Bug #17343: Resource encapsulation can break some functions

From: chris@thumbtack.org Operating system: Linux PHP version: 4.2.1 PHP Bug Type: Unknown/Other Function Bug description: Resource encapsulation can break some functions When using mysql_insert_id() if you've made a call using a wrapped function (ie, my_database_query($query) wrapping mysql_query()) the database resource may not be "set" to allow using the last connection. Ex. 1) Call my_database_connect() and store the returned mysql Link as $res. Note that it's a copy... 2) call my_database_query($query, $res) and insert something with an auto_increment field. 3) call mysql_insert_id() and it'll fail. 4) call mysql_insert_id($res) and it'll work. It appears that mysql_insert_id() looks for the last used connection, but if that connection resource is "wrapped/copied" then the ZEND_GET_RESOURCE-type method can't find it. Storing a REFERENCE to the mysql link in (1) will allow proper usage, but storing a copy does not. This was exposed using mysql, but it may have deeper meaning to other modules - hence the "Unknown/Other Function" category chris@thumbtack.org -- Edit bug report at http://bugs.php.net/?id=17343&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17343&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17343&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17343&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17343&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17343&r=support Expected behavior: http://bugs.php.net/fix.php?id=17343&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17343&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17343&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17343&r=globals
