php_self

I had a piece of PHP successfully running on a site for quite a while until the owner moved service provider. Now the PHP has stopped working sort of.

If the page was called for example contactus.php then a specific image was displayed otherwise a default image was shown.

Currently the last echo is getting executed. If I rename defaultimage then the image that is displayed is broken. So I know that line is being executed.
But the $PHP_Self == ' ' is getting ignored.

The site is configured for PHP4. I don't know a whole lot about PHP, so kinda stuck.

<?
		if ($PHP_SELF == 'index.php')
		{
		echo ('<img src="indeximage.gif" width="100" height="100">');
		}
		elseif ($PHP_SELF == 'contactus.php')
		{
		echo ('<img src="contactusimage.gif" width="100" height="100">');
		}	
		else
		{
		echo ('<img src="defaultimage.gif" width="100" height="100">');
		}
	?>

Bald? er, dash!

Its probably that your old server had register_globals on in php.ini, which is now not the case with the new server.

Anyway, you can access the same information from using the $_SERVER, however, this will return the path relative to the root, so as a minimum you should add a / before the filename (i.e. /index.php), or if they are in a sub-directory of the root, /directory/index.php

This should do the trick:
[PHP]
<?
if ($_SERVER == '/index.php')
{
echo ('<img src="indeximage.gif" width="100" height="100">');
}
elseif ($_SERVER == '/contactus.php')
{
echo ('<img src="contactusimage.gif" width="100" height="100">');
}
else
{
echo ('<img src="defaultimage.gif" width="100" height="100">');
}
?>
[/PHP]

Thanks Bald? er, dash!
I get it now. I had managed to figure out the global variables part and was reading up on that. I thought that php_self would give me just the file name after the domain without /
