Academic curiosity -
You can do the following:
echo "3 - 2 = " . ( bcsub( 3, 2 ));
and PHP evaluates the expression in parenthesis (in this
case a function) before it evaluates the echo statement
and what gets printed out is:
3 - 2 = 1
Now, say I have a function where one of the arguments
is passed by reference and is modified within the function.
I can call this function on one line
myFunc( &$modifiedVariable );
and print out the value (if any) of $modifiedVariable on
the next
echo $modifiedVariable.
So what I am wondering is if you can turn those two
statements into one? The function is going to get evaluated
first we already know, but I am not certain how I could
get the (new) value of $modifiedVariable. Yes, it's just one
extra line but that is not why I ask. I was thinking about it
yesterday and I became very curious if it could even be done.
Nothing I tried yielded results so I'm turning to the experts.
:p
Is this possible?
Thanks for entertaining my curiosity!
