ID: 52393 User updated by: r dot spliet at student dot tudelft dot nl Reported by: r dot spliet at student dot tudelft dot nl Summary: __destructor of parameter object called on return -Status: Feedback +Status: Closed Type: Bug Package: Class/Object related Operating System: Fedora 13 PHP Version: 5.3.2 Block user comment: N New Comment: My apologies. My problems were not related to class destruction on itself, but on the behaviour of mysql_connect(). A different object's destructor was (correctly) called, leading to the confusion. debug_print_backtrace() confirmed PHP's behaviour is correct and documented. Previous Comments: ------------------------------------------------------------------------ [2010-07-27 01:05:11] ka...@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2010-07-21 20:23:48] r dot spliet at student dot tudelft dot nl Description: ------------ The situation is as following: class mysqlControl holds a MySQL connection. This class has a __destruct() method to close this connection properly Class x has one of these mysqlControl objects as a private variable. Class y has a method to represent itself in a MySQL way, and needs to escape a string. For this it needs the mysqlControl that class X holds. Now what happens is that Class x calls Class y's method to represent itself in some form that's useful to query MySQL. As a parameter to y's method X gives it's mysqlControl. Before y's method actually starts executing, mysqlControl's destructor is called. This means the connection is closed, and everything breaks. Expected result: ---------------- I expected method y to not call mysqlControl's destructor but just uses the mysqlControl given and forgets about it. Actual result: -------------- mysqlControl's destructor gets called, breaking the mysql_real_escape_string() method before it could be used by class Y's method. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52393&edit=1
