Complementing previous answers, you could do :

<?php
$line = file('alert.txt');
$valrec = $line[0]; //if "1" the fancybox appear
if($valrec == 1){
?>
<script type="text/javascript">
jQuery(document).ready(function($){
    $.fancybox({
        href: "alert.php",
        type: "iframe"
    });
}); //ready
</script>
<?php
}; // closes if
?>
