Common misunderstandings in PHP programming

Regarding the misunderstandings of PHP programming, we will clarify them. Some misunderstandings are worth pondering, while some are just baseless. Anyway, let’s take a look at these misconceptions.
1. PHP is an object-oriented language, but it is not based on OOPS
This is a completely incorrect understanding, especially for Java programmers, who think that PHP is not based on OOPS; but they will find many object-oriented features, such as interfaces , methods, abstract objects, etc. To be honest, the initial version of PHP did not have many object-oriented features, but PHP 5 adds many object-oriented technologies. More importantly, you may be curious why Bootstrap code becomes so simple in PHP. This is due to the combination of PHP and OO.
2. PHP cannot implement specific functions
This misunderstanding sounds vague, but many developers believe that PHP cannot implement other functions such as memory access. But the fact is that PHP is an extensible language. You only need to write an extension in C or C++ and integrate it. Or, you don’t need to create one. There are hundreds of extensions available online, and you can use them directly as needed.
3. PHP is not safe
Since you think it is unsafe, why not write safe code for it. I admit that there is a lot of unsafe code in PHP, but as programmers, we should try to write reliable and safe code.
　If you compare PHP with .NET, PHP will definitely fail. But if you're a skilled programmer, you don't need security "help." Includes day-to-day security concerns, but if their paths are dynamically generated, then you have to be careful. Of course, it might become safer if you master all the commands.
4. Not suitable for large applications
The reason why a language can be used to build large and complex applications must have a certain degree of reliability and high performance, and the scalable PHP does not meet this requirement. But if the application architecture you design and develop is stable, what's the problem with application performance and scaling?
　The fact is that some well-known websites are designed using PHP, such as Facebook, Wikipedia, and Yahoo!, etc., and they all work very well.
5. PHP can only be used for website development
　 Indeed, it is very common to use PHP for website development. But the command line interface (CLI: Command Line Interface) allows applications to run on non-Web servers.
　Although some applications have high CPU requirements, they can still be developed and run in PHP by executing the PHP CLI. What's more, if you want to develop desktop applications using PHP, just use Windows-specific extensions.
6. The development process is slow
I really don’t know where this misunderstanding came from. It's possible that the PHP code you wrote is messy and filled with a lot of MySQL statements (which, although they make sense, really shouldn't be there). In fact, PHP has a large number of frameworks for developers to use. Proper use of them will achieve twice the result with half the effort and greatly reduce development time. So, don't complain about being slow.
7. Professional developers don’t use PHP
Regarding this misunderstanding, there are various opinions, such as PHP is a piece of cake for beginners, it is for those who don’t want to take development seriously, etc. Of course, I have to admit that PHP does not make sense in some aspects, but such misunderstandings are really ridiculous. If there are many web applications here that are developed using PHP, then imagine that developers who have always been rigorous are staying away from PHP, which is completely wrong.
8. Performance issues
　 This is a technical issue, not a misunderstanding. Everything has good and bad aspects. Performance optimization has always been a topic of discussion among developers. In fact, for applications with low performance, they may be filled with a lot of junk code, such as implicit conversions, useless modules, lack of overloading of operation methods, etc., which will affect the performance of PHP applications. But it ultimately depends on how you use the language to create a stable and fast application.
9. Cheap applications mean low quality
In a market environment where open source is gradually becoming mainstream, free and open source are the biggest advantages of PHP. This means that most developers with expertise can provide development services and also save costs for clients. But this does not mean that there is a problem with quality, and high-performance applications can also be developed.
As programming languages continue to develop and grow, various misunderstandings will follow, but no matter what, some false rumors will be dispelled without attack. As the saying goes, practice is the only criterion for testing truth, so before choosing to believe or not, it is best to test and confirm it yourself.
