[thelist] PHP Doubling up

[Luther, Ron]

Hi Andrew,

[I'm not Rich ... but I might have played him on tv.]

Yeah - that's what he's saying.

Rob's post explains that the "+=" operator appends the value from the
right rather than assigns it.

So,

"total = total + new_value"

would be okay or

"total += new_value "

would be okay.

But the "total += total + new_value" is actually equivalent to

"total = total + total + new_value"

which is where the "doubling up" comes in and is probably not what you want.


HTH,


RonL.
