This solves all of that – we don’t need to manually search for the file to include, we just use the use keyword to import the library into our code. As mentioned above, PHP will still serve the index.php file as we’re still sending data to the same URL the form is on. One is within an HTML page, so PHP is used to “add” stuff to the HTML which is manually defined in the .php file. In modern PHP codebases that use a framework, files are generally loaded automatically so you’ll have less need to use the above functions. The above syntax includes the test.php file from the current folder, the file where this code is.
- Is syntax is very easy to learn and implement in the application so this very popular in the world to develop websites using PHP?
- Moreover, PHP is a cross-platform language, which means that developers may use any primary operating system – Windows, Linux, macOS – to perform coding.
- We’re mixing a bunch of code and we could separate the form request handler from the code that generates the form.
- Still, strong support for PHP from Microsoft and Apple as part of the integrated development environments such as Visual Studio and Xcode is certainly significant.

For dates, it’s common to use libraries that offer a lot more functionality than what the language can. There are many different kinds of errors, like parse errors, runtime fatal errors, startup fatal errors, and more. The first two are minor errors, and they do not stop the program execution. Require does the same, but if there’s any error doing so, the program halts.
Today, PHP is one of the top five in-demand programming languages. Still, strong support for PHP from Microsoft and Apple as part of the integrated development environments such as Visual Studio and Xcode is certainly significant. Now, enterprise-ready IDE’s provide excellent support for PHP along with C# and Swift.
However, the distant perspectives of PHP raise some concerns regarding its future viability in web development. For example, Python already attracts more new developers than PHP, and this trend is not likely to change soon. Besides, Python deals with some highly demanded features, such as machine learning, better than PHP due to the presence of specialized libraries. At this rate, PHP needs a significant leap in its evolution to catch up with Python, otherwise its popularity will continue to wane. Over the years, the concerns regarding the security of PHP-based products still persist due to several reasons. One of them is the open-source nature of PHP, which means that the possible code vulnerabilities become the common knowledge after they have been found.

So you access a URL with your browser, Chrome or Firefox or Safari, and the HTTP server responds with some HTML content. Those languages are compiled and the compiler generates an executable program that you then run.
Where to Learn PHP?
Moreover, PHP has a large number of available libraries and frameworks that extend its capabilities even further. The most popular examples of such frameworks are Laravel, Symfony, Phalcon, Zend Framework, and Yii.
