Three-day connection between php and mysql-first day

I. INTRODUCTION to PHP/MySQL
You should have heard of open source software (OSS) unless you have been on Mars for the last six to eight months. This movement has a huge impact and has attracted the attention of some large companies. Like Oralce and Informix, many companies have begun to transplant their main database products to one of the products of OSS-the Linux operating system.
If you have enough technical strength to have a complex and massive relational database system (RDBMS), it is a huge addition. However, you may have just gotten started with the database. You have just read Jay's article and decided to build a data-driven website on your own. However, you may find that you lack the necessary resources to run ASP servers or expensive database systems (and you do not need these resources ). You need something that supports Unix for free.
We recommend that you use PHP and MySQL. These two things are the best combination for developing data-driven websites. In fact, I don't need to bother to explain it. According to an unofficial survey by Netcraft, the number of hosts using PHP jumped from June 1998 in 7,500 to March 1999 in 410,000. Good, right? The combination of the two software also won the annual database product award at the Webcon98 conference and won a beautiful trophy.
MySQL is a small and flexible database server software. It is ideal for small (and not necessarily small) application systems. In addition to standard ansi SQL statements, it also supports a variety of platforms, and on Unix systems, the software supports multi-threaded running, so as to achieve good performance. For users who do not use Unix, it can run as a system service on Windows NT, or as a common process on Windows 95/98.
PHP is a script language interpreted by the server. If you have been familiar with ASP, you should be familiar with embedding code in HTML pages. The PHP code is interpreted at one end of the server as a common HTML page and sent to one end of the browser. This mode allows us to use it to complete quite complex functions.
In addition to free-of-charge (of course, MySQL also has some restrictions on license usage), the PHP-MySQL combination can also run across platforms, which means that you can develop on Windows, then it runs on the Unix platform. In addition, PHP can also run as a standard CGI process, which is an independent script interpreter or an embedded module of Apache.
If you are interested in using other database servers, PHP also supports Informix, Oracle, Sybase, Solid, PostgreSQL, and common ODBC.
PHP supports some cutting-edge technologies for Internet development. These technologies include identity authentication, XML, dynamic image generation, WDDX, shared memory, and dynamic PDF files. If you are not satisfied, PHP is very easy to expand, so as long as you have programming capabilities, you can do your best.
