help with .$_SERVER['HTTP_HOST'];

Quick question. Hoping someone can point me in the right direction.

At the top of all my pages I have:

$url_web = "http://".$_SERVER['HTTP_HOST'];

Code (markup):

So I include that in all my paths to add an absolute URL to my links

src="<?php echo $url_web.'/images/banners/choose_webdesign9.jpg';?>"

Code (markup):

This works fine on my home page but when I reference an include file on that home page, my links don't seem to recognize the $url_web.

Am I missing something somewhere? How do I get the absolute path to apply to all files?

 

It all depends on the content. If you have declared the variable within a function, it will only have a local scope. Likewise, if you've declared the variable in a global context but attempt to reference to within a local scope (i.e. function), you will be unable to do so unless you take advantage of the global keyword.

One thing you could try using is $GLOBALS['url_web'];

 

I think he tries include php script from absolute page

(

include($url_web."something.php");

)

that's wrong, you are not allowed to call absolute url in including

 

so there's no other way to set an absolute path in an include?

 

found a fix. To set an absolute path for includes use:

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

Code (markup):

Then update your php.ini in your root directory with include_path

include_path=".:path to your server/includes"

Code (markup):

 

You could, you just need allow_url_include enabled, which isn't really recommended.

 

Alex, the way I found seems to be secure. Any reason not to use what I found?
