From: ian_c_web at thejolly dot demon dot co dot uk Operating system: NetBSD PHP version: 5.1.2 PHP Bug Type: Scripting Engine problem Bug description: Order of destructor calls seems wrong.
Description: ------------ I have a class that abstracts a database connection, which returns a 'recordset' class for certain operations. The destructor of the recordset class calls the necessary free functions, which were issuing a 'warning: connection closed', which turned out to be related to the database object going out of scope first, and having it's destructor called. So I added a pointer to the database in the recordset, thinking this would keep the database in scope until the recordset was destroyed, but this did not seem to work. If I assigned the recordset to null (hence forcing destruction) everything works as required. I think this is a scoping issue within PHP itself, as it seems to be calling the destructor on the db object too early, although it doesn't seem to actually be destroying the object. (I can still refer to public variables within the object.) Reproduce code: --------------- http://thejolly.demon.co.uk/~ian/phptest.php.txt Expected result: ---------------- SpecificApp construct.
