undefined $header variable in php class

Question

Hi,

I'm new to php so I'm not sure why this is throwing an error. The class I'm working with asks for the following (I assume I should enter something in the blank areas):

  var $headers = array(
                    "User-Agent"=>"SkipJack 1.0",
                    "Referer"=>"",
                    "Host"=>"",
                    "Accept"=>"image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*",
                    );

The problem is, no matter what I enter there, or even if I leave it blank, I get an underfined $header variable error from this line:

exec("$this->curlPath $request $headers ".$this->ROOT_HOST.$this->URLS[$this->mode],$results,$return);

Can anyone help me figure out what's going on here? And what should I enter, if anything, between the quotes? I'm not sure if it's asking me for the url of the website or skipjack's...

TIA,

JK

You have to access the object member via $this->header, not just $header.
Also the array variable will be replaced by the the string Array.

$a = array(1,2,3);
echo "... $a ...";

prints

... Array ...

and php has a curl module, you don't necessarily have to spawn another process for that.
