PHP5 bloats the code

Hi there, i don´t know if this is the right place to ask but since there are a lot of cracks around i thought i throw this in here. actually i am using typo3 (www.typo3.org) a full-blown, extendable cm-framework that is based on php. so here is the problem: typo3 very often uses a syntax like this: is_array($TCA['pages']['columns']['title']) but this will spawn an error in PHP5 that says, "$TCA['pages']" is not an array. The solution would be if ( is_array($TCA['pages']) && is_array($TCA['pages']['columns']) && is_array($TCA['pages']['columns']['title']) ) actually that is really ugly code and would be hardly acceptable. i dunno who to ask, but if that is a verified issue and this behaviour goes in the final php5 we had a lot of trouble - so who can i ask to make it work "the old fashioned" way as well? - Johannes
