    PHP Syntax

    PHP Syntax

    Basic PHP Syntax

    A PHP scripting block always starts with <?php and ends with ?> . A PHP scripting block can be placed anywhere in the document.

    On servers with shorthand support enabled you can start a scripting block with <? and end with ?>.

    However, for maximum compatibility, we recommend that you use the standard form (<?php) rather than the shorthand form.

    <?php ?>

    A PHP file normally contains HTML tags, just like an HTML file, and some PHP scripting code.

    Below, we have an example of a simple PHP script which sends the text "Hello World" to the browser:

    <html> <body> <?php echo "Hello World"; ?> </body> </html>

    Each code line in PHP must end with a semicolon. The semicolon is a separator and is used to distinguish one set of instructions from another.

    There are two basic statements to output text with PHP: echo and print . In the example above we have used the echo statement to output the text "Hello World".

    Comments in PHP

    In PHP, we use // to make a single-line comment or /* and */ to make a large comment block.

    <html> <body>

    <?php //This is a comment /* This is a comment block */ ?>

    </body> </html>
