I'm making this program and I'm trying to find out how to write data to the beginning of a file rather than the end. "a"/append only writes to the end, how can I make it write to the beginning? Because "r+" does it but overwrites the previous data.
$datab = fopen('database.txt', "r+");
Here is my whole file:

<head>
<title>Facebook v0.1</title>
<style type="text/css">
#bod{
margin:0 auto;
width:800px;
border:solid 2px black;
}
</style>
</head>
<body>
<div id="bod">
<?php
$fname = $_REQUEST['fname'];
$lname = $_REQUEST['lname'];
$comment = $_REQUEST['comment'];
$datab = $_REQUEST['datab'];
$gfile = $_REQUEST['gfile'];
print <<<form
<table border="2" style="margin:0 auto;">
<td>
<form method="post" action="">

</td>
</table>
form;
if((!empty($fname)) && (!empty($lname)) && (!empty($comment))){
$form = <<<come
<table border='2' width='300px' style="margin:0 auto;">
<tr>
<td>
<span style="color:blue; font-weight:bold;">
$fname $lname :
</span>
$comment
</td>
</tr>
</table>
come;
$datab = fopen('database.txt', "r+");
fputs($datab, $form);
fclose($datab);
}else if((empty($fname)) && (empty($lname)) && (empty($comment))){
print" please input data";
} // end table
$datab = fopen('database.txt', "r");
while (!feof($datab)){
$gfile = fgets($datab);
print "$gfile";
}// end of while
?>
</div>
</body>
</html>
