PERL Caller equivalent function

[sgsweb <sgsweb@xxxxxxxxxxxxxx>]

Hi,

Perl has a function named caller with the following signature and return 
values:

   ($package, $filename, $line, $subroutine,
    $hasargs, $wantarray, $evaltext, $is_require) = caller($i);

This function returns information pertaining to the calling routine, 
such as the name of the function and package that called this function.  
Is there such a function for PHP?

Please let me know.

thanks,
sgs.
