Variables method names for classes

Question

How can I call a function in a class that depends on a user's input.

So if the user sent 2011 I want to call the method $record->show_2011()

if they sent the input 2012 I want to call the method $record->show_2012()

else I want to call $record->show()

How do I pass in the user's input into the method name to call it?

Probably best to map incoming variables to method / function names. — user399666

Can't you just pass it into a function as a param instead? — raina77ow

You need to put the function name in a variable first, e.g. $function_name = 'set'.$request->getFirstProperty(); and then $record->$function_name();

You can also do it this way:

$record->{'show'}(); $record->{'show_' . $variableThatHoldsTheRestOfFunctionName}();
