Disable a php code only in homepage -

i want add php code in cms site's header, dont want run in homepage. because causes errors!!

already tried code, somehow still runs code , shows error

    <?php $homepage = "/"; $currentpage = $_server['request_uri']; if($homepage==$currentpage) { } else {code} ?>

it not error, if php code run in home page header , call database query, home page not assigned work for. trying add additional feature.

error page

this code

<?php     $item = the_item(); $imgsd = 'store_avatar( ( !empty( $item->image2 ) ? $item->image2 : store_avatar( $item->store_img ) ) )';  ?>

try more (might work):

<?php     $homepage = array("/","/index.html","/index.php");     $currentpage = strtolower($_server['request_uri']);     if(!in_array($currentpage, $homepage)) {             //code goes here     } ?>

p.s. : try indent code when post on internet.
