loops - 'if' inside 'while' statement in php -

-

I have this code that has a thinness through an array and removes the result on the page:

while ($ row = mysqli_fetch_array ($ result)) {resonant '& lt; Tr & gt; & Lt; Td> & Lt; A target = "_ blank" href = "'. $ Line [' url '].' '& Gt;'. $ Line ['name'] '& lt; / a & gt; & lt; / td & gt; ; ' . '& Lt; td & gt; . $ Line ['provider'] '& lt; / td & gt;' . '& Lt; td & gt; $ Line ['media'] "& lt; / Td> & Lt; / Tr & gt; & Lt; Br / & gt; \ N ";}

It just works fine, but I was hoping to use the 'if' statement on line $ ['media'] because some tap in it and There are some! Null results.

I want to resize a small reaction like this:

If ($ line ['media'] = null) {echo 'no'; } And {echo $ line ['media'];}

Is this possible in this situation?

Thanks.

Use: 

  if (is_null ($ line ['m Ia '])) {...} else {...}

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).
