Can Philippines send money through PayPal?

Now you can send local or international payments from anywhere you happen to be, at home or on the go. All you need is the recipient's email address. If they're new to PayPal, they can create an account quickly for free.

I was looking for the same issue, here's what is working for me. Tested in 'sandbox' mode and using NVP (instead of SOAP). Your server must support CURL, in order to verify it use:

<?php
echo 'curl extension/module loaded/installed: ';
echo ( !extension_loaded('curl')) ? 'no' : 'yes';
echo "<br />\n";
phpinfo(INFO_MODULES); // just to be sure
?>

If is not loaded or installed ask to your hostmaster or get it here, otherwise go ahead:

<?php
// code modified from source: https://cms.paypal.com/cms_content/US/en_US/files/developer/nvp_MassPay_php.txt
// documentation: https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/howto_api_masspay
// sample code: https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_code

// eMail subject to receivers
$vEmailSubject = 'PayPal payment';

/** MassPay NVP example.
 *
 *  Pay one or more recipients. 
*/

// For testing environment: use 'sandbox' option. Otherwise, use 'live'.
// Go to www.x.com (PayPal Integration center) for more information.
$environment = 'sandbox'; // or 'beta-sandbox' or 'live'.

/**

 *
 * @param string The API method name
 * @param string The POST Message fields in &name=value pair format
 * @return array Parsed HTTP Response body
 */
function PPHttpPost($methodName_, $nvpStr_)
{
 global $environment;

 // Set up your API credentials, PayPal end point, and API version.
 // How to obtain API credentials:

 // Set the API operation, version, and API signature in the request.

Good luck!
