Description:
------------
Whenever trim(...) is used on the 
  $value=trim($colstr->value);
line, the loop stops. 
However, splitting the line in two:
  $value=$colstr->value;
  $value=trim($value);
makes the loop work as expected...

Reproduce code:
---------------
$this->DBResult=$this->DBCon->Execute($sqlQuery);
$num_columns = $this->DBResult->Fields->Count();
$this->DBResultSet=null;
        for($i=0; $i < $num_columns; $i++) {
          $colstr=$this->DBResult->Fields($i);
          $name=$colstr->Name;
          toLog("DB_ADO.query","3.0: i=".$i.", Fields=".$colstr."/".$name.", num_columns=".$num_columns);
          $value=trim($colstr->value);
          toLog("DB_ADO.query","3.1: i=".$i.", Fields=".$colstr."/".$name."/".$value.", num_columns=".$num_columns);
          $this->DBResultSet[$rowcount][$name]=$value;
          toLog("DB_ADO.query","3.2: this->DBResultSet[rowcount][name]=".$this->DBResultSet[$rowcount][$name]);
        }


Expected result:
----------------
DBCon is an ADO connection to SQL Server 2000.

I expect to have the code loop through the columns found in the query, assigning each column a value in the DBResultSet array.

Seeing the following in the log:

2005.01.24-21.43:02***DB_ADO.query***1: select statement

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Ok, I can provide that, but you also need a setup with a SQL Server 2000 to replicate this fully...
 [2005-01-25 15:06 UTC] sniper@php.net 
Please read the comment again:

"no external resources" 

If you can't come up with an isolated test case we can't fix anything.
