PHP originally stood for Personal Home Page.
PHP is a general purpose scripting language that is widely used by the majority of the websites today.
Especially suited for web development - PHP may be embedded into HTML code or pages.
You can use it in combination with various web template systems, content management systems, web frameworks, or even executed with a Command Line Interface (CLI)
Why is PHP used on the majority of all web pages?
What are the benefits of using PHP?
PHP is used to add functionality to your website that HTML coding alone can not do.
PHP can perform different types of math calculations or Arithmetic Operators, These includes performing mathematical equations. to even calculating dates for a given year.
Here is a link showing how to create a simple PHP calculator.
Users can interact directly with PHP scripts. This might be through a a simple HTML form. Maybe letting you participate in a survey, use a "Contact Us" page or even post to any type of forum.
PHP is especially good at interacting with MySQL databases. This can open endless possibilities.
MySQL is an open-source relational database management system (RDBMS). It is the most popular database system used with PHP. MySQL is developed, distributed, and supported by The Oracle Corporation.
There are three major areas where PHP scripts are mostly used.
Server-side scripts provide an interface between the user and the website. This helps limit access to proprietary data and will keep control of the script source code.
You need a few things to make PHP scripting to work. The "PHP parser", CGI or server module, a "Web Server" and of course a "Web Browser".
Many languages can create Server-side scripts. They include but are not limited to the examples below.
PHP is primarily designed for web application development and is not commonly used for desktop application development. However, there are some tools and frameworks that allow developers to use PHP for desktop application development But if you use some advanced PHP features in your client side applications. You can write cross-platform applications. PHP-GTK is an extension to PHP, not available in the main distribution. If you are interested in PHP-GTK, visit Their Website
You can make a PHP script run without any server or browser. You only need the PHP parser to use in this way. This type of use is ideal for PHP scripts regularly executed using cron (on *nix or Linux) or Task Scheduler (on Windows). This can also be used for simple text processing tasks
This type of usage is ideal for scripts regularly executed using cron (on *nix or Linux) or Task Scheduler (on Windows). These scripts can also be used for simple text processing tasks. See the section about Command line usage of PHP for more information.
What distinguishes PHP from client side JavaScript is that the code is executed on the Web Server. It generates HTML, which is then sent to the client. The client receives the results of the PHP script without knowing what the underlying code was. You can even configure the Web Server to process all your HTML files with PHP and then there would be no way that users can tell how you are coding your website
In fact, RSH Web Services website runs completely by PHP
PHP is extremely simple for newcomers, but also offers many advanced features for those professional programmers. Don't be afraid reading the long list of PHP's features. You can jump in and start writing simple scripts in no time
Although PHP's development is focused on server-side scripting, you can do much more with it
<!DOCTYPE html>
<html lang=en>
<head>
<title>Example</title>
</head>
<body>
<?php
echo "Hi, I'm a PHP script!";
?>
</body>
</html>
Instead of a lot of commands to output HTML (as seen in C or Perl), PHP pages contain HTML with embedded code that does "something" (in this case, output "Hi, I'm a PHP script!"). The PHP code is enclosed in special start and end processing instructions that allow you to jump into and out of "PHP mode"
<?php
?>
Typical example of RSH Web's PHP file might look like:
<?php
include("assets/config.php");
include("assets/header.php");
include("assets/add/blog-what-is-php.html");
include("assets/footer.php");
?>
PHP can be used on all major operating systems, including Linux, many Unix variants, including HP-UX, Solaris and OpenBSD, Microsoft Windows, macOS, RISC OS, and no doubt others. PHP also has support for most of the web servers today
This includes Apache, IIS, and many others. And this includes any web server that can utilize the FastCGI PHP binary, like lighttpd and nginx
PHP works as either a module, or as a CGI processor, and you have the freedom of choosing any operating system and Web Server. You also have the choice of using Procedural Programming or Object-Oriented Programming (OOP), or a mixture of both
With PHP, you are not limited to just HTML output. PHP's abilities includes images, PDF files and videos
Using libswf and Ming, generated on the fly. You could also output easily any text, such as XHTML and any other XML file
PHP can auto-generate these files, and save them in the file system, instead of printing it out, forming a server-side cache for your dynamic content
One of the best and most significant features in PHP is the support for a wide range of databases. Writing a database-enabled web page is incredibly simple using one of the database specific extensions to any database supporting the Open Database Connection standard via the ODBC extension. Other databases may utilize cURL or sockets like CouchDB
PHP also has support for talking to other services using protocols such as LDAP, IMAP, SNMP, NNTP, POP3, HTTP, COM (on Windows) and countless others. You can also open raw network sockets and interact using any other protocol. PHP has support for the WDDX, a complex data exchange between virtually all Web programming languages. Talking about interconnection, PHP has support for instantiation of Java objects and using them transparently as PHP objects
