PHP Syntax

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.

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

My first PHP page

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:

Example

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:

Example

$color = «red»;
echo «My car is » . $color . «
«;
echo «My house is » . $COLOR . «
«;
echo «My boat is » . $coLOR . «
«;
?>
