This will help you.

class spider
  {
    // This class grabs the content from the sites				
  	function setup()
  	{
  		$cookieJar = 'cookies.txt';			
  		curl_setopt($this->curl,CURLOPT_COOKIEJAR, $cookieJar); 
  		curl_setopt($this->curl,CURLOPT_COOKIEFILE, $cookieJar);
  		curl_setopt($this->curl,CURLOPT_AUTOREFERER,true);
  		curl_setopt($this->curl,CURLOPT_TIMEOUT,30);
  		curl_setopt($this->curl,CURLOPT_CONNECTTIMEOUT,25);
  		curl_setopt($this->curl,CURLOPT_FOLLOWLOCATION,true);
  		curl_setopt($this->curl,CURLOPT_RETURNTRANSFER, true);		
  	}
  	
  	function get($url)
  	{ 
  		$this->curl = curl_init($url);
  		$this->setup();			
  		return $this->request();
  	}
  	
  	function request()
  	{
  		return curl_exec($this->curl);
  	}
  }

Ive used http://www.sphider.eu/ and found it pretty good. It is open source too so you have the code to work with and see how he did it.

 

Awesome! Thanks everyone.
