Setcookie in include file

[alex.hughson]

I wrote a function to check valid cookies on my site, and have it on its own in a .php file

 

when I try to include the file, then call the function, I get an error "Cannot modify header information output started at..."  and then a bunch of things about how the output was started in my include file.

 

I wrote it with the assumption that include was like copying the contents of the included file in at that point.  and when i do a setcookie at the same place within the page, nothing bad happens.  Anybody have an idea how to fix this? I need to use the include file in a bunch of pages in the site.

 

Thanks

You have to make sure it sets the cookie before any output is done (i.e. an echo or HTML).

 

I had this problem before:

I was using UTF-8 or whatever encoding and it made a character at the top that I didn't see. After I deleted that character it worked (just switch to ANSI encoding).
