how to include text through PHP

[adil]

hey all,
I have a text and few links that I need to be at every webpage of the website.
How can I do that ?
Do anyone have any idea ?

<?php include($DOCUMENT_ROOT . "/includes/stuff.xyz"); ?>That goes into every page where you want stuff included.

Then, create the file stuff.xyz, and place it in your includes/ folder (you can create any path you want to your includes - the path in the code above is just an example).

thanks alot

I suppose you could always use frames, but I am totally against frames in every way possible. You could also use CSS "content", although I along with most people here disagree with it. I would suggest the PHP route to be the best.

:hi: A few comments to that:

Number 1:
In PHP 4.2.0 and later, the default value for the PHP directive register_globals is off. This is a major change in PHP. Having register_globals off affects the set of predefined variables available in the global scope. For example, to get DOCUMENT_ROOT you'll use $_SERVER['DOCUMENT_ROOT'] instead of $DOCUMENT_ROOT

Number 2:
Use single quotes '...' instead of double quotes "...". Only use double quotes if you use variables within them. PHP searches double quotes for variables thus making it slower.

$foo = bar;
print '$foo'; // this would print '$foo'
print "$foo"; // this would print 'bar'

So the correct way would be:
<?php include($_SERVER['DOCUMENT_ROOT'].'/includes/stuff.xyz'); ?>

Good information. Thanks jos :)

Hey,

Out of curiosity what is the difference between:
<?php include("./file.html"); ?>

and

<?php include($_SERVER['DOCUMENT_ROOT'].'/includes/stuff.xyz'); ?>

I'm not sure of the exact difference, Nick, but I do believe the latter will not work with PHP3. We did a recent server migration, which involved a PHP upgrade, and as a result, some customers who were using the latter method that you describe above were having problems. Reverting to the first method solved the problem.

Hey,

<?php include("./file.html"); ?> and

<?php include($_SERVER['DOCUMENT_ROOT'].'/includes/stuff.xyz'); ?>
This is actually more complicated than it seems.

./ means "in the same directory". But which "same directory"? You would think it means "the same directory as the file including it", and most of the time you're right. Regardless, it does not mean the "root" directory of your site.

If the file was included by *another* file, the "same directory" could be different than you think. This often arises when you include libraries in other directories which themselves then include other files or try to open ini files, etc. etc.

$_SERVER[DOCUMENT_ROOT] is the absolute base directory of your site. It *never* hurts to include it as the start of a path, because it completely disambiguates the ".." and "." path issue.

Also, remember that PHP paths are file system paths on your server, NOT the same as the paths used (x)html, which are SITE-based.

Hope this didn't confuse things further!

Also, remember that PHP paths are file system paths on your server, NOT the same as the paths used (x)html, which are SITE-based.Meaning, if you didn't specify DOCUMENT_ROOT (which is quite safe and very handy), you would not use http://www.domain.com/ as your root for an absolute path, you would use something like /home/user/public_html/ as your root path.

exactly right.

Thanks for sharing this information. I really like your way of expressing the opinions and sharing the information. It is good to move as chance bring new things in life, paves the way for advancement, etc. But it is well known to everyone that moving to new location with bulk of goods is not an easy task to move or shift from one place to other place because I have experienced about that and I face the problem like that. There I go to village near to my city faced that problem there.
