Use of session_start()

crusty

Newbie so this is probably a daft question.
I've tried the following which works on my PHP enabled web site.
If I try it on my home machine (WAMP Installed) I get the error.

"Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at c:\wamp\www\Mesh4Us\Htdocs\AlecHall\session1.php:2) in c:\wamp\www\Mesh4Us\Htdocs\AlecHall\session1.php on line 3"

Is there a way around this please.

Thanks. Crusty.

<?php
session_start();

if ($SESSION["last_visit"]) { echo "Date of last visit: ";
echo date("j F Y, H:i:s", $SESSION["last_visit"]); echo "<br>"; echo "Total visits: ".$SESSION["num_visits"];
} else
echo "This is your first visit";
$SESSION["last_visit"] = time();
$_SESSION["num_visits"]++;

Make sure there's no whitespace before the opening <?php tag, as well as no whitespace after the closing ?> tag. Also make sure that this file is syntactically correct (if that's not the entire file).

Unfortunately there is now "way" around this error. You might look at making sure line-endings are in "\n" format rather than "\r" or "\r\n" as that may contribute to the problem.

Another "gotcha" can be if your editor's default mode is to save your file as Unicode text, putting a byte order mark (BOM) at the beginning of the file. If so, you need to find an option to have it save without the BOM or as something like "ASCII text" or "plain text".
