PHP is one of the tools that allows you to generate dynamic web pages. PHP stands for Hypertext Preprocessor (PHP). PHP is completely free. You can learn more from the official website of PHP ([url])[/url].
The application of PHP in personal web projects has increased significantly. According to Netcraft's report in 1999 10, there are 93 1 122 domains and 32 1 128 IP addresses using PHP technology.
There are many advantages to using PHP. Of course, the known disadvantage is that PHP, as an open source project, has no commercial support and its execution speed is slow (until PHP4). But PHP mailing lists are very useful unless you are running something like Yahoo! Or a very popular website like Amazon.com, you won't feel that the speed of PHP is different.
The syntax of PHP is similar to C, Perl, ASP or JSP. PHP is too simple for people who are familiar with one of the above languages. On the contrary, if you know more about PHP, you can easily learn several other languages.
It only takes you 30 minutes to master all the core language features of PHP. You may already know HTML very well, and even you already know how to make beautiful websites by editing and designing software or by hand. Because PHP code can be added to your site without obstacles, you can easily add PHP to make your site more dynamic when designing and maintaining your site.
PHP can be compiled with functions connected to many databases. PHP and MySQL are now an excellent combination. You can also write your own peripheral functions to access the database indirectly. In this way, when you change the database you use, you can easily change the encoding to adapt to this change. PHPLIB is the most commonly used basic library, which can provide general transaction requirements.
As mentioned earlier, PHP has entered a period of rapid development. It may be difficult for a non-programmer to extend the additional functions of PHP, but it is not difficult for a PHP programmer.
PHP provides classes and objects. Web-based programming needs object-oriented programming ability very much. PHP supports constructors, extracting classes, and so on.
Traditionally, the interaction of web pages is realized through CGI. The scalability of CGI programs is not ideal because it opens an independent process for each running CGI program. The solution is to compile interpreters (such as mod_perl, JSP) of languages that are often used to write CGI programs. PHP can be installed like this, although few people want to install it in CGI like this. Embedded PHP is more extensible.
In order to be more suitable for web programming, PHP developers have developed many popular basic libraries, which contain easier-to-use layers. You can use PHP to connect to most databases, including Oracle, MS-Access and Mysql. You can draw pictures on flies, write programs to download or display emails. It can even complete network-related functions. Most importantly, you can choose which functions you need for the version of PHP you installed. To quote Xterra from Nissan, PHP can do anything you want it to do, it can do anything!
Therefore, PHP is not a video format. Maybe you didn't get the desired video file correctly, so you can't play it.
