PayPal是用戶成功地返回到與正確的GET變量頁：

?status=success&tx=203229VT863344T&st=Pending&amt=76.00&cc=GBP&cm=19&item_number=

但是當腳本運行時，它返回「error2」。當我嘗試輸出迴應時，我什麼也得不到。

感謝您的幫助。

不應該的fsockopen是指定SSL：//sandbox.paypal.com？你還沒有提到ssl協議。還有哪裏會出現「error2」？你的代碼片段沒有「error2」。 – while1

你應該張貼回：
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);

而不是：
$fp = fsockopen ('www.sandbox.paypal.com', 80, $errno, $errstr, 30);
