You can also print execution information, such as
the current file being executed. The name of the function
currently being executed can be retrieved using the function
get_active_function_name()
. This function returns a pointer to the function name and
doesn't accept any arguments. To retrieve the name of the
file currently being executed, use
zend_get_executed_filename()
. This function accesses the executor globals, which are
passed to it using the
TSRMLS_C
macro. The executor globals are automatically available to
every function that's called directly by Zend (they're part
of the
INTERNAL_FUNCTION_PARAMETERS
described earlier in this chapter). If you want to access the
executor globals in another function that doesn't have them
available automatically, call the macro
TSRMLS_FETCH()
once in that function; this will introduce them to your local
scope.
Finally, the line number currently being
executed can be retrieved using the function
zend_get_executed_lineno()
. This function also requires the executor globals as
arguments. For examples of these functions, see
例36-2
.
