ठीक है, तो अपने सर्वर से या तो ftp या sftp के माध्यम से अन्य सर्वरों तक पहुंच रहा है ... मैंने या तो संभालने के लिए एक छोटी कक्षा लिखी है .. यह स्पष्ट रूप से नया है और आसानी से सुधार किया जा सकता है इसलिए सोचा कि मैं चाहता हूं इसे यहां फेंक दो और देखें कि अन्य लोग क्या सोचते हैं (स्टैक ओवरफ्लो को बहुत सारे विचारों का नरक मिल जाता है, इसलिए उम्मीद है कि यह किसी और की मदद कर सकता है), और वे इस पर कैसे सुधार कर सकते हैं ... तो मुझे लगता है कि सवाल यह है कि ... कैसे हो सकता है यह सुधार किया जा सकता है?PHP एफ़टीपी/एसएफटीपी स्विच क्लास
