arrays - PHP: Trim every element in an object and if empty, set to N/A -


मेरे पास एक ऑब्जेक्ट है: 

  stdClass ऑब्जेक्ट ([रंग] = & gt; लाल [ आकृति] = & gt; गोल [स्वाद] = & gt; मीठा)

मैं ऑब्जेक्ट में से प्रत्येक तत्व को ट्रिम करना चाहता हूं और यदि वह तत्व खाली है, तो इसे 'एन / ए' पर सेट करें '

तो इस ऑब्जेक्ट: 

  stdClass ऑब्जेक्ट ([रंग] = & gt; लाल [आकार] = & gt; [स्वाद] = & gt; मीठा)

यह हो जाएगा: 

  stdClass ऑब्जेक्ट ([रंग] = & gt; लाल [आकार] = & gt; एन / ए [स्वाद] = & gt; मीठा)   
 मुझे इसे कैसे पूरा करना चाहिए, array_walk हो सकता है?   
 
 
 इसे रखिए सरल:  <पूर्व>  $ foo = नया स्टड क्लास; $ Foo- & gt; prop1 = 'foo'; $ Foo- & gt; prop2 = NULL; $ Foo- & gt; prop3 = 'बार'; विदेशी मुद्रा ($ foo के रूप में & amp; $ prop) {$ prop = trim ($ prop); अगर (खाली ($ प्रोपे)) {$ prop = 'N / A'; }} Print_r ($ foo);

और ऐसा होगा: 

  stdClass ऑब्जेक्ट ([prop1] = & gt; foo [prop2] = & gt; एन / ए [प्रोप 3] = & gt ; बार)

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
