Information on PHP

• PHP development began in 1994 when the developer Rasmus Lerdorf wrote a series of Common Gateway Interface (CGI) Perl scripts, which he used to maintain his personal homepage. 


• The tools performed tasks such as displaying his résumé and recording his web traffic.


• He rewrote these scripts in C for performance reasons, extending them to add the ability to work with web forms and to communicate with databases, and called this implementation "Personal Home Page/Forms Interpreter" or PHP/FI.


• PHP/FI could be used to build simple, dynamic web applications.


• Lerdorf initially announced the release of PHP/FI as "Personal Home Page Tools (PHP Tools) version 1.0" publicly to accelerate bug location and improve the code, on the comp.infosystems.www.authoring.cgi Usenet discussion group on June 8, 1995.


• This release already had the basic functionality that PHP has as of 2013.


• This included Perl-like variables, form handling, and the ability to embed HTML.


• The syntax resembled that of Perl but was more limited and simpler, although less consistent.


• A development team began to form and, after months of work and beta testing, officially released PHP/FI 2 in November 1997.


• Zeev Suraski and Andi Gutmans rewrote the parser in 1997 and formed the base of PHP 3, changing the language's name to the recursive acronym PHP: Hypertext Preprocessor.


• Afterward, 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 released.


• As of August 2008 this branch reached version 4.4.9.


• PHP 4 is no longer under development nor will any security updates be released.


• On July 13, 2004, PHP 5 was released, powered by the new Zend Engine II.


• PHP 5 included new features such as improved support for object-oriented programming, the PHP Data Objects (PDO) extension (which defines a lightweight and consistent interface for accessing databases), and numerous performance enhancements.

Traffic on roads may consist of pedestrians, ridden or herded animals, vehicles, streetcars and other conveyances, either singly or together, while using the public way for purposes of travel.
Traffic laws are the laws which govern traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have developed over time to facilitate the orderly and timely flow of traffic.
Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections.
Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs.
Traffic is often classified by type: heavy motor vehicle (e.g., car, truck); other vehicle (e.g., moped, bicycle); and pedestrian.
Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate.

Traffic in English is taken from the Arabic word taraffaqa, which means to walk along slowly together.
