found something now
<?php
// Defining the basic cURL function
function curl($url) {
// Assigning cURL options to an array
$options = Array(
CURLOPT_RETURNTRANSFER => TRUE, // Setting cURL's option to return the webpage data
CURLOPT_FOLLOWLOCATION => TRUE, // Setting cURL to follow 'location' HTTP headers
CURLOPT_AUTOREFERER => TRUE, // Automatically set the referer where following 'location' HTTP headers
CURLOPT_CONNECTTIMEOUT => 120, // Setting the amount of time (in seconds) before the request times out
CURLOPT_TIMEOUT => 120, // Setting the maximum amount of time for cURL to execute queries
CURLOPT_MAXREDIRS => 10, // Setting the maximum number of redirections to follow
CURLOPT_USERAGENT => "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1a2pre) Gecko/2008073000 Shredder/3.0a2pre ThunderBrowse/3.2.1.8", // Setting the useragent
CURLOPT_URL => $url, // Setting cURL's URL option with the $url variable passed into the function
);
$ch = curl_init(); // Initialising cURL
curl_setopt_array($ch, $options); // Setting cURL's options using the previously assigned array data in $options
$data = curl_exec($ch); // Executing the cURL request and assigning the returned data to the $data variable
curl_close($ch); // Closing cURL
return $data; // Returning the data from the function
}
// Defining the basic scraping function
function scrape_between($data, $start, $end){
$data = stristr($data, $start); // Stripping all data from before $start
$data = substr($data, strlen($start)); // Stripping $start
$stop = stripos($data, $end); // Getting the position of the $end of the data to scrape
$data = substr($data, 0, $stop); // Stripping all data from after and including the $end of the data to scrape
return $data; // Returning the scraped data from the function
}
$scraped_page = curl("http://thewebpage"); // Downloading IMDB home page to variable $scraped_page
$scraped_data = scrape_between($scraped_page, "<title>", "</title>"); // Scraping downloaded dara in $scraped_page for content between <title> and </title> tags
echo $scraped_data; // Echoing $scraped data, should show "The Internet Movie Database (IMDb)"
just gotta try sort the tags out properly
