A PHP script is executed on the server, and the plain HTML result is sent back to the browser.
Basic PHP Syntax
A PHP script can be placed anywhere in the document.
A PHP script starts with :
The default file extension for PHP files is ".php".
A PHP file normally contains HTML tags, and some PHP scripting code.
Below, we have an
example of a simple PHP file, with a PHP script that uses a built-in PHP function "echo" to output the text "Hello World!" on a web page:
Example

Note: PHP statements end with a semicolon [;].
PHP Case Sensitivity
In PHP, keywords [e.g. if, else, while, echo, etc.], classes, functions, and user-defined functions are not case-sensitive.
In the example below, all three echo statements below are equal and legal:

Note: However; all variable names are case-sensitive!
Look at the example below; only the first statement will display the value of the $color variable! This is because $color, $COLOR, and $coLOR are treated as three
different variables:

PHP in HTML
PHP is an HTML-embedded server-side scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dynamically generated pages quickly. NTC Hosting offers its clients high quality PHP and HTML hosting services. Our servers are configured so as to ensure maximum performance for both your HTML and PHP-based applications and the non-interruptible functioning of your websites.
PHP in HTML
When building a complex page, at some point you will be faced with the need to combine PHP and HTML to achieve your needed results. At first point, this can seem complicated, since PHP and HTML are two separate languages, but this is not the case. PHP is designed to interact with HTML and PHP scripts can be included in an HTML page without a problem.
In an HTML page, PHP code is enclosed within special PHP tags. When a visitor opens the page, the server processes the PHP code and then sends the output [not the PHP code itself] to the visitor's browser. Actually it is quite simple to integrate HTML and PHP. A PHP script can be treated as an HTML page, with bits of PHP inserted here and there. Anything in a PHP script that is not contained within tags is ignored by the PHP compiler and passed directly to the web browser. If you look at the example below you can see what a full PHP script might look like:
Recommended usage:
Hello, today is .
The code above is simply HTML, with just a bit of PHP that prints out today's date using the built-in date function. As mentioned above, all of the plain HTML in the code above will be ignored by the PHP compiler and passed through to the web browser untouched.
See how easy that is? Integrating PHP and HTML is really very simple. Just remember that at its core, a PHP script is just an HTML page with some PHP sprinkled through it. If you want, you can create a PHP script that only has HTML in it and no tags, and it will work just fine.
