If you use any of the above code for downloadinng files, Internet Explorer will change the filename if it has multiple periods in it to something with square brackets.  To work around this, we check to see if the User Agent contains MSIE and rewrite the necessary periods as %2E



<?php

# eg. $filename="setup.abc.exe";

if (strstr($_SERVER['HTTP_USER_AGENT'], "MSIE")) { 

    # workaround for IE filename bug with multiple periods / multiple dots in filename

    # that adds square brackets to filename - eg. setup.abc.exe becomes setup[1].abc.exe

    $iefilename = preg_replace('/\./', '%2e', $filename, substr_count($filename, '.') - 1);

    header("Content-Disposition: attachment; filename=$iefilename" );

} else {

    header("Content-Disposition: attachment; filename=$filename");

}

?>
