not just try to sell to you every day at all cost. And customers like it. A recent article by Business Insider reads that 60% of CEO’s read newsletters.

Your business can jump in and use this powerful tool for informing your leads about your business and industry. It is the era of information now and you can also send some interesting facts related to your business or industry. Your clients may like the content and bond to your company putting you one step from retaining them as customers.

On SITE123’s management panel there is an option for managing a mailing list with your leads and sending out newsletters to them.

Keep an eye on new online marketing strategies

Above we outlined a few of the most important online marketing strategies. There is much more out there and every day new powerful tools come into play and some of them could take your business into a huge leap. It is all about staying up to date.

Thankfully, there are many places you can go for help such as forums and blogs with valuable content to inform and teach you about the latest trends in online marketing. Also, remember to sign up for newsletters that you think could bring you interesting information. Using simple smart tools and keeping yourself informed about new effective opportunities to throw into your marketing mix, it is almost guaranteed that you will have great success with your website.
