php - Improving simple order query -

-

मैंने इस तरह mysql क्वेरी बनाई: 

  का चयन करें m_id, user, date, home, दूर, चुनना, हिस्सेदारी, अजीब, एनालिजा, रेजल्टैट, खेल, मैच के समय का समय है, जहां दिनांक & gt; DATE_SUB (NOW (), INTERVAL 1 सप्ताह) $ ऑर्डर के अनुसार $ DESC $ सीमा   
 आप देख सकते हैं यह ऑर्डर $ आदेश है  
 पृष्ठ के शीर्ष पर मैं हूं $ आदेश की खोज इस तरह से  
  अगर (isset ($ _ GET ['order'])) {$ order = $ _GET ['order']; } और {$ order = "date"; }   
 मैं यह कैसे कर सकता हूँ कि यूआरएल में उपयोगकर्ता इनपुट कहता है कि: index.php? चूंकि केवल दो संभावित विकल्प दिनांक और दिनांक के अनुसार क्रमबद्ध हैं  
 धन्यवाद   
 
 
 स्विच / केस का उपयोग करें।  
  <पूर्व>  स्विच ($ _ GET ['ऑर्डर']) {केस 'डेट टाइम': $ order = 'datetime'; टूटना; डिफ़ॉल्ट: $ order = "date"; }

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...
