This script actually works except the pages are not changing, the script just keeps posting the same page over and over.  ( page=$i )


for ($i = 1; $i <= 1000; $i++) {
     
    /* RUN CODE AND SCRAPE STUFF IN HERE */
 $url2 = 'http://www.website.com/inventory/catalog.php?classID=&dept=&type=&keywords=&brandID=&price1=&price2=&age=&orderBy=BA&page=$i';
    

	$ch = curl_init(); // initialize curl handle
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_VERBOSE, 1);
	curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
	curl_setopt($ch, CURLOPT_AUTOREFERER, false);
	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,7);
	curl_setopt($ch, CURLOPT_REFERER, 'Referer: http://www.website.com/inventory/search.php');
	curl_setopt($ch, CURLOPT_URL,$url2); // set url to post to
	curl_setopt($ch, CURLOPT_FAILONERROR, 0);
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// allow redirects
	
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
	curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
	curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

	curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
	curl_setopt($ch, CURLOPT_TIMEOUT, 50); // times out after 50s

	
	
	$buffer2 = curl_exec($ch); // run the whole process
	echo $buffer2;
	if(curl_exec($ch) === false)
	{
	    echo 'Curl error: ' . curl_error($ch);
	    exit;
	}
}

"page=$i" is the  only thing changing.  You probably need some of the other values in the query string to be set to make it work.  Since they are not, you are probably getting nothing but the 'default' value or page.  Frequently, 'page' will refer to to page of a specific category.  You have not category.

If I run the same URL and change to page=2 or page=3, etc, I get different pages every time which is what I want.  The URL I have shown is a search of all of the products.  

All I am looking for is the page number to change every time a page completes.

That's confusing because that is the only thing that is changing the code you posted above.

I got it working.  Thanks for your help!  page='.$i;  instead of  page=$i.

$url2 = 'http://www.website.com/inventory/catalog.php?classID=&dept=&type=&keywords=&brandID=&price1=&price2=&age=&orderBy=BA&page='.$i;
