I have found a command line script that runs an array () one of the files Using a filename as an argument to call a method on loop, and a helper object.

  PHP fatal error: allowing end memory size of 134217728 bytes  < / Pre> 
 It is clear that some memory is leaking, or keeps adding to some type of global / stable storage area. What is the best way to debug this type of error in PHP? Are there normal situations where it is inadvertently PHP? Does Xdebug have some magic options that can help me recognize this? Other equipment? 
 
 The best I'm running, I'm following a series of performance and by calling the codebase to memory_get_usage (), as long as I do not solve the exact problem, but it is a tedious and inefficient Looks like the approach.

It seems that provides Facebook.

(I've never used it, but to really want to ...)

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).
