I'm using:
ZEND_DLEXPORT zend_extension zend_extension_entry = {
XDEBUG_NAME,
XDEBUG_VERSION,
XDEBUG_AUTHOR,
XDEBUG_URL,
"Copyright (c) 2002, 2003, 2004",
xdebug_zend_startup,
xdebug_zend_shutdown,
NULL, /* activate_func_t */
NULL, /* deactivate_func_t */
NULL, /* message_handler_func_t */
NULL, /* op_array_handler_func_t */
xdebug_statement_call, /* statement_handler_func_t */
NULL, /* fcall_begin_handler_func_t */
NULL, /* fcall_end_handler_func_t */
NULL, /* op_array_ctor_func_t */
NULL, /* op_array_dtor_func_t */
STANDARD_ZEND_EXTENSION_PROPERTIES
};
I really need the statement call callback for single stepping through
code.
