Add validUndefinedVariableNamesInFileScope #243
Labels
Comments
This is a good idea and I think should be fairly easy to implement. I'll see if I can make the time to do so (although if you have time, feel free to give it a try!) |

Where a variable is available within the File scope, it will not be available within a function scope without the use of
global $varname;
.At the moment it's possible to either set:
validUndefinedVariableNames
, but this will incorrectly apply within function scope where the variable is not available to be used; orallowUndefinedVariablesInFileScope
, but this is an on/off value and may not be accurate.It should be possible to define which variables are allowed to be used within the file scope.
