The connection work well.
the function must see if there is any email exist in the database
but there is some problem with the text:

login.php

--- PHP Code: ---
if(user_check($email)==TRUE)
{
echo "user exist";
}
else
{
echo "user not exist";
}

--- End code ---


this page call for function.php

--- PHP Code: ---
function user_check($email)
{
$res = mysql_query("select * from users where email='$email'");
$row = mysql_fetch_array($res);
if($row['email'] == $email)
{
$email == TRUE;
}
else
{
$email == FALSE;
}
return($email);
}

--- End code ---

I made some some changes to your function.

--- PHP Code: ---
function user_check($email)
{
$res = mysql_query("select * from users where email='$email'");
$row = mysql_fetch_array($res);

  if ($row['email'] == $email)
{
return TRUE;
}
else
{
return FALSE;
}
}

--- End code ---

red wolf:
Thanks A LOT!
