php - How to check if $_GET is empty? -


कैसे जांच करें कि $ _ GET खाली है?

आपने स्वयं कहा था, जांचें कि यह है: 

  यदि (खाली ($ _ GET)) {// no डेटा प्राप्त हो चुका है}

देखें, PHP बहुत सीधा है आप बस लिख सकते हैं, आपको क्या लगता है;)

यह विधि काफी सुरक्षित है यदि $ _ GET अनसेट नहीं किया गया था (संभावित नहीं, लेकिन संभव है) ! $ _ GET आपको एक अपरिभाषित चर E_NOTICE दे सकता है।

But I do not think the code is capable of changing the color of each variable declared....
