Save browser output to xml file in php - php

Question

I want to save the below link's output to file.xml but it is not working for me. It just displays the output on another browser.
$url = 'http://www.forexwire.com/feed/full?username=alumfx&password=T7M9Exb4';
$fp = fopen (dirname(__FILE__). '/file.xml', 'w+');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
$ch->save('file.xml');
fclose($fp);

Answer 1

By default CURL's exec function returns the result as standard output. You need to add this to make it return the result as a string:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
then just save it into a variable
$output = curl_exec($ch);
//do whatever with the $output
So that the complete code snippet can look like this:
$ch = curl_init('http://www.forexwire.com/feed/full?username=alumfx&password=T7M9Exb4');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
$output = curl_exec($ch);
curl_close($ch);
file_put_contents('path/to/file', $output);
