Trying to register a constant value for a class and it keeps crashing. Learning C as I go, so I would appreciate some insight. I can figure out that my *property value is lost during zend_hash_add() but my knowledge stops there as to why. Tried passing property as property and &property. ZEND_METHOD(zboolean, __construct) { zval *object = getThis(); zval *property ALLOC_ZVAL(property); INIT_PZVAL(property); ZVAL_STRING(property, "true", 1); zend_hash_add(&(Z_OBJCE_P(object))->constants_table, "TrueString", sizeof("TrueString")+1, property, sizeof(zval *)); } Thanks Bob

zend_hash_add(&(Z_OBJECE_P(object))->constants_table, "TrueString", sizeof("TrueString"), &property, sizeof(zval *), NULL); should work. - Andrei

The key being that sizeof("Foo") == strlen("Foo") + 1 George

Is there a reason there is no macro for this? (took me a while to figure it out as well) And should it be done in PHP_MINIT_FUNCTION(), rather than __construct Regards Alan George Schlossnagle wrote:

Agree, it would be nice to have a zend_declare_constant function. Yea, I moved it to MINIT for the module afterwards (thinking that may the problem). Been tracing it in VS for many hours now, and essentially it still crashes when it goes to destroy the hash at shutdown. Somewhere between declaring the constant in the constants_table (which works, <?= Zboolean::TrueString; ?> prints "true" But by the time it gets to zend_hash_destroy in destroy_zend_class (running in ZTS mode) the zval in the constants_table is missing. At this point, I'm pretty sure its not me :) I am going to compile my classes under linux and see if it crashes, I'm thinking it wont. I'll spend a few more hours tracing the code and try to find out whats up. Thanks for the help and ideas.
