So far "filled", "varset", "coallesce", "ifsetor" or any operator would likely have to manipulate opcodes. http://php.net/~helly/ze2-ifsetor-20040901.diff.txt From what I understand, zeev and andi are strongly opposed to adding a new opcode. I'm sure they have their reasons. Maybe there's another approach where ~ E_NONE could be passed to zend_error ZEND_API void zend_error(int type, const char *format, ...) /* {{{ */ { if(type & E_NONE) return; } Then modify to zend_vm_gen.php to pass E_NONE if within 'ifsetor'. Either way, there's a solution for it, I think the debate is over how it's implemented. -- Worth reading https://wiki.php.net/rfc/ifsetor#rejected_features -- Why? I think it simply boils down to this: - PHP *developers* want a function for it. Derick
