4. Argument int to size_t in Zend Engine 4.0:
- zend_set_hash_symbol()
u. Instead of overwriting zend_error_cb extensions with debugging, monitoring
use-cases catching Errors/Exceptions are strongly encouraged to use
the new error notification API instead.
Error notification callbacks are guaranteed to be called regardless of
the users error_reporting setting or userland error handler return values.
Register notification callbacks during MINIT of an extension:
void my_error_notify_cb(int type,
const char *error_filename,
uint32_t error_lineno,
zend_string *message) {
}
zend_register_error_notify_callback(my_error_notify_cb);
