I would recommend using cURL to actually make the call then DOM to parse. The advantage to using DOM is allowing you a little bit of leeway when it comes to changes on the website. The advantage to curl being extended flexibility and the ability to return errors. This will require quite a bit of studying on your part in order to determine the correct values to look for. The below code should get you started: Show
Once you have $output, you can parse with DOM. Few ways you can go about it, I recommend XPATH queries From there you return it. I would instead recommend parsing http://themoneyconverter.com/RSSFeeds.aspx <?php
$CurlStart = curl_init();
curl_setopt ($CurlStart, CURLOPT_URL, "http://www.gamersfirst.com/warrock/?q=Player&nickname=soldier");
curl_setopt ($CurlStart, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($CurlStart, CURLOPT_REFERER, $url);
curl_setopt ($CurlStart, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; nl; rv:1.9.1.11) Gecko/20100701 Firefox/3.5.11");
curl_setopt ($CurlStart, CURLOPT_HEADER, 1);
curl_setopt ($CurlStart, CURLOPT_FOLLOWLOCATION, true);
$source = curl_exec ($CurlStart);
curl_close ($CurlStart);
$a=preg_match("/>Level:.*.\n.*.>([0-9]*)</",$source,$b);
$Level = $b[1];
echo "Level: $Level";
?>
Here one main concern is the data gets exposed in address bar of the browser and can be easily accessible by using browser history. So it is not a good idea to pass sensitive data like password through the URL to different pages or different sites. Passing variable with data to different pages Here is an example of passing data through URL within a site.The address of page2.php can be replaced with any site name and the same data can be passed to another site running in any server. Like this Passing data outsideYou can see in the above case the values can be posted to another site. Note that after the page name we are using question mark ( ? ) to start the variable data pair and we are separating each variable data pair with one ampersand ( & ) mark.  Submitting form values through GET methodA web form when the method is set to GET method, it submits the values through URL. So we can use one form to generate an URL with variables and data by taking inputs from the users. The form will send the data to a page within the site or outside the site by formatting a query string.Submitting a form through POST methodBy post method of form submission we can send more number or length of data. Sensitive information like password does not get exposed in URL by POST method, so our login forms we should use POST method to submit data. This is how we collect data submitted by POST method in PHP
Read more on difference between GET and POST method of form submission Collecting data submitted by either GET or POST methodIf a page is receiving a data which can come in any one of the method GET or POST then how to collect it ? Here we are not sure how to collect the data. So we will use like this.Every scripting language pages has its own way of receiving the data from the URLWhile receiving the data based on the server settings the values will be available to the pages. Here in a server running PHP will have to see the global settings of the server on how to collect the data.Passing data within the site using URLThe same principle is used like above to send the data within the site using URL. A query sting can be formatted with a link or a form can be used with get method to pass variables between pages.Passing the data between the site through URLLike above data can be passed to different pages of sites using URL . The best use is directly linking to a page dip inside another site by formatting a query sting. Like thisPassing variables through query stringIn many applications we need to pass variables through query string. For example we want to display the product details where product ID is to be passed in query string through a variable. The product ID can be collected from a table so we don't know what is the value but we can use the variable which stores the product ID.For example let us say we have collected product id from the product table. Read the tutorial on how to collect data from table. Our link with query string will have something like this. Chang of data while passing through URLThere is a problem in sending data other than plain text through browser. Empty space and some characters like & if present in the data , will create problem. To maintain the data integrity we have to encode the data before sending them though URL and then decode them again to get back the original data. In PHP encode command is used and in ASP VBScript the command is Server.URLEncode(string)Security issues while posting data through URLThe most common type of security problem in using data from URL is injection attack. We must sanitize the date before using inside our script or generating any query to manage database.Declaring variables Cookies to store Information How can I transfer data from one website to another in PHP?Look into PHP's curl extension.
