php - How do I do this query with ActiveRecord Class from Code Igniter? -

-

I need to increase the number of comments on the entries table, for this would be SQL: 

  Enter entries to entries Comments = Comments + 1 WHERE entry_id = 123;

And I was wondering how to use the active code class form code ignition.

Your question is too much a duplicate of the third parameter of the set on FALSE Setting prevents you from avoiding data. 

  $ this-> Db- & gt; Set ('Comments', 'Comments + 1', Wrong) $ - & gt; DB- & gt; Where ('entry_id', 123); $ This- & gt; Db- & gt; Updates ('entries');

You do not have to stop anything executing SQL if you have an active record slightly peak. 

  $ sql = 'UPDATE entries SET comments = comments +1 WHERE entry_id =? '; $ This- & gt; Db- & gt; Query ($ sql, array (123));

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).
