LIKE SUPERGLOBALS AND PERSISTENT CONSTANTS, which you saw in the last chapter, php.ini values must be declared within an extensions MINIT code block. Unlike these other features however, the INI option declaration consists of nothing more than one simple line for startup, and another for shutdown:
PHP_MINIT_FUNCTION(sample4) { REGISTER_INI_ENTRIES(); return SUCCESS; } PHP_MSHUTDOWN_FUNCTION(sample4) { UNREGISTER_INI_ENTRIES(); return SUCCESS; }
