PHP- HTML parsing :: How can be taken charset value of webpage with simple html dom parser? -

-

PHP :: कैसे सरल (यूटीएफ -8, विंडोज़-255, आदि।) के साथ वेब पेज का अक्षरसेट मान लिया जा सकता है

टिप्पणी: इसे html dom पार्सर के साथ किया जाना है

उदाहरण 1 वेबपृष्ठ वर्णसेट इनपुट: 

  & lt; मेटा सामग्री = "पाठ / html; वर्णसेट = यूटीएफ -8" http-equiv = "सामग्री-प्रकार" & gt;

परिणाम: यूटीएफ -8

उदाहरण 2 वेबपृष्ठ वर्णसेट इनपुट: 

  & lt; मेटा सामग्री = "टेक्स्ट / html; charset = windows-255" http-equiv = "सामग्री-प्रकार" & gt;

परिणाम: खिड़कियां -255

संपादित करें:

मैं यह कोशिश करता हूँ (लेकिन इसका काम नहीं करता ): 

  $ html = file_get_html ('http://www.google.com/'); $ एल = $ html- & gt; लगता है ( 'मेटा [सामग्री]', 0); गूंज $ el- & gt; वर्णसेट;

क्या बदलाव होना चाहिए? (मुझे पता है कि $ एएल-> वर्णसेट काम नहीं कर रहा है)

धन्यवाद

आप 'स्ट्रिंग को नियमित अभिव्यक्ति का उपयोग करना होगा (मुझे आशा है कि आपके पास पीसीआर है ...)। 

  $ el = $ html- & gt; खोजें (' मेटा [http-equiv = content -टाइप] ', 0) $ fullvalue = $ el- & gt; सामग्री; Preg_match ('/ charset = (। +) /', $ पूर्णवल्यू, $ मैचों); प्रति मैच गूंज [1];

बहुत मजबूत नहीं है, लेकिन काम करना चाहिए।

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).
