I suspect that this is where my error is. But I have added another fprintf to the mod_php4.c file that prints a message when entering the php_init_handler function and when it exits. The php_init_handler function is registered as the module_init callback which I believe is what Apache calls when initializing the module.
Amazingly, it prints this: (I added the parentheses below to identify the src file) mod_php4.c: php_init_handler: starting to run (zend_ini_scanner.l) lex returning 'startofphpini' (zend_ini_scanner.l) lex returning 'hereami' (zend_ini_parser.y) 'startofphpini' = 'hereami' (zend_ini_scanner.l) lex returning 'engine' (zend_ini_parser.y) 'engine' = '1' (zend_ini_scanner.l) lex returning 'short_open_tag' (zend_ini_parser.y) 'short_open_tag' = '1' (zend_ini_scanner.l) lex returning 'asp_tags' (zend_ini_parser.y) 'asp_tags' = '' .. snipped .. mod_php4.c: php_init_handler: all completed mod_php4.c: php_init_handler: all completed Apache/1.3.23 (Win32) PHP/4.3.0-dev running... (zend_ini_parser.y) 'startofphpini' = 'hereami' (zend_ini_parser.y) 'engine' = '1' (zend_ini_parser.y) 'short_open_tag' = '1' (zend_ini_parser.y) 'asp_tags' = '' .. snipped .. At the initial step, it is clear that the ini parser is called by php_init_handler. But why is the same "php_ini_handler: starting to run" not printed the second time? And, why does the parser no longer call the lexer? I am sure that you are correct, Rasmus, and apache is calling it twice, but what I don't understand is, why are the messages not identical? dave -----Original Message----- From: Rasmus Lerdorf [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 19, 2002 5:21 PM To: David Viner Cc: Php-Dev@lists. php. net Subject: RE: [PHP-DEV] ini question Apache calls the module startup hook twice.
