Need a variable to change depending on domain

Darkman05

In my index.php inside my <body> i have the following code, this code is used to draw the main logo for my blog from the style.css... What i want is to have a different logo displayed depending on the domain they visit my blog on...

Code:
<div id="gif">
</div>

Now if someone on my domain example1.com i want it to do
Code:
<div id="gif">
</div>

if on example2.com do

Code:
<div id="GIF1">
</div>

Basically something to change which div id it loads depending on which domain the user is on.

I have, I use it for something else, however i cant get it to work

So, try writing some PHP code using $_SERVER['HTTP_HOST']* to do this and post it here. We'll show you where you went wrong and offer suggestions.

* - Note that this is a client-driven variable; it's totally dependent on data sent from the client. Therefore, it can be empty, improperly formed, etc.

<?php

if(strpos(getenv('REQUEST_URI'), 'example1.com') !== false)
{
echo "<div id="gif">";
}
else
{
<div id="GIF1">";
}

however im getting:
Parse error: parse error, unexpected T_STRING, expecting ',' or ';'

Which is on this line it says:

echo "<div id="GIF">";

That's because you have unescaped quotes. If you use a double quote as the string delimiter, all literal double quotes in that string have to be escaped with a backslash, otherwise PHP thinks you're trying to close the string and it gets confused.

So, either escape the double quotes within the string with a backslash, or use single quotes as the string delimiter (though you'll then have to escape single quotes if any exist).

What dude? could you please show me what you mean? I'm really a newbie and it would be greatly welcomed..

See the following man page: [man]language.types.string[/man]

Since you have double quotes, Table 11-1 ("Escaped characters") should interest you. Right above that table is a coding snippet with examples of some quotes being escaped, i.e.

// Outputs: Arnold once said: "I'll be back"
echo 'Arnold once said: "I\'ll be back"';
