[FX.php List] Sudden errors in a shopping cart

[Laura Long]

Here is some info I found, don't know if you will find this helpful or
not...

"Headers already sent" is a generic whine produced by PHP to indicate
that:

1. you are doing something that needs to send headers to the browsers
2. headers have already been sent

Session functions try to send out headers.

You need to do the session variable stuff before PHP has sent anything
to the user.

Please note that PHP can send output in non-obvious ways.  
Watch for extra carriage returns at the top and bottom of 
your include files.

And

Lots of info here...

Subject: [FX.php List] Sudden errors in a shopping cart


I'm seeing a strange error in a cart that I'm using, which was  
previously working perfectly.

Here are the errors I see:

<b>Warning</b>:  session_start(): Cannot send session cache limiter -  
headers already sent (output started at /Library/WebServer/Documents/ 
newmagic/cart/checkout2.php:1) in <b>/Library/WebServer/Documents/ 
newmagic/cart/checkout2.php</b> on line <b>1</b><br />
<br />
<b>Warning</b>:  Cannot use a scalar value as an array in <b>/Library/ 
WebServer/Documents/newmagic/cart/checkout2.php</b> on line <b>16</ 
b><br />

I have other PHP-based sites working just fine; however, this one is  
now showing these errors...

I tried echoing the error code, but it shows a zero.

I'd appreciate any help.
