PHP - if a value exists in an array of objects -


मेरे पास $ फिलेट नामक ऑब्जेक्ट हैं जो निम्नानुसार हैं: 

  Array ( [0] = & gt; STDClass ऑब्जेक्ट ([शीर्षक] = & gt; प्रकार [उपनाम] = & gt; प्रकार [आईडी] = & gt; 14 [parent_id] = & gt; 9 [subs] = & gt; सरणी ([0] = & gt ; [[शीर्षक] = & gt; कार [उपनाम] = & gt; कार [आईडी] = & gt; 15 [parent_id] = & gt; 14))) [1] = & gt; स्टड क्लास ऑब्जेक्ट ([शीर्षक] = & gt; मॉडल [उर्फ] = & gt; मॉडल [आईडी] = & gt; 18 [पैरेंट_आईड] = & gt; 9 [subs] = & gt; ऐरे ([0] = & gt; स्टडी क्लास ऑब्जेक्ट ([शीर्षक] = & gt; एक्सएफ [उपनाम] = & Gt; xf [आईडी] = & gt; 1 9 [माता-पिता] = & gt; 18) [1] = & gt; स्टडी क्लास ऑब्जेक्ट ([शीर्षक] = & gt; एक्सजे [उपनाम] = & gt; xj [आईडी] = & gt; 20 [parent_id ] = & Gt; 18) [2] = & gt; स्टडी क्लास ऑब्जेक्ट ([शीर्षक] = & gt; एक्सके [उपनाम] => एक्सके [आईडी] = & gt; 21 [माता-पिता] = & gt; 18) [3] = & gt; ([शीर्षक] = & gt; एफ-टाइप [आईडी] = & gt; 22 [parent_id] = & gt; 18))) [2] = & gt; स्टड क्लास ऑब्जेक्ट ([शीर्षक] = & Gt; शर्त [उपनाम] = & gt; शर्त [आईडी] = & gt; 24 [parent_id] = & Gt; 9 [subs] = & gt; ऐरे ([0] = & gt; STDClass ऑब्जेक्ट ([शीर्षक] = & gt; नया [उपनाम] = & gt; नया [आईडी] = & gt; 24 [parent_id] = & gt; 9))))   
 यह जांचने के लिए सबसे अच्छा अभ्यास क्या है कि कोई शब्द $ फिल्टर [$ i] - & gt; शीर्षक और $ फिल्टर [$ i] - & gt; subs [$ j] - & gt; शीर्षक में मौजूद है। स्पीड इस चेकिंग में वास्तव में महत्वपूर्ण है।   
 
 
 एक साधारण रिकर्सिव फ़ंक्शन बनाएँ:  
  फ़ंक्शन myArrayContainsWord (सरणी $ myArray, $ शब्द) {foreach ($ myArray $ तत्व के रूप में) {if ($ element- & gt; title == $ शब्द || (! खाली ($ myArray ['subs']) और ; & Amp; myArrayContainsWord ($ myArray ['subs'], $ शब्द)) {वापसी सच;}} वापसी झूठी;}   
 फिर इसे इस तरह कहते हैं:  
  यदि (myArrayContainsWord ($ filtes, $ title)) {...}

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. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

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...
