This problem has been reported by others, but either closed or marked as BOGUS, which is not the case, as I've reproduced this on both development and deployed systems. Reproduce code: --------------- CREATE PROCEDURE REC_PROC_INSERT_MS_INTF @UCODE UNIQUEIDENTIFIER, @PHONE VARCHAR(10), @ACCOUNT VARCHAR(25), @EALOC VARCHAR(38), @TIME DATETIME, @RECID UNIQUEIDENTIFIER, @PRBSTR VARCHAR(30) AS SELECT @UCODE as ucode, @PHONE as phone, @ACCOUNT as account, @EALOC as ealoc, @TIME as time, @RECID as recid, @PRBSTR as prbstr RETURN 1 GO $sp = mssql_init('REC_PROC_INSERT_MS_INTF',$dblink->dbresource); mssql_bind($sp,"RETVAL",&$rc,SQLINT4,TRUE,TRUE,4); mssql_bind($sp,"@UCODE",$ucode,SQLVARCHAR,FALSE,FALSE,strlen($ucode)); mssql_bind($sp,"@PHONE",$phone,SQLVARCHAR,FALSE,FALSE,10); mssql_bind($sp,"@ACCOUNT",$account,SQLVARCHAR,FALSE,FALSE,25); mssql_bind($sp,"@EALOC",$ealoc,SQLVARCHAR,FALSE,FALSE,38); mssql_bind($sp,"@TIME",$currtime,SQLVARCHAR,FALSE,FALSE,strlen($currtime)); mssql_bind($sp,"@RECID",$recId,SQLVARCHAR,FALSE,FALSE,strlen($recId)); mssql_bind($sp,"@PRBSTR",$problem,SQLVARCHAR,FALSE,FALSE,30); $result = mssql_execute($sp); if($result){ $row = mssql_fetch_array($result); global $log; $log->Writelog(var_export($row,true)); } Expected result: ---------------- I would expect the empty strings to stay empty. This causes major problems with NON-NULLABLE SQL fields!!! array ( 0 => 'ükÁ#ðÌæMTèÇS±í°', 'ucode' => 'ükÁ#ðÌæMTèÇS±í°', 1 => '', 'phone' => '', 2 => '', 'account' => '', 3 => '423998059-130628001', 'ealoc' => '423998059-130628001', 4 => '2007-02-07 16:20:54', 'time' => '2007-02-07 16:20:54', 5 => 'g÷r}Q\'[EMAIL PROTECTED]', 'recid' => 'g÷r}Q\'[EMAIL PROTECTED]', 6 => '', 'prbstr' => '', ) Actual result: -------------- when any of the strings (not uniqueidentifiers) are set to an empty string ($phone = '') the following is received from the var_export() array ( 0 => 'ükÁ#ðÌæMTèÇS±í°', 'ucode' => 'ükÁ#ðÌæMTèÇS±í°', 1 => NULL, 'phone' => NULL, 2 => NULL, 'account' => NULL, 3 => '423998059-130628001', 'ealoc' => '423998059-130628001', 4 => '2007-02-07 16:20:04', 'time' => '2007-02-07 16:20:04', 5 => 'g÷r}Q\'[EMAIL PROTECTED]', 'recid' => 'g÷r}Q\'[EMAIL PROTECTED]', 6 => NULL, 'prbstr' => NULL, ) the GUIDS look like garbage, but are correct. The strings however are all NULL if they were sent in as '' This is what var_export() reports if all strings are set to ' ' (one space) array ( 0 => 'ükÁ#ðÌæMTèÇS±í°', 'ucode' => 'ükÁ#ðÌæMTèÇS±í°', 1 => ' ', 'phone' => ' ', 2 => ' ', 'account' => ' ', 3 => '423998059-130628001', 'ealoc' => '423998059-130628001', 4 => '2007-02-07 16:20:54', 'time' => '2007-02-07 16:20:54', 5 => 'g÷r}Q\'[EMAIL PROTECTED]', 'recid' => 'g÷r}Q\'[EMAIL PROTECTED]', 6 => ' ', 'prbstr' => ' ', ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40394&edit=1
