ZEND_FILE_LINE_D

Used to request the file name and line number of the file being parsed in a function definition

Generally you will use this with ZEND_FILE_LINE_C, ZEND_FILE_LINE_CC, ZEND_FILE_LINE_EMPTY_C, or ZEND_FILE_LINE_EMPTY_CC which are used to pass this info to a function

This is esentially the same as ZEND_FILE_LINE_DC without the built-in preceding comma

If ZEND_DEBUG is not defined, this macro does nothing

This is an alias for char *__zend_filename, uint __zend_lineno
