ini_set("zend_test.observer.observe_function_names", "bar");

Why is

php-src/ext/zend_test/observer.c

Line 349 in 79c71c9

STD_PHP_INI_ENTRY("zend_test.observer.observe_function_names", "", PHP_INI_ALL, zend_test_observer_OnUpdateCommaList, observer_observe_function_names, zend_zend_test_globals, zend_test_globals)

PHP_INI_ALL?
