What is your favorite PHP programming trick? -

What is your preferred PHP programming age?

I like myself 

  function cached function ($ foo) {constant $ result = array} / div>

If the result of the function does not change during the course of your application, you can get a more quick call in the cached function.

A well-designed application will not be needed but without much effort, it is very useful to squeeze a lot of performance from the old or bad engineer system.

I worked on the project where it reduced the time for the average HTTP request, about fifty% Because the app was constantly calling the same function without the need for a "fresh" result.

Just keep in mind: this trick can give you out-to-date data! so be careful.

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).
