#21791 [Opn->Fbk]: problems with reference passing through layers of functions in windows/IIS/sapi

ID: 21791 Updated by: sniper@php.net Reported By: fishrunsrap@hotmail.com -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: windows PHP Version: 4.3.0 New Comment: Please provide a _SHORT_ and _COMPLETE_ example script which can be used to reproduce this. Previous Comments: ------------------------------------------------------------------------ [2003-01-21 00:55:10] fishrunsrap@hotmail.com I upgraded PHP to 4.3.0, from 4.2.3, running in IIS5 as a SAPI module. I had hacked stored procedure support for MSSQL into the PEAR DB class with a function like: function spBindOutputParam($stmt, $name, &$outref, $type) { return mssql_bind($stmt, $name, &$outref, $type, true, false); } ... right? then, in my own DBAbstraction classes, I had something like: function bindOutputParam($name, &$outref, $type) { /// debugger global $debug; //$debug->println("DBStoredProcedure::bindOutputParam() called, outref = ".$outref."", 5); return $this->db_connection->spBindOutputParam($this->db_stmt, $name, &$outref, $type); } ... and so on, up through the layers of abstraction in my application framework, always passing the output parameter $outref by value. I upgraded to PHP 4.3.0 and it BROKE. the functions all completely failed to modify $outref. it works fine, I stress, in PHP 4.2.3. I desperately tried a bunch of stuff like removing the '&' from ONLY the function signatures, or ONLY the subsequent calls, or what have you. totally busted. has anyone run into anything like this? I'm guessing it's a PHP 4.2.3->4.3.0 thing but who knows? maybe also with MSSQL in PHP. let me know. thanks! -fish ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21791&edit=1
