When using cURL with PHP, you can automate a lot of operations easily.- Basic cURL:
PHP Code:
$ch = curl_init('http://www.target.com'); // the target
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // return the page
$result = curl_exec($ch); // executing the cURL
curl_close($ch); // Closing connection
echo $result;
- Post via cURL:
PHP Code:
$data = 'field_name=field_value&submit_value=submit';
$ch = curl_init('http://www.target.com'); // the target
curl_setopt($ch, CURLOPT_POST, 1); // telling cURl to POST
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch); // executing the cURL
curl_close($ch); // Closing connection
- Using cookies with cURL:
( You will find this useful when you are trying to do something that needs a login and a cookie stored )
PHP Code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.target.com');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, '/path/to/cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, '/path/to/cookie.txt');
$result = curl_exec($ch);
curl_close($ch);
echo $result;
- Extra info:
You can set `user-agent`, `referrer`, `headers`.. using cURL:
PHP Code:
// set user-agent to DarkMindZ
curl_setopt($ch, CURLOPT_USERAGENT, 'DarkMindZ');
PHP Code:
// set referrer darkmindz.com
curl_setopt($ch, CURLOPT_REFERER, 'http://www.darkmindz.com');
This function will help you a lot in making things go easy:
PHP Code:
function curl_it($method, $target, $post_var)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $target);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, '/path/to/cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, '/path/to/cookie.txt');
if ($method == 'POST') {
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_var);
}
$result = curl_exec($ch);
curl_close($ch);
}
// usage:
curl_it('', 'http://www.darkmindz.com'); // get darkmindz.com homepage
curl_it('POST', 'http://www.darkmindz.com', 'user=dude&pass=dude2'); // login using dude:dude2
