hey, i have a script i want to test my paypal API with and for some reason i got this error:

im not sure if i need to enable soap on my php or what, but this is the error i got:


Fatal error: Class 'SoapClient' not found in C:www scripts phppaypalpro php paypalpro-0.2.1 paypal_base.php on line 401

have you ever seen this?

using:
php5
apache 2
os: windows
UPDATE: i found a way to fix this error, just send this command:
yum install php-curl
then start your server:
/etc/init.d/httpd restart
