<?php
$advertise = $HTTP_GET_VARS['A'];
$user = $HTTP_GET_VARS['I'].&quot;.txt&quot;;
$setok = &quot;0&quot;;

if (file_exists($user))
{
$fp = fopen($user, &quot;r&quot;
echo &quot;File : $user<br>&quot;;
while ($line = fgets($fp,255))
{
if (stristr($line, $advertise))
{
$setok = &quot;1&quot;;
echo $line;
}
}
fclose($fp);
}

else
{
$fp = fopen ($user, &quot;aw&quot;
fputs($fp, $advertise.&quot;\n&quot;
fclose($fp);
}

if ($setok == '0'){header(&quot;LOCATION: continue.php&quot;}
elseif ($setok == '1'){header(&quot;LOCATION: warnign.php&quot;}
?>

Here you go!

fopen($user, &quot;r+&quot opens the file and if it doesn't exist it creates it.
Main problem was you never added a new entry once the file existed.

<?php
$advertise = $HTTP_GET_VARS['A'];
$user = $HTTP_GET_VARS['I'].&quot;.txt&quot;;
$setok = &quot;0&quot;;

$fp = fopen($user, &quot;r+&quot;
echo &quot;File : $user<br>&quot;;
while ($line = fgets($fp,255))
{
if (stristr($line, $advertise))
{
$setok = &quot;1&quot;;
echo $line;
}
}
}
// read to end of file anyway
if (setok==&quot;0&quot
{
fputs($fp, $advertise.&quot;\n&quot;
fclose($fp);
header(&quot;LOCATION: continue.php&quot;
}
else
{
fclose($fp);
header(&quot;LOCATION: warnign.php&quot;
}
?>
