<head>
<title><?php echo $title; ?></title>
</head>
<body>
<?php $title = "Music Wallpapers"; print $title; ?>
</body>
any body knows how to display a variable before it is defined?
You can't display a variable that is not yet defined! PHP files are parsed top to bottom, so it needs to be defined above where you want to use it. So, may be you can just change the order...
<?php $title = "Music Wallpapers"; ?>
<head>
<title><?php echo $title; ?></title>
</head>
<body>
<?php print $title; ?>
</body>

Likewise, it should also work by including an external file. But I would guess there is something wrong with your head_tag.php file if it is not?
By including it the way you are, it would need to be something like:
<?php
echo '<title>'.$title.'</title>';
?>
You are missing the colon (;) in the include statement? which you posted initially.
The semi-colon (statement separator) is not reqd at the end of the include since there is only 1 statement.

<?php
echo '<title>'.$title.'</title>';
?> what is this? so i would have to put this on the head_tag.php file
instead of this
<title><?php echo $title; ?> </title>
?
I.e, don't do it like this:
<?php include("http://www.example.com/index/source/modules/php/head_tag.php") ?>
Rather, do it like this:
<?php include("head_tag.php") ?>
Including the file via the filesystem and not through an http call will allow your $title variable to work. It's on you to figure out the location of the file on your system.
i think i cannot do it the way you say
<?php include $_SERVER['DOCUMENT_ROOT'].'/source/modules/php/head_tag.php'; ?>
Are you familiar with the values available in the _SERVER variable?
Dump phpinfo() to see - [php.net...]
Very useful...
