php : syntax code example

Example 1: php in html

Basic PHP Syntax
A PHP script can be placed anywhere in the document.

A PHP script starts with <?php and ends with ?>:

<?php
// PHP code goes here
?>
The default file extension for PHP files is ".php".

A PHP file normally contains HTML tags, and some PHP scripting code.
  
Example
<!DOCTYPE html>
<html>
<body>

<h1>Php in html</h1>

<?php
echo "Hello World!";
?>

</body>
</html>

Example 2: php syntax <<<

<?php
$str = <<<EOD
Example of string
spanning multiple lines
using heredoc syntax.
EOD;

/* More complex example, with variables. */
class foo
{
    var $foo;
    var $bar;

    function __construct()
    {
        $this->foo = 'Foo';
        $this->bar = array('Bar1', 'Bar2', 'Bar3');
    }
}

$foo = new foo();
$name = 'MyName';

echo <<<EOT
My name is "$name". I am printing some $foo->foo.
Now, I am printing some {$foo->bar[1]}.
This should print a capital 'A': \x41
EOT;
?>
