  <title>Basic curl example</title>

   Once you've compiled PHP with cURL support, you can begin using
   the cURL functions. The basic idea behind the cURL functions is
   that you initialize a cURL session using the
   <function>curl_init</function>, then you can set all your
   options for the transfer via the <function>curl_setopt</function>,
   then you can execute the session with the 
   <function>curl_exec</function> and then you finish off 
   your session using the <function>curl_close</function>. 
   Here is an example that uses the cURL functions to fetch the 
   example.com homepage into a file:
   <example>
    <title>Using PHP's cURL module to fetch the example.com homepage</title>
    <programlisting role="php">
<![CDATA[
<?php

$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
if(curl_error($ch)) {
    fwrite($fp, curl_error($ch));
}
curl_close($ch);
fclose($fp);
?>
