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।

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
