title: PHP Syntax
Basic PHP Syntax
All PHP files are saved by the extension
.php. PHP scripts can be added anywhere in the document. A PHP script starts with
<?php and ends with
<?php //PHP code goes here ?>
To print any statement in PHP we use
<html> <body> <h1>My first PHP page</h1> echo "Hello World!"; </body> </html>
NOTE: PHP statements ends with semicolon
We declare variables in PHP by adding dollar
$ sign before them.
5; echo $x; $x =
Comments in PHP
To write a single line comment in PHP we put hashtag
# or by putting
// before the comment.
# This is a single line comment // This is also a single line comment
To write a multiple line comment we start the comment with
/* and end with
/* This is a Multiple line comment. */
We can also comment out some parts of the code line.
<html> <body> // You can also use comments to leave out parts of a code line $x = 5 /* + 15 */ + 5; echo $x; </body> </html>
