PHP Variables Scope?
The previous variables are reassigned new values.
If it is just like you have it listed, then the $name and $gender variable's values are replaced with "ELENA" and "FEMALE" Why don't you try, echo $name;, echo $gender.
As Codeacula said, those variables will be overwritten. The opening and closing PHP tags do not define scope. Variables are in what's called the global scope unless they are inside of a function or class.
Global methods are as the name implies available, and can be overwritten inside functions and classes When a variable is inside of a function then that variable is only available inside of that function unless it is prepended with the keyword global. A quick search on google will give you more information on variable scope.
Sometimes a variable available in global scope is not accessible via the 'global' keyword or the $GLOBALS superglobal array. I have not been able to replicate it in original code, but it occurs when a script is run under PHPUnit. PHPUnit provides a variable "$filename" that reflects the name of the file loaded on its command line.
This is available in global scope, but not in object scope. For example, the following phpUnit script (call it GlobalScope. Print "Method scope GLOBALSFILENAME ".
If you run this script via "phpunit GlobalScope. Global scope FILENAME /home/ktyler/GlobalScope. PHPUnit 3.4.5 by Sebastian Bergmann.
Print "Method scope GLOBALSFILENAME ". By doing this, both "global" and $GLOBALS work! I don't know what it is that PHPUnit does (I know it uses Reflection) that causes a globally available variable to be implicitly unavailable via "global" or $GLOBALS.
But there it is.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
