| actually, tony, j.aho's reply was the most accurately concise description
of
| scope that i've seen. also, "return" is ENTIRELY in the realm of
discussion
| of scope! what's the difference between returning a copy of a value versus
a
| pointer to where a value resides? SCOPE.
|
| don't get caught up on the op's use of the word "global". it has little to

using
| globals are a bad idea. what's the difference in a public, static variable
| of a class and a global variable? SYNTAX. (and the version of php you're
| using ;^)
|
| had you read the op's question thouroughly, you wouldn't "expect that you
| [he] simply haven't [hasn't] declaired [sic] variables as being global
when
| you [he] should have". this only shows you didn't look at his code at
| all...or didn't understand it at all. his function example takes a
parameter
| in lieu of using global...which is good. in his example, the parameter is
| $_POST. you also failed to notice that he is not changing a local copy of
a
| global variable...the op is RETURNING a value from within the $_POST array
| via his function.
|
| either take time to read the op's problem, question, and code, or don't
| bother posting a reply.
DAMN FUCKING OE !!! perhaps you did read the correct thread afterall! i saw
your post show up under another tread that is similar in topic. anyway...ALL
applies except the last two paragraphs even still. ;^)
