=== Code Blocks ===

Blocks of code are called when a specific piece of code signals that it is a representation of a block of code. Variables defined in one code block cannot be applied or changed in other nonrelated code blocks; this is known as scope. For example:

 $myGlobalVariable = getNumber();
 
 while($myGlobalVariable != 0) {
     
    $myLocalVariable = 0;
    $myGlobalVariable = $myLocalVariable;
 }
 
 $myLocalVariable = 50; // this is invalid; myLocalVariable does not exist in this scope

Once the interpreter reads the closing bracket, it destroys all variable definitions within the scope, therefore you cannot use any of the variables that existed in that particular block of code.
