PHP's parser gives no importance to whitespace, so yes, these two are 
identical.

In the dual-purpose vision I had for these labels, all labels would be 
usable as GOTO targets.  Labels which are followed *immediately* by a break 
container construct (for, foreach, while, do-while, switch) would also be 
usable as break/continue targets.

Note that in these example, goto LABEL; and continue lABEL; are *not* the 
same statement.  Goto would restart state loops such as for() and foreach() 
from initial positions.
