authentication from server to website

[jakebur01]

Is there any way I could make php act as a browser and send a form post to a url for authentication. I want to do this so I can access and read a page within the site using php.

 

I have the reading bit already done. Now I am trying to see if I can authenticate php or the server into a specific website to access more content within the site.

Yes you can. Urlencode the username and password, then use cURL to create a connection with the other website.

Ok, I have the curl form post going to the site and I have a function the collects info within a div on a page withing the site. But, I cannot figure out how to combine the two. Or use authentication with the info collecting function.

//create array of data to be posted
$post_data['__VIEWSTATE'] = 'dDwfY6SxT5gIvWIKozYf=';
$post_data['UcLoginPage1:tbUsername'] = '4f6';
$post_data['UcLoginPage1:tbPassword'] = 'f6';

//traverse array and prepare data for posting (key1=value1)
foreach ( $post_data as $key => $value) {
$post_items[] = $key . '=' . $value;
}

//create the final string to be posted using implode()
$post_string = implode ('&', $post_items);

//create cURL connection
$curl_connection = curl_init('http://www.sfif.com/Login.aspx?HTTPReferer=Login.aspx?HTTPReferer=&Login=Error');
//set options
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);

//set data to be posted
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

//perform our request
$result = curl_exec($curl_connection);

//show information regarding the request
print_r(curl_getinfo($curl_connection));
echo curl_errno($curl_connection) . '-' . curl_error($curl_connection);

//close the connection
curl_close($curl_connection);



$item = "OP3f33";

// get DOM from URL or file
$html = file_get_html("http://smife.com/DAfil.aspx?Itefo=$item");

// find all div tags with id=gbar
foreach($html->find('div#price') as $e)
  { $num= $e->innertext;}
		$new_num = preg_replace ('~[^0-9.]~','', $num);
			$margin_num=$new_num*1.15;


			// find all div tags with id=gbar
foreach($html->find('div#qoh') as $e)
  { $qoh= $e->innertext;}

			echo "Original: $new_num<br />Margin: $margin_num<br />QOH: $qoh";
/*if($margin_num==0)
{  }
	else {mysql_query("UPDATE BOOKS set `price` = $margin_num WHERE `isbn` =$item", $db);}
*/
