this quick function will check if the page is home or not good if you want something on the other pages and something just on the home page in the header or that kind of thing.

i have tested this in the header

<?php
if( is_home() ) {
    echo "home<br>";
} else {
    echo "not home<br>";
}
?>

and here is the inline version incase you would prefer to add html inbetween these tags

<?php if( is_home() ) { ?>
    home
<?php } else { ?>
	not home    
<?php }?>
