Bruce Eckel comments on PHP: limited to small range of applications_PHP Tutorial

The most impressive thing about PHP is this: you don’t have to understand the language in depth just to use it well. Think about it, how many languages ​​you know can do this? One of the more obvious ones is Java. Just programming a hello world requires a lot of knowledge, let alone creating a web application. But for PHP, these are out of the question.

It should be said that PHP is a little better than Perl in accessing Bad Behavior. I remember in the early days of the Web, I often heard people say that they were going to create large programs in Perl, even though they knew (and there was no way to convince them) that it would eventually fail.

On the other hand, PHP does have the ability to create some larger programs, such as Drupal. My friend Nancy Nicolaisen (also a blogger here) said she wanted to build a travel website, and I suggested she look at Drupal. She did and ended up choosing it. Because in her opinion, Drupal's user community is so excellent, it provided her with a lot of help in setting up the site and launching it smoothly.

PHP allows novices to get started quickly and directly do what they are interested in without having to worry about complicated programming theories and practices. You just do it and you get what you want on the web.

However, this is also the problem with this language. You will find that there are many examples of completely wrong PHP implementations, usually written by people who copied each other because no one knew what the problem was. One of the first examples I used was PHP's file lock. The result is that many are found, but none are correct. In fact, PHP is mainly used on databases that can handle all consistency issues, so that people don't have to think about some low-level issues. But programming languages ​​handle high-level interactions with databases and low-level interactions with file systems in the same way, so there are no "dragon is coming" signs that beginners need. I feel like there are too many people in the community who are "sitting on their laurels" and very few who truly know and understand the fundamentals. Therefore, there are situations where people in a state of ignorance break into this area that few people care about and abuse it.

After that, PHP5 appeared, which is the culmination of C++ and Java. While the power of this feature was exciting, I was increasingly concerned that people seemed to be able to have all the features without thinking through the details and the impact on the language. On the contrary, I have watched every prudent choice made in the Python language for more than ten years. Time will tell, and maybe the PHP community will figure out how to put all these features to use, but I have my doubts.

Meanwhile, on my new site which is slow to update I'm using PHP. The thing is, I only use it on a very small scale. For example, PHP can solve a low-level HTML problem that cannot be easily include files. PHP did it and made it easy to deploy my design throughout the site. Sometimes you just want to embed a little thing of your own making on the page, and this is what PHP is good at.

However, as soon as the goal becomes slightly more complex, I think it's better to move to Python. Therefore, PHP is still limited to a small range of applications, and I don't want to use it extensively.
