Bug description: magic constant __CALLED_FROM__
Description:
------------
Please add a new magic constant like __FUNCTION__ only it
displays what function the current function was called
from. This would be good for debugging, and an error
handleling function.
Reproduce code:
---------------
// I know die could do it. This is just an example
function error($error) {
echo "There was an error in '".__CALLED_FROM__." '$error";
}
function normal($arg) {
// For debuging:
echo __FUNCTION__.'called from:'.__CALLED_FROM__."\n";
echo $arg;
}
function call_normal() {
normal("Some Text\n");
}
function call_normal_again() {
normal("Other Text\n");
}
normal("hi\n";);
call_normal();
call_normal_again();
error("No Error\n");
Expected result:
----------------
normal called from:
hi
normal called from:call_normal
Some Text
normal called from:call_normal_again
Other Text
There was an error in '' No Error
My examples are pretty basic, but I can see where a magic
constant like __CALLED_FROM__ could be very useful.
You could use it to make sure that the data that a function
is getting fed is the right data, and if there's an error
report what function did the call. So then you can fix it
faster, and more efficiently.
Thanks ahead of time for adding it, and if not thanks for
your time.
Actual result:
