[PHP] isset doesn't like -?
I don't know if this is a bug, or what, but I get an error when trying the
following
if ( isset($adodbobject-Fields('myresult') ) ) { // do something }
PHP throws an error ( not warning ) saying:
Parse error: parse error, expecting `','' or `')'' in /path/to/index.php on
line 45
However, when I modify the isset to look like this:
$_q = $adodbobject-Fields('myresult');
if ( isset($_q) ) { // do something }
It works fine.
Is this proper behavior for isset, or is this a php bug? I can't search
google groups for -, or any other search engine for that matter. So it
has been tough trying to see if anyone else gets this error.
Many thanks!

PS: what is the proper term for the - syntax? pointer?

That's because isset() is expecting a variable, not a function. In your
first example, you're trying to see if a function is set, not a
variable. In your second example, you're doing it right...

That actually makes sense once I thought about it, a function referencing a variable, or reference to a variable is in no way the same as a variable.

I think in PHP the technical term for it is that - thingy... :-) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
