The php semantic is close to other programming languages like (C/PERL ...) .PHP script code must be between the <? ?> or <?php ?> brackets.

Code:

<?php
 #php code here 
 
?> 
 html code here like any html page

<? 
 #php code here 
?>
 

'#' is for comments

Hello world php

You can include your php code within the html tags

Code:

<html>
<head>
<title>Hello world php</title>
</head>
<body>
<?php
echo "Hello World!";
?>
</body>
</html>

the output of this is

Code:

Hello World!

Semicolon
In the above example you may be see that the php line is ends with semicolon ';' .
for example again

Code:

<html>
<head>
<title>Hello world php</title>
</head>
<body>
<?php
echo "Hello World! ";
echo "Hello World! ";
echo "Hello World! ";
echo "Hello World! ";
echo "Hello World! ";
?>
</body>
</html>

the output is :

Code:

Hello World! Hello World! Hello World! Hello World! Hello World!

White Space

whitespace is ignored between PHP statements

Code:

<html>
<head>
<title>Hello world php</title>
</head>
<body>
<?php
echo "Hello World!"; 
 



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

the output is :

Code:

Hello World!Hello World!
