A PHP script starts with <?php and ends with ?>. This script can be placed
anywhere in the document. PHP usually has HTML tags, along with some PHP coding.
PHP Syntax:
<?php
PHP Code Here
?>
Note:
The PHP file should be saved using the *.php
extension, not *.html, if saved in *.html extension then the PHP code will not be executed.
For Example:
To display an message "Good Morning" following code is executed.
<html>
<body>
<?php
echo "Good Morning";
//This is a comment
# This is a comment
/*
This is
a comment
block
*/
?>
</body>
</html>
Result:
Good Morning
In the above example the "echo" command displays the string given inside quotes. All the PHP code lines should end
with a ";". PHP supports all formats of comment's used in UNIX,C languages like "//","/**/","#".
