PHP is a scripting language originally designed for producing dynamic web pages. It has evolved to include a command line interface capability and can be ud in standalone graphical applications.
通草的功效While PHP was originally created by Rasmus Lerdorf in 1995, the main implementation of PHP is now produced by The PHP Group and rves as the de facto standard for PHP as there is no formal specification. PHP is free software relead under the PHP Licen, however it is incompatible with the GNU General Public Licen (GPL), due to restrictions on the usage of the term PHP.
雪地寻踪PHP is a widely-ud general-purpo scripting language that is especially suited for web development and can be embedded into HTML. It generally runs on a web rver, taking PHP code as its input and creating web pages as output. It can be million websites and 1 million web rvers.
PHP originally stood for Personal Home Page. It began in 1994 as a t of Common Gateway Interface binaries written in the C programming language by the Danish/Greenlandic programmer Rasmus Lerdorf. Lerdorf initially created the Personal Home Page Tools to replace a small t of Perl scripts he had been using to maintain his personal homepage. The tools were ud to perform tasks such as displaying his résumé and recording how much traffic his page was receiving. He combined the binaries with his Form Interpreter to create PHP/FI, which had more functionality. PHP/FI included a larger implementation for the C programming language and could communicate with databas, enabling the building of simple, dynamic web applications. Lerdorf relead PHP publicly on June 8, 1995 to accelerate bug location and improve the code.This relea was named PHP version 2 and already had the basic functionality that PHP has today. This included Perl-like variables, form handling, and the ability to embed HTML. The syntax was similar to Perl but was more limited, simpler, and less consistent.
Zeev Suraski and Andi Gutmans, two Israeli developers at the Technion IIT, rewrote the parr in 1997 and formed the ba of PHP 3, changing the language's name to the recur
sive initialism PHP: Hypertext Preprocessor. The development team officially relead PHP/FI 2 in November 1997 after months of beta testing. Afterwards, public testing of PHP 3 began, and the official launch came in June 1998. Suraski and Gutmans then started a new rewrite of PHP's core, producing the Zend Engine in 1999. They also founded Zend Technologies in Ramat Gan, Israel.
On May 22, 2000, PHP 4, powered by the Zend Engine 1.0, was relead. On July 13, 2004, PHP 5 was relead, powered by the new Zend Engine II. PHP 5 included new features such as improved support for object-oriented programming, the PHP Data Objects extension (which defines a lightweight and consistent interface for accessing databas), and numerous performance enhancements. The most recent update relead by The PHP Group is for the older PHP version 4 code branch. As of August, 2008 this branch is up to version 4.4.9. PHP 4 is no longer under development nor will any curity updates be relead.
In 2008, PHP 5 became the only stable version under development. Late static binding h生活如此多娇
牛肉的做法as been missing from PHP and will be added in version 5.3. PHP 6 is under development alongside PHP 5. Major changes include the removal of register_globals, magic quotes, and safe mode. The reason for the removals was becau register_globals had given way to curity holes, and magic quotes had an unpredictable nature, and was best avoided. Instead, to escape characters, magic quotes may be substituted with the addslashes() function, or more appropriately an escape mechanism specific to the databa vendor itlf like mysql_real_escape_string() for MySQL.
PHP does not have complete native support for Unicode or multibyte strings; Unicode support will be included in PHP 6. Many high profile open source projects cead to support PHP 4 in new code as of February 5, 2008, due to the GoPHP5 initiative, provided by a consortium of PHP developers promoting the transition from PHP 4 to PHP 1397 语文第一课It runs in both 32-bit and 64-bit environments, but on Windows the only official distribution is 32-bit, requiring Windows 32-bit compatibility mode to be enabled while using IIS in a 64-bit Windows environment. There is a third-party distribution available for 64-bit Windows.
PHP is a general-purpo scripting language that is especially suited for web development. PHP generally runs on a web rver, taking PHP code as its input and creating web pages as output. It can also be ud for command-line scripting and client-side GUI applications. PHP can be deployed on most web rvers, many operating systems and platforms, and can be ud with many relational databa management systems. It is available free of charge, and the PHP Group provides the complete source code for urs to build, customize and extend for their own u.
PHP primarily acts as a filter, taking input from a file or stream containing text and/or PHP instructions and outputs another stream of data; most commonly the output will be HTML. It can automatically detect the language of the ur. From PHP 4, the PHP parr compiles input to produce bytecode for processing by the Zend Engine, giving improved performance over its interpreter predecessor.芋子饺
