The error message told it all. Jochem was correct albiet not in the style I prefer. I had the code in an HTML page after the header. I've been a programmer for 15 years but I'm brand new to PHP. Anyone can make a rookie mistake. Thanks everyone for the help. Everyone was partially correct in assessing the problem.

I'm pasting this code from the example at php.net and getting these errors. Can anyone determine what I'm doing wrong?

<?php
// page1.php

session_start();

echo 'Welcome to page #1';

$_SESSION['favcolor'] = 'green';
$_SESSION['animal']   = 'cat';
$_SESSION['time']     = time();

// Works if session cookie was accepted
echo '<br /><a href="page2.php">page 2</a>';

// Or maybe pass along the session id, if needed
echo '<br /><a href="page2.php?' . SID . '">page 2</a>';
?>

Well, this is weird. When I copied your text and tried it myself, the error I got was:

Parse error: syntax error, unexpected T_STRING in /Users/ericgorr/ Sites/page1.php on line 9

Now, of course, there is nothing visibly wrong with line 9 ($_SESSION['animal'] = 'cat';). But, when I had my text editor show invisible characters, there were some on that line and line 10.

Do you have a text editor that can show invisible characters?

On the Mac, the one I really like (and is free) is TextWrangler (http://www.barebones.com/products/textwrangler/ ) and has this capability. This may be part of your problem. Once I got rid of the invisible characters, the example worked without any problems.

Also, are you certain there are no spaces or anything (even invisible characters) before <?php?

Whenever I've gotten a similar error in the past, that was nearly always the problem. You are welcome to compress the text file and send it to me directly so I can see exactly what it contains.


Since you're a PHP rookie, to sum it up: there can not be any output before you start a session.

When PHP interprets a file (include or otherwise) it considers anything before <?php as HTML, so it outputs it as HTML (newlines, spaces, whatever). So if you have whitespace before the <?php, then the PHP interpreter outputs it, thus the output before the session_start() error.
