You can't do this using PHP only since is a server-side execution (the page / scripts are rendered in the server before the user can see anything on his browser)

You should put your script in a separate file, and then do an AJAX call.

To display the loading image follow this (jQuery framework needed)

```
// SHOW YOUR LOADING GIF HERE
$('#result').load('yourscript.php', function() {
 //HIDE YOUR LODAING GIF HERE
});
```

I've tried the following code, which given me exactly what I want. the page is displaying a "loading.gif" while loading the php script, and hide it when the script is finished. This is using JQuery.

//$tr_arname=$_REQUEST['arname'] -> is the variable i've got from previous PHP page.

<body onload="loadingAjax('myDiv');">

<script>
var arname="<?php $tr_arname=$_REQUEST['arname']; echo "$tr_arname"; ?>";
function loadingAjax(div_id)
{
    $("#"+div_id).html('<center><img src="images/loading.gif"><br><br><font color="#006699" face="arial" size="4"><b>Loading arerror.log <br><?php echo "$tr_arname"; ?> <br>Please Wait ...</b></font></center>');
    $.ajax({
        type: "POST",
        url: "ThePHPScriptPage.php",
        data: "arname=" + arname,
        success: function(msg){
            $("#"+div_id).html(msg);
        }
    });
}
</script>

<div id="myDiv"></div>
</body>

You can request your php file from another web page using AJAX. Then you have your javascript display a loading.gif until the server answers the request.

You could use jQuery for this: http://api.jquery.com/load/
