Ok, i'm going insane here. I'm very new to php so i bought Beginning PHP 4 to learn. I'm Trying to get the code from chapter 10 File and Directory Handling to work. However if i use their code (avialable via download) all i get is the following error...

as far as i can tell the thml_header() is only declared once. What am i missing? I'm a bit peeved that their code isn't in working order. There's really no excuse for that.

There might be a file that includes the function, or html_header() might be a new function to PHP included in a version of the language that came out after this book was released.

Beginning PHP 4 is an old book, the code in Beginning PHP 4 was written with an older version of PHP 4. The code in this book really looks more like PHP 3 code. Beginning with PHP 4.2.0 PHP made some radical changes, of course this was well after Beginning PHP 4 was released, so you can hardly blame the authors for it, since you're using a much newer version of the language than they did. And if you hadn't realized, there is a Beginning PHP 5 book out now.

Regards,
Rich

Ah...very good point. I guess I bought the PHP 4 book just because I new PHP 5 wasn't as prevalent yet. I know PHP 5 is a major updgrade. However, i'm guessing it's still backward compatible? Meaning my current PHP 4 code should work if I install 5 on the server?

Cheers,

Yes, PHP5 is backward-compatible.
