Description:
------------
We migrated an application from Apache/mssql to IIS/mssql.  All scripts, sprocs, etc stayed the same.  Only change was to the database driver.  We have a problem in that the mssql_bind now no longer works in the foreach loop.  The exact same script does work if we explicitly bind each variable.

//this doesn't work:
        $sp_name = "proc_entity_types";
	$paramArray = array();
        $paramArray['mode'] = "V";
        $paramArray['entity_typeId'] = "";
	$paramArray['entity_type'] = "";
	$paramArray['retail_type'] = "";
	$paramArray['document_mapping_type'] = "";
		
        $procRes = mssql_init($sp_name);
        foreach($paramArray as $key=>$value) {                
                $value = trim($value);
		mssql_bind($procRes,"@$key",&$value,SQLVARCHAR);
        }

//this does work(!)
        $procRes = mssql_init("proc_entity_types");
	$mode = "V";
	$entity_typeId = "";
	$retail_type = "";
	$document_mapping_type = "";
	
	 mssql_bind($procRes,"@mode",&$mode,SQLVARCHAR);
	 mssql_bind($procRes,"@entity_typeId",&$entity_typeId,SQLVARCHAR);
	 mssql_bind($procRes,"@entity_type",&$entity_type,SQLVARCHAR);
 	 mssql_bind($procRes,"@retail_type",&$retail_type,SQLVARCHAR);
	 mssql_bind($procRes,"@document_mapping_type",&$document_mapping_type,SQLVARCHAR);
	 
	 $result = mssql_execute($procRes);

//*********/

note: we've tried...
1) mssql_bind($procRes,"@$key",&$value,SQLVARCHAR); 
2) mssql_bind($procRes,'@'.$key,&$value,SQLVARCHAR);
3) mssql_bind($procRes,'@'.$key,$value,SQLVARCHAR);

We've tried while loops instead of foreach... 

And again, it all worked fine in apache connecting to the same db.

Test script:
---------------
        //doesn't work:
        $sp_name = "proc_entity_types";
	$paramArray = array();
        $paramArray['mode'] = "V";
        $paramArray['entity_typeId'] = "";
	$paramArray['entity_type'] = "";
	$paramArray['retail_type'] = "";
	$paramArray['document_mapping_type'] = "";
		
        $procRes = mssql_init($sp_name);
        foreach($paramArray as $key=>$value) {                
                $value = trim($value);
		mssql_bind($procRes,"@$key",&$value,SQLVARCHAR);
        }

       //this does
        $procRes = mssql_init("proc_entity_types");
	$mode = "V";
	$entity_typeId = "";
	$retail_type = "";
	$document_mapping_type = "";
	
	 mssql_bind($procRes,"@mode",&$mode,SQLVARCHAR);
	 mssql_bind($procRes,"@entity_typeId",&$entity_typeId,SQLVARCHAR);
	 mssql_bind($procRes,"@entity_type",&$entity_type,SQLVARCHAR);
 	 mssql_bind($procRes,"@retail_type",&$retail_type,SQLVARCHAR);
	 mssql_bind($procRes,"@document_mapping_type",&$document_mapping_type,SQLVARCHAR);
	 
	 $result = mssql_execute($procRes);
