I tend to avoid += since it's a "magic" edge case in variable scope.
If all of my code takes the strict view that variables are immutable, I
am much less likely to confuse anyone who reads my code later.
Just to be clear, the += does *not* mutate, it creates a new variable
that shadows the original in an outer scope.
This does end up with stupid code like $l_var = $var + ['foo'], but that
can't be helped while preserving clarity.
Now, I would LOVE the ability to manipulate all variables within scope.
That would be very nice and then I would vote for keeping += around.
That would allow for things like:
if empty($foo) {
$foo = 'bar'
}
Instead of:
if empty($foo) {
$l_foo = 'bar'
}
else {
$l_foo = $foo
}
Which is irritating.
