break; will take you out of the top level control structure, and it seems
that if() statements are not classed as control structures under PHP. When
you do a break <number>; you are breaking out of the top level
control structure and trying to execute a second break; when there is no
loop to break out of. What I usually do is if I am iterating until I find
something useful, I put that in a control structure of it's own and allow
the flow of the program to take me down to the next set of if() or while()
clauses. I tried to write a mad regexp script with tons of nested loops
and I ended up getting lost. ;)

I hope that makes sense.

Cheers,
