Re: BC break: $o= new stdclass; empty($o)

Hey, The reason for this behavior is that in PHP 3 and 4, objects were treated very much like arrays (this is the main reason for redesigning the object model for PHP 5). I don't think that the old behavior is correct and an empty should always return true (i.e. empty($var) should return true if the variable is NULL and false if $var is an object). I don't think we should by default support the PHP 4 behavior because it's just not right. What I suggest is to either break BC completely or support the old behavior in compatibility mode. What option do you prefer? Andi At 07:03 PM 2/29/2004 +0100, Timm Friebe wrote:

I have a patch, but that includes a TSRMLS_FETCH() - maybe it would be wise to change: ZEND_API int zend_is_true(zval *op); to ZEND_API int zend_is_true(zval *op TSRMLS_DC); but that breaks the API. - Timm -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
