php - How to use an object method as a callback function -

-

मेरे पास एक सिंगलटन कक्षा में नीचे विधि है 

  निजी फ़ंक्शन एन्कोड ($ inp) {If_array ($ inp) {return_array_map ('$ this- & gt; एन्कोड', $ inp);} और अगर is_scalar ($ inp) {return str_replace ('% 7E', कच्चेरलेनकोड ($ inp));}

यह सामान्य कार्य के रूप में ठीक काम करता है 

  फ़ंक्शन एन्कोड ($ inp) {if (is_array ($ inp) रिटर्न सर_मैप ('एन्कोड', $ INP);} और अगर is_scalar ($ INP) {वापसी स्ट्र_रेले ('% 7E', कच्चेरलेनकोड ($ inp));} else {return ''}}}  < / Pre> 
 जब मैं एक वर्ग के अंदर का उपयोग कर रहा हूं तो मुझे नीचे त्रुटि मिलती है: 
 
 
 PHP चेतावनी: array_map (): पहला तर्क, '$ this-> rfc_encode', होना चाहिए या तो शून्य या एक वैध कॉलबैक 
 
 
 कृपया मुझे इसे ठीक करने में कोई मदद कर सकता है।

से:

एक तत्काल वस्तु की एक विधि ऑरेक्स के रूप में पारित की जाती है जिसमें इंडेक्स 0 पर एक ऑब्जेक्ट होता है और सूचकांक 1 पर विधि का नाम होता है।

तो कोशिश करें 

  वापस सरणी_मैप (ऐरे ($ $, 'एन्कोड'), $ INP);

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
