If you run the following script and check the output, you will see the
that variable JUNK has been dynamically defined in the class X_Row() by
using the statement:
$user->query_row->JUNK = "stuff";
This behaviour certainly wasn't what I would expect.

query_row = new X_Row();

return;
} //end function X_Row
} //X_Row
$user = new X();
//$user->query_row is of class X_Row
//Therefore, the next statement should be valid,
//USERNAME has been declared in X_Row
$user->query_row->USERNAME = 'mtl';

Can someone from an authority standpoint look into this?
If it is a feature, then it is potentially quite dangerous,
both from a security standpoint as well as from on
operational standpoint.
Why bother having class variables at all if that is the
case?

This is a "feature", not a bug. I can see good uses for this, my
DataObject class uses this feature for dynamically adding instance
variables from database records.

Script was already included.
Just cut and paste the PHP code into a text editor and save.
Then run.
The script will cycle through and array, building objects out of the
array. It dumps the values of the objects at certain steps. You will
see the difference if you follow the instructions below.
Run Script once and look at output. You will notice that the dump of
the B class will contain repeat elements (actually, it seems to contain
only the last element of the array that was visited).
Edit Script, deleting the & symbol where I have placed a comment
(***NOTE).
Run Script and look at output. You will see the output is as you would
expect.
Thanks. If you need more info, you can go to my website

I don't want to sound rude, but just run the script as is and you will
see the problem.
This is about as short as I want to get the script so that you see the
problem in depth.
It will take you no amount of time to cut and paste the section into a
new doc and run it. The difference in output will be self explanatory.
So if you would,.just run the script provided.

#21418 [NEW]: Changing PEAR::DB
From: [EMAIL PROTECTED] Operating system: PHP version: 4.2.3 PHP Bug Type: Feature/Change Request Bug description: Changing PEAR::DB I am justing getting into working with the PEAR::DB and DB_DataObjects code. I have some changes that I am making to PEAR::DB and would like to know who to talk to or how I should submit those changes. The following is what I am changing: In PEAR::DB common.php file: Added an new option to the $options array: 'setPrefetch' => 1 For advanced Oracle queries, you use the OCI8setPrefetch limit to > 1. Other databases might find this useful for processing large queries if supported by the database type. Secondly, in PEAR::DB DB.php I am adding a fetchStatement routine to DB_result class that supports limiting and the rownum feature. This then calls the appropriate $this->dbh->fetchStatement() routine. There are others as well, adding a static variable to numCols and numRows so that fetchStatement can load these variables, while fetchInto and fetchRow stills functions as expected. In DB_oci8, changed constructor to use OCI8setPrefetch based upon the $this->option["setPrefetch"] Created an OCI8setPrefetch function so that it can be called specifically/dynamically when the option changes. Currently the change only is reflected in new DB objects after setOptions is called. As mentioned, changed numRows/numCols also in DB_oci8. Adding DB_AUTOQUERY_DELETE to buildManipSQL. Other changes, I am adding. Get number of rows for table in tableInfo for oci8. Can use statistics from the table or use COUNT(*) - I will be doing this shortly. I am doing a very large project with PEAR::DB and DB_DataObjects using Oracle to start, with versions running on mysql, mssql, potentially access, db2, Sybase, etc. In doing so, I have created an offshoot of DB_Dataobjects that will fully sustain many Databases in the same fashion as PEAR::DB. Alan and I have already talked about it. But I am just informing the community. How can I submit the changes to the PEAR::DB code. -- Edit bug report at http://bugs.php.net/?id=21418&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=21418&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=21418&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=21418&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=21418&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=21418&r=oldversion Not developer issue:http://bugs.php.net/fix.php?id=21418&r=support Expected behavior: http://bugs.php.net/fix.php?id=21418&r=notwrong Not enough info:http://bugs.php.net/fix.php?id=21418&r=notenoughinfo Submitted twice:http://bugs.php.net/fix.php?id=21418&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=21418&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=21418&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=21418&r=dst IIS Stability: http://bugs.php.net/fix.php?id=21418&r=isapi Install GNU Sed:http://bugs.php.net/fix.php?id=21418&r=gnused
