What is PHP An Introduction to PHP?



Definition: personal home page is a straightforward, object−oriented, interpreted, robust, relaxed, very high−performance, structure impartial, portable, dynamic scripting language. PHP has "type" key phrase much like Java's "classification" keyword. And PHP is designed such that it is 5 times faster than Java, due to the fact that there is not any virtual computer. Hypertext Preprocessor may be very quick becoming a regular, general purpose, object oriented scripting language. PHP just isn't only meant for internet purposes but also can be utilized for constructing basic applications.
Hypertext Preprocessor is the subsequent large thing after HTML considering the fact that in these days no person writes static HTML however uses PHP (generate on the fly, embedded dynamic HTML). PHP 'type−of' supercedes "static HTML". Personal home page is an extraordinarily strong scripting language. Personal home page will overtake PERL/Python and can substitute PERL/Python. Hypertext Preprocessor is the next−iteration PERL/Python scripting. PHP can do some thing PERL or Python does and surely does rather more, a lot better and far, a lot cleaner.


Personal home page stands for 'Hypertext Pre−Processor' and is a server facet HTML scripting/programming language. Personal home page is C−like internet scripting language runs on Apache, Netscape/iPlanet, and Microsoft IIS web servers. Personal home page is a instrument that allows you to create dynamic web pages. Hypertext Preprocessor−enabled web sites are handled identical to regular HTML pages and you can create and edit them the equal way you most commonly create average HTML pages. Hypertext Preprocessor lets you write simple scripts right to your HTML documents very similar to JavaScript does, besides, unlike JavaScript PHP just isn't browser−dependant. JavaScript is a consumer−part html−embedded language while personal home page is a server−aspect language. Hypertext Preprocessor is identical in concept to Netscape's LiveWire pro product and Microsoft's ASP and sun Microsystem's JSP.
PHP will not be handiest used for developing web purposes, but additionally for creating basic standalone purposes.
Hypertext Preprocessor's strength are :
personal home page is the most sophisticated technology. Other technologies PERL, Python, Tcl, VB script, ASP are older and inferior applied sciences. Even Java/JSP is not so good as PHP.



Open source• with no trouble discovered syntax• huge database connectivity• gigantic library of contributed extensions• basic reason scripting language much superior to PERL, VB script, ASP, JSP.•


Why personal home page ? PHP is the great on the grounds that of the following factors:
PERL is the "ancestor" of PHP and PERL is used for an awfully very long time (more than 25 years historical?). PHP has an abilities over PERL − Hypertext Preprocessor supports customer−side code and is easier to compile into a executable. User base of PERL is very huge. Hypertext Preprocessor tries to mimic PERL and complement the PERL science. PERL programmers like PHP! Personal home page is sincerely a "cutting-edge PERL", but with an extra identify referred to as "Hypertext Preprocessor".



Java is object−oriented however could be very slow. Java packages run very sluggish. Also Java is immensely elaborate and sophosticated technology (has many layers like JVM, JIT compiler and others). And complexity and sophostication results in problems. If there may be Linux on server−aspect then why do you want Java in servers ? And Java is extra like a procedure programming language and it's rapid to enhance in scripting languages (like Hypertext Preprocessor).
