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

ID: 21791 User updated by: fishrunsrap@hotmail.com Reported By: fishrunsrap@hotmail.com Status: Open Bug Type: MSSQL related Operating System: windows PHP Version: 4.3.0 New Comment: changed spBindOutputParam to feed mssql_bind() the variable sans ampersand ('$outref', versus '&$outref', as it was) and no go. reference passing still busted. sorry. Previous Comments: ------------------------------------------------------------------------ [2003-01-22 23:51:35] fishrunsrap@hotmail.com ok, I will try this tomorrow in the AM, but I have to ask: what has changed from 4.2.3 to 4.3.0 to make this type of implicit pass-by-reference thing happen? why does it work perfectly normally in 4.2.3? I could find nothing in the changelog that referred to this issue. ------------------------------------------------------------------------ [2003-01-22 22:04:54] sniper@php.net About this: function spBindOutputParam($stmt, $name, &$outref, $type) { return mssql_bind($stmt, $name, &$outref, $type, true, false); } Have you tried adding 'error_reporting(E_ALL);' in the beginning of the script? You propably get some warnings? Try changing the call to: return mssql_bind($stmt,$name,$outref,$type, true,false); ie. don't pass $outref by reference, it's done internally.. ------------------------------------------------------------------------ [2003-01-21 14:54:03] fishrunsrap@hotmail.com under PHP 4.3.0 in IIS5/sapi, the mssql_bind() function does not modify variables passed in for output parameters. ------------------------------------------------------------------------ [2003-01-21 14:52:37] fishrunsrap@hotmail.com the following test script: function inner2(&$val) { $val = "Changed!"; } function inner(&$val) { inner2(&$val); } function outer(&$val) { inner(&$val); } $val = "The same."; outer(&$val); echo("val = ".$val."\n"); ... actually executes as it should on both 4.2.3 and 4.3.0 in my environment. I therefore would like to reopen the bug as one in the MSSQL extension on windows. ------------------------------------------------------------------------ [2003-01-21 00:58:49] sniper@php.net Please provide a _SHORT_ and _COMPLETE_ example script which can be used to reproduce this. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
