Hi!

I'm using AJAX with PHP to read from a file and update the div's innerHTML. It works on Chrome and Firefox, but not in Internet Explorer.

I tried to use:

But I think it is useless, since I'm not refreshing the page.

if(!$newMsg || $newMsg == "") { // only reading from the file
    // do nothing
} else {
    $fileData .= "$newMsg";

    fwrite($fileHandler, "$newMsg");
}

fclose($fileHandler);

echo $fileData;

Interesting that when it enters the "else" block, it shows the file's content updated. But when it enters the "if" block, it shows the old content.
