error, zend optimizer

Compumaniac12 · #1 Nov 12th, 2006, 15:59

I had an error with phpMy admin yesterday and i installed zend optimizer to fix the problem, it worked really well, but i currently get this error whenever i try to
setcookie("DFlogin", $user, $time);

Warning: Cannot modify header information - headers already sent by (output started at c:\program files\easyphp1-8\www\logout.php:12) in c:\program files\easyphp1-8\www\logout.php on line 48

any ideas?
line 48 isnt the cookie command, im not sure what the problem is.
Syntax maybe?

Line 12 of your program generates some output - perhaps through a print or an echo statement, or perhaps because you do a ?> followed by a <?php or perhaps even because of a warning message being generated.

When that output is generated, a complete header is automatically sent to your browser based on all the called to header(), setcookie() and other header changing functions up to that point. Once the headers have been sent, you cannot send any more, by accouring to the message you're reporting, you're trying to do so at line 48.

---OOO---

The solution for you is to move the header-effecting statment at line 48 up above line 12, or to save the information you wish to output at line 12 into a variable, and output it after line 48.

In summary, once you've tipped a milk jug over and spilt all the milk, you can't put it the right way up again and magically have all the milk come back.

well i moved it up and i still get the error, so could a mysql connecting or query end headers?

why cant i just change it so it doesnt send headers untill its processed everything? (or how do i?)

If you show us the source code lines that it's complaining about, then we'll have a better chance of spotting what the errors are. Did the line numbers reported change when you made the alteration? If so, did you try the same technique on the lines newly reported?

You might well be able to disguise what is basically a flaw in you code design (in my view) using ob_start - have a look at that fucntion on the PHP web site - but really you'll do far better to sort out the issue than to hide it.

yea it changed,

it says line 11 ends head, and 35 or 37 (depending on an if statement) has the setcookie

line 11 is a <? which obviously i need there...
all this is in my html <head>
It was previously in the <body> section, but there was a php code in the header.

It worked before i installed zend optimizer...
ide rather put it aside personally, because i have more then 1 script with this same problem.

heres the source code for ya:

   } else {

   }

Include("head.php");

You need the section that includes the setcookie before you output any HTML. In other words, your <? need to go at row 1, column 1 ....

Simply move the top 8 lines of HTML down below the ?> (making sure you don't leave any white space at the top) and it should cure the problem
