Hello,
I am a newbie in php and have a problem with setting up a cookie.
The code should just verify if the user's browser has a cookie from my site, and if there is one, then increase the counter file. If not, then the counter should not be increased.
I have Xampp installed, the latest version, which means also php 5.
But, when I test the script I get from the my server the following error message:
Warning: Cannot modify header information - headers already sent by (output started at C:\Programme\xampp\htdocs\Laborator\index.php:5) in C:\Programme\xampp\htdocs\Laborator\index.php on line 55
Line 55 is where stands the setcookie() method.
I have no idea what is wrong and what this error message means.
Could someone please help me?
The code I wrote is this one:
<snip code>
From the PHP manual page for setcookie (shocking that it would have
something useful for this problem isn't it!)...
"setcookie() defines a cookie to be sent along with the rest of the HTTP
headers. Like other headers, cookies must be sent before any output from
your script (this is a protocol restriction). This requires that you
place calls to this function prior to any output, including <html> and
<head> tags as well as any whitespace. If output exists prior to calling
this function, setcookie() will fail and return FALSE."
Read the manual page: http://php.net/setcookie - everything you need is
there.
