PHP Statements - Introduction and Examples

PHP statements are used to calculate and output data, which is then presented to the user by a web browser. All PHP statements end with:

;

Examples:

The following PHP statement saves the text Hello World to a PHP Variable $hi. Every piece of text in PHP statements need to be wrapped in ' ' or " ".

<?php
$hi = 'Hello World';
?>

The following php statement outputs the value of variable $hi. Variables should be used without ' ' or " " in PHP statements.

<?php
echo $hi;
?>

Text and variables can also be combined in a single PHP statement like

<?php
echo 'The value of variable is ' . $hi . '. I saved it for testing';
?>

In this example, variable and text statements are combined by the notation (.).

• Text: 'The value of variable is '
• Variable: $hi
• Text: '. I saved it for testing.'

The output of the above PHP statement will be:

The value of variable is Hello World. I saved it for testing.
