why learn php

This course is right for you if you want to learn how to use PHP as I assume no previous programming experience. But you must have the basic the knowledge of following technologies for web development as well. PHP can handle the forms, such as – collect the data from users using forms, save it into the database, and return useful information https://cryptominer.services/ to the user. PHP tutorial for beginners and professionals provides in-depth knowledge of PHP scripting language. Our PHP tutorial will help you to learn PHP scripting language easily. You might not be a developer, but maybe you’re faced with developer-esque questions like, “What language is the best for my new website?

Of them all, and has been around for almost as long as PHP. Both languages have huge communities and are highly versatile, though only JavaScript allows for full-stack development. On the other hand, PHP is easier to learn and maintain, so using it could mean lower development costs. Of course, some of the points we’ve listed above could be applied to other programming languages. So here are just a few of the main alternatives to PHP to help you choose which is best suited to your project or organization. PHP has driven the demand for development languages year over year.

PHP Tutorial

Also, PHP can connect to many different databases, from the open-source MariaDB, to Microsoft SQL Server. If you use MariaDB or MySQL, just like PHP these are free and you don’t need a licence to use them. PHP supports various databases like Oracle, MySQL, and MS Access and is designed to interact with other services using protocols such as HTTP, LDAP, POP3, IMAP, NNTP, SNM, and COM.

Another important use of PHP can be for creating desktop Graphical User Interface based applications. Prominent tools that allow scripting in PHP are PHP-GTK 2 and ZZEE PHP GUI, which compile PHP into.exe that can run on its own. No matter how small or big a business is, online selling is an indispensable part of any venture today.

  • To the final user, who looks at the browser and has no idea of the code behind the scenes, there’s no difference at all.
  • I am also tempted to say that if you need a database you should use a framework or ORM that would save you security issues with SQL injection.
  • You can use the built-in exceptions provided by PHP but you can also create your own exceptions.
  • PHP can be used to create any kind of web application you can think of, from simple dynamic websites, to eCommerce sites that use shopping carts, content management systems, and so on.
  • Putting your code live is also as simple as copying the files from your computer to the live server.
  • Require does the same, but if there’s any error doing so, the program halts.

PHP can be used to create various means of data representation like charts, graphs, and scatter-dot plots by using tools such as Image_Graph. This feature is commonly used across client-side ecommerce websites, desktop applications, and various other applications where data must be presented succinctly and graphically. Also prominent among applications of PHP is its use to manipulate images. The different formats of output images can be jpeg, gif, wbmp, xpm, and png. This is an essential prerequisite for creating robust websites and web applications. In an age of intimidating, large-scaled tech stacks, PHP remains widely used in the web development niche.

Such flexibility greatly facilitates the development process by making it faster and less expensive. The popularity of PHP gave rise to the numerous community of developers, a fraction of which can be potential candidates for hire. The large number of available specialists results in high competitiveness and lower demanded wages, which is beneficial for reducing development costs.

Include loads the content of another PHP file, using a relative path. For example when a property is set, or accessed, or when the object is cloned. This performs a shallow clone, which means that references to other variables will be copied as references – there will not a “recursive cloning” of them. Inside the child class we can use $this to reference any property or method defined in the parent, as if they were defined inside the child class.

How to Handle Exceptions in PHP

Instead you return a value from the function, and the outside code that calls the function will take responsibility for updating the outside variable. Variables defined outside How to Become a Robotics Engineer From Scratch in 2022 Columbia Engineering Boot Camps of the function are not accessible inside the function. You can use functions to group together multiple instructions or multiple lines of code, and give them a name.

  • Also, the PHP community is vast – from forums on the official website, to communities like Stack Overflow, you’re never far from professional help and advice.
  • You can just write the code in a text file, then access your script in a web browser.
  • Applying training materials, projects, and access to other PHP developers will accelerate your understanding and application of PHP.
  • There have been questions in the past about PHP security, though it is important to note that it is not inherently more or less secure than other programming languages.

Numerous web-based applications and Facebook apps are scripted in PHP too. PHP is a widely used server-side programming language that’s become increasingly fast and powerful over the years. PHP works well with HTML and databases, making it a great language for anyone interested in building dynamic web applications.

Should I learn PHP?

The public keyword is the access modifier and sets the property to be publicly accessible. Get started learning about functions in PHP so you can create your own reusable blocks of code. The second reason for PHP having a bad reputation regarding its security is the low entry barrier for novice programmers. As a result, a number of websites and apps are developed by inexperienced coders, trainees, or even hobbyists. The shoddy results of their work contribute to the rumors and facts regarding overall bad security and performance of PHP.

We’re now done talking about the object oriented features of PHP. Other magic methods include __call(), __get(), __set(), __isset(), __toString() and others. I previously listed the few functions we commonly use for strings. After the first “Hello World”, it’s time to dive into the language features with more details. Yours might be different depending on your configuration. Using MAMP you can find it in the user interface of the application.

However, if you refer to a development company with a good reputation and a team of experienced and certified specialists, you shouldn’t worry about the security of your product. The answer to that question is so far unclear – but that doesn’t mean it’s bad news. PHP is a ‘veteran’ programming language and is used by 80% of the top 10 million websites in the world, so needless to say it has significant community support.

This file exists, and PHP code is executed server-side before Apache sends the page back to the browser. The process will depend on your operating system, but once you’re done with the installation, you will have a “MAMP” application installed. Of course, you can set up each piece on its own if you like, and many tutorials explain how to do that.

We’ll see how to use them to perform some array operations later. Note that as the next example shows, arrow functions have automatic access to the variables of the enclosing scope, without the need of use(). This enforces a good programming practice as we can be sure the function does not modify external variables and cause “side effects”. There are a lot more built-in functions you can use to work with strings. We have this opening/closing structure because we can embed PHP inside HTML. PHP is a scripting language, and its goal is to be able to “decorate” an HTML page with dynamic data.

While PHP is a powerful tool supported by a large community and plentiful reference documentation, there are easier programming languages for web apps. For this reason, novice developers prefer learning Python as their first language and rarely consider adding PHP to their skillset. Currently, PHP dominates the web development segment, but this most likely will change in the future. There are also extensions available to help make creating new sites in PHP simpler, including authentication, location services, and encryption.

If you’re using MAMP on a Mac it’s by default /Applications/MAMP/htdocs. You can follow this handbook with any kind of PHP installation method, not just MAMP. Then to do anything non-trivial you’ll need a database, like MySQL.

The vendor folder contains the library just installed and its dependencies. It allows you to easily install packages into your projects. JSON is a portable data format we use to represent data and send data from client to server. This works for simple use cases, but of course for intensive data you will need a database.
