Setup your environment and create your first page.

Edit scotlanti.info file specified under as in example below: # grep 'scotlanti.infone' /opt/plesk/php//etc/scotlanti.info To bring these together, he wrote the first web browser and web server, tools . The PHP interpreter returns the results of the executed PHP code, along with the within the PHP tags, the built-in date function displays the current day of the.
In terms of keywords and language syntax, PHP is similar to the C style syntax.

Data types[ edit ] PHP stores integers in a platform-dependent range, either a bit or bit signed integer equivalent to the C-language long type. Unsigned integers are converted to signed values in certain situations; this behavior is different from other programming languages. Floating point numbers are also stored in a platform-specific range. They can be specified using floating point notation, or two forms of scientific notation. These are typically created by functions from a particular extension, and can only be processed by functions from the same extension; examples include file, image, and database resources.
Order is preserved in lists of values and in hashes with both keys and values, and the two can be intermingled. Custom functions may be defined by the developer: In this manner, normal PHP functions can be used, for example, as callbacks or within function tables.
Function calls must use parentheses, with the exception of zero-argument class constructor functions called with the PHP operator new, in which case parentheses are optional.PHP & MySQL Tutorial 42 - Date and time
Such a function is a first-class object, meaning that it can be stored in a variable, passed as a parameter to other functions, etc. So, for example, if a parameter's type is int, PHP would allow not only integers, but also convertible numeric strings, floats or booleans to be passed to that function, and would convert them.
In the new approach, objects are referenced by handleand not by value. PHP 5 introduced private and protected member variables and methods, along with abstract classesfinal classesabstract methodsand final methods.

There are special interfaces that allow objects to interact with the runtime system. As you probably know, the browser consults an additional Internet service called the Domain Name Service DNS to find its associated IP address and then uses it to communicate with the computer. The web server, having received the request, fetches the home page from its hard disk.
With the home page now in memory, the web server notices that it is a file incorporating PHP scripting and passes the page to the PHP interpreter. The web server returns the page to the requesting client, which displays it.
On the server side, progress was being made on the Common Gateway Interface CGI using scripting languages such as Perl an alternative to the PHP language and server-side scripting—inserting the contents of one file or the output of a system call into another one dynamically. Once the dust had settled, three main technologies stood head and shoulders above the others. Under Ajax, web pages perform data handling and send requests to web servers in the background—without the web user being aware that this is going on.
No doubt the symbiotic nature of PHP and MySQL helped propel them both forward, but what attracted developers to them in the first place?
The simple answer has to be the ease with which you can use them to quickly create dynamic elements on websites. MySQL is a fast and powerful, yet easy-to-use, database system that offers just about anything a website would need in order to find and serve up data to browsers. When PHP allies with MySQL to store and retrieve this data, you have the fundamental parts required for the development of social networking sites and the beginnings of Web 2.
To facilitate this, you may wish to prepare a file called example. Using PHP, you have unlimited control over your web server. Whether you need to modify HTML on the fly, process a credit card, add user details to a database, or fetch information from a third-party website, you can do it all from within the same PHP files in which the HTML itself resides.
Also, a flat file can get only so big before it becomes unwieldy to manage—not to mention the difficulty of trying to merge files and perform complex searches in any kind of reasonable time.
And MySQL, being free to use and installed on vast numbers of Internet web servers, rises superbly to the occasion. It is a robust and exceptionally fast database management system that uses English-like commands. The highest level of MySQL structure is a database, within which you can have one or more tables that contain your data. One command that you might use to do this is: It is well suited, however, to database queries, which is why it is still in use after all this time.
To do this, you could issue a MySQL query such as: For example, you can join multiple tables according to various criteria, ask for results in a variety of orders, make partial matches when you know only part of the string that you are searching for, return only the nth result, and a lot more. This means you can save the results in arrays for processing and perform multiple lookups, each dependent on the results returned from earlier ones, to drill right down to the item of data you need.
Instead, a quick Ajax call can pull in and update a single element on a web page, such as changing your photograph on a social networking site or replacing a button that you click with the answer to a question. For example, not only can you style any HTML element to change its dimensions, colors, borders, spacing, and so on, but now you can also add animated transitions and transformations to your web pages, using only a few lines of CSS.
This flexibility not only lets you style your HTML precisely, but it can also, for example, provide built-in hover functionality to animate objects as the mouse passes over them. For example, there was still no simple way to manipulate graphics in a web browser without resorting to plug-ins such as Flash. And the same went for inserting audio and video into web pages.
Plus, several annoying inconsistencies had crept into HTML during its evolution. So, to clear all this up and take the Internet beyond Web 2.
It was called HTML5 and it began development as long ago aswhen the first draft was drawn up by the Mozilla Foundation and Opera Software developers of two popular web browsers. Although websites come and go at great speed, the underlying software is developed slowly and carefully, and so the stable recommendation for HTML5 is not expected until after this edition of the book has been published—in late And then guess what?
Work will move on to versions 5. So learning everything you can about it now will stand you in very good stead. Applications Including two new rendering technologies: But now things have gone full circle, and you can use either version of these element types.
In the case of this book, that means the Apache web server. To do this, each element a web client encounters in an HTML page is also requested from the server, which then serves it up.
They can all be generated by programs such as PHP scripts.
