php advantages and disadvantages

php Advantages and Disadvantages

1. Advantages: open source, free, fast [Program Fast development, fast operation, quick learning of the technology itself]

Plug-ins are abundant, there are many online solutions, and there is a huge open source community that can provide help;

Cross-platform Powerful, high efficiency, image processing;

Object-oriented;

[In php4 and php5, object-oriented aspects have been greatly improved, and php can be used to develop large-scale commercial programs. . ]

PHP has strong performance, simple coordination, stability, and easy deployment;

In general, PHP can help you complete things at a low cost.

2. Disadvantages

1) The function naming is not standardized, the camel case method and the underline, and the parameter transfer positions are different. You know

2) Single Threads; PHP itself, PHP has always been a single-process program; although PHP's pthreads extension has long been available. But it is not stable enough, and it will hang up inexplicably while running; PHP extensions are all written in C, which means that if any extension has a thread competition resource control problem, the whole thing will hang up;

3) The core asynchronous network is not supported (of course there is only a synchronous non-blocking network model in Linux). But the lack of this makes it difficult to develop a network application that can withstand large concurrency. Both traditional network models and io are blocking. The basic programming approach is that a process (or thread) responds to a user connection request. Therefore, it is impossible to complete tasks like real-time online games that require thousands of network connections. Although PHP also has Libevent and eio extensions, which can make up for this to some extent, they don't feel so perfect;

4) It only supports web development, and it is inconvenient to make .exe files and desktop applications. . It is not convenient to make mobile phone programs;

5) It is not suitable for crawlers, automatic running scripts, and scientific computing projects. The basic structure of this language is not suitable, although there are many ways to achieve it.

6) Difficulty in post-maintenance. The speed-up space in the later period is quite limited.

Quoting Brother Bird [Laruence]:

said that PHP does not support multi-threading (90% of these People don’t know that the multi-threading model and the IO reuse model are comparable), it’s bad. It’s bad. It’s said that PHP does not support asynchronous (90% of these people have no idea what asynchronous means), it’s bad. It’s said that PHP is a loser language (99% of them) These people want to look for IQ superiority), bad. Every time I see this kind of argument, I feel really helpless, because there is no way you can make a person who is pretending to be stupid become smart.
