Consider...
Making a preg pattern to capture everything between tags and then use preg_replace_callback()
process the "captured text" with the called function.
It will work; but it's a bit tricky.
Here is a similiar code snip to get you started...
$pattern= "%<[\w-/]+>%";
$text= preg_replace_callback($pattern, create_function('$matches', 'return
strtolower($matches[0]);'), $text);
This converts all tags to lowercase.
You probably should use a regular callback function rather than creating one.

Hello All,
I'm working on session and I'm getting this warning. Maybe someone can
help fixing this problem. Below is the following code.
Warning:
Warning: session_start() [function.session-start]: Cannot send session
cookie - headers already sent by (output started at
/var/www/html/bonham/cornerstone-data/property/adminlogin.php:2) in

Then I get my login fields.
Code:
<?php
session_start();
require("functlib.php");
?>

<link rel="stylesheet" type="text/css" href="/../../css/table.css">

{

$_SESSION['valid_user']=$_POST['txtUser'];
}
if(CheckAuth()==false)
{
//Code to make authentication
?>
<form method="post" action="adminlogin.php" name="login">

</form>
<?php
}
else
{
//Code if authenticated
echo "Thank you, you have been authenticated as

}
?>
<?php if(isset($_SESSION['valid_user'])){echo "<a
href=\"adminlogout.php\">Logout</a>";}?>
</body>
</html>
Function FIle:
<?php
//PHP Functions that can be included in pages
function CheckAuth()
{
if(isset($_SESSION['valid_user']))
return true;
else
return false;
}
function CheckUser($username, $password)
{
$db = new mysqli('localhost','bonham','password_goes here','bonham');
$sql="Select * from auth where username = '".$username."' and
password = '".$password."'";
$result=$db->query($sql);
$db->close();
if($result->num_rows>0)
return true;
else
return false;
}
?>
Thank for the help.

Are you absolutely sure that there is *no* output before the
session_start() in adminlogin.php?
If there is it won't work. Even a space before the first <?php, or a
Unicode BOM, or any kind of output can screw it up.

The first thing at is in my code is the start session command.

The error message indicates that your start_session() call is on line 3
and that output was started at line 2. Try pasting the first 5 lines of
that adminlogin.php script here. The other thing that is normally useful
is to have a look at the raw bytes in the file. Try this:
od -c adminlogin.php | head
from your command line. That will tell you exactly what is in the file.
Sometimes editors try to be a little bit too smart for their own good.

well, there is your answer. Your file starts with \r\n
So your PHP tag is not the first thing in your file and PHP will output
that leading \r\n.

Unless I didnt understood you.. you can easily use foreach() for that.
If you want to loop over it again and again and echo it inside you can
also just make a for() loop and in it make print_r(), if you want to use
the values of the array inside the for() you can again use foreach()
inside it just remember that after the foreach() end you need to do
reset() to the array to repeat the process again with the for().

I am building a database that houses photo, I thought everything was
going fine til I went to upload a file that was bigger then 2MB. I
check my HTML int he form I have it set to 10MB, in php.ini I have it
set to 32MB, and then in mysql I am using a longblob so shouldnt that
handle like 4GB. Anyone have anyone idea, on why files above 2MB arent
working?
