PHP - Method For Sorting Array By Nested Arrays Value -


इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 7 जवाब

    मेरे पास एक php फ़ंक्शन है जैसे कि श्रेणी डेटा के साथ एक सरणी बनाता है: 

      $ categories = array (); विदेशी मुद्रा ($ catIds $ catId) {$ category = Mage :: getModel ('कैटलॉग / श्रेणी') - & gt; लोड ($ catId); $ श्रेणियां [$ वर्ग- & gt; getName ()] = सरणी ('url' = & gt; $ श्रेणी- & gt; getUrl (), 'आईएमजी' = & gt; $ category- & gt; getImageUrl (), 'अंगूठे' = & gt ; संभोग :: getBaseUrl ('मीडिया')। 'सूची'। डी एस 'श्रेणी'। डी एस $ श्रेणी- gtTThumbnail (), 'स्थिति' = & gt; $ category- & gt; getPosition ()); }   
     मैं 'स्थिति' मान से $ श्रेणियों की सरणी को सॉर्ट करना चाहता हूं। मैंने ksort और array_multisort के कुछ भिन्नरूपों की कोशिश की है लेकिन समाधान खोजने में असमर्थ हैं।   
     
     
     ए???? उपयोगकर्ता परिभाषित तुलना फ़ंक्शन का उपयोग करके मानों के आधार पर एक सरणी को व्यवस्थित करें  
      usort ($ श्रेणियां, फ़ंक्शन ($ a, $ b) {$ a = $ a ['position']; $ b = $ B ['स्थिति']; यदि ($ a == $ b) {वापसी 0;} वापसी ($ a & lt; $ b)? -1: 1;});   
     यह मान रहा है कि स्थिति एक संख्यात्मक मान है और आप आरोही क्रमबद्ध हैं।

I have a big code, for a game I'm calling Tommy's Kumamak. I know that this is not beautiful, but I am very naive and for some reasons I know from using arrays, anyway, my problem is that I can not add a variable outside the listener and within the action listener I can modify the variable (pTurn ++) from How can I go about adding a count to that variable from inside the action listener? 1 error was found: file: c: \ user \ public \ togiz_kumalak.java [line: 130] error: local variables pTurn is accessed from within internal class; Need to be declared final int pTurn = 0; Button1.addActionListener {new zero-action action (action event e) {pTurn ++; if (pTurn% 2 == 0) {display.append ("\ n Player 2 cup 1");} If ( PTurn% 2! = 0) {display.append ("\ nPlayer 1Cup 1")}}); In that case, move the contents of the functionalities into orbit and then call the action For example, display the method from: Private Zero Button Press {pTurn ++; If (pTurn% 2...
