append PHP code to HTML input placeholder?

I want to append a PHP function that shows the user his/her IP within an inputs' placeholder. I've never seen anything like this been done before so I'd like to just see if it's possible or not.

My thoughts right now is to do something along these lines:

$('input').attr(placeholder,function(){
$('input').append('<?php $variable ?>');
});

then run the PHP code through here some how. If someone can shed some light on this I would be very grateful!

If you want to do it in PHP you can make a function to retrieve the IP of the user then echo the script in your page:

<?PHP

function getUserIP()
{
    $client  = @$_SERVER['HTTP_CLIENT_IP'];
    $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
    $remote  = $_SERVER['REMOTE_ADDR'];

    if(filter_var($client, FILTER_VALIDATE_IP))
    {
        $ip = $client;
    }
    elseif(filter_var($forward, FILTER_VALIDATE_IP))
    {
        $ip = $forward;
    }
    else
    {
        $ip = $remote;
    }

    return $ip;
}


echo "<script type='text/javascript'>

    $('input').attr(placeholder,function(){
    $('input').append('".getUserIP()."');
    });
    </script>";
?>

try this:

$('#inputID').attr("placeholder","<?php echo $variable; ?>");

And if you want to append to all inputs:

$(":input").attr("placeholder","<?php echo $variable; ?>"); should do the work
