Memory Issues with PHP (5) -

-

Is calling unset () free from memory related to that object? There are some cases where I feel myself dealing with large associative arrays and want to remove them whenever they are done (freeing memory to make new ones).

< / Strong>

Check yourself by using: 

  echo memory_get_usage (). "& Lt; br / & gt;"; Not set ($ array ['key']); Not set ($ array ['key2']); Not set ($ array ['key3']); Echo memory_get_usage (); Quoted from the link later:         
 
 
 
 
 
 
 
 PHP stores garbage on three primary junctions: 
 
     
  1.  when you leave it 
    2.  Li> when you leave the function  
  2.  When the script ends 
    3.  
 
 Position 1 occurs when you use  unset () , mysql_free_result (), or other resource-deleting functions Clearly clear after your variables, position 2 clearly clear the resources Is - no one gives variable which left scope, that is no longer applicable, your clean. Finally, position 3 vests all script-related resources.

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).
