PHP is a hypertext preprocessor. The abbreviation of hypertext preprocessor is a server-side and cross-platform HTMI. Embedded scripting language. Its unique grammar has the characteristics of C language, Java language and Perl language. It is a widely used open source multi-purpose scripting language, especially suitable for Web development.
Characteristics of 1.2 PHP development language
PHP is a language that was born, used and developed on the Internet, and it has been branded as free development since its birth. At present, thousands of websites of individuals and organizations at home and abroad are learning, developing and perfecting it in various forms and languages, and constantly releasing the latest applications and research results. PHP can run in most operating systems, including Windows and Linux, and is often used together with free Web server software Apache and free database MySQI. The combination of these three technologies is called "golden combination" because it is used on the I.inux platform with high cost performance. The following features will be introduced. PHP development language.
1. Come on
PHP is a powerful CGI scripting language. Its syntax is a mixture of new syntax in C, Java, Perll and PHP styles. It can execute web pages faster than CGI, Perl and ASP, which is the outstanding feature of its 1.
Step 2 be practical
Because PHP is a new object-oriented and completely cross-platform Web development language, it is very practical from the perspective of developers and economy. PHP has a simple grammatical structure and is easy to get started. Many functions can be realized by only one function, and many institutions have successively launched IDE tools for developing PHP.
3. powerful
PHP has extremely powerful functions in the process of Web project development, and its implementation is relatively simple, mainly as follows.
Can manipulate all kinds of mainstream and non-mainstream databases, such as MySQL, Access, SQL Server, Oracle, DB2 and so on. Among them, PHP and MySQL are an excellent combination and can run across platforms.
You can exchange information with lightweight directory access protocol.
It can communicate with many protocols, including IMAP, POP3, SMTP, SOAP and DNS.
Use POSIX and Perl-based regular expression libraries to parse complex strings.
It can effectively manage XML documents and create and call Web services.
Step 4 be selective
PHP can adopt two development modes: process-oriented and object-oriented. Developers can consider the scale and future maintenance of the developed website to choose the mode they should adopt.
MySQL database is the most widely used in the process of PHP developing Web. PHP version 5.0 or above not only provides the early MySQL database manipulation function, but also provides MySQL extension technology to manipulate MySQL and database, so that developers can consider the way to manipulate MySQL database from the aspects of stability and execution efficiency.
Most functions of PHP can be realized in many ways, and developers can choose the best way according to their proficiency in mastering knowledge.
