Someone reported a problem with passing nodes by reference in PHP5. http://drupal.org/node/84430 Here is the text: hanoii - September 15, 2006 - 17:52 I was using drupal 4.7 with PHP5 with any strange behaviour until I found one. If there is a node that is loaded twice, for example if it's shown on the node default homepage and on some block, the links were added twice. Then for instance add new comment and the counter of the statics module were shown twice in the second loaded node. If its loaded three times, then the links are three times. Trying to figure out what was happening I saw that the node was cached inside a static array, but I didn't understand why the cached node that was returned by node_load the second time was the one already modified and after some reading and testing I got to the fact that objects are passed by reference on PHP5. So, node_view($node) is actually passing a reference of the cached node (not a copy as on php4). I am sure you must be aware of this, but I wanted to ask you if you are taking this into consideration for further releases or just stick to PHP4 for now? Shall I submit this as an issue too? I would thing that there may be simillar things going on inside the code as objects are passed everywhere within the core and modules. So my plan right now is to go back to PHP4. Hope this helps, Great work! a.=
