Retrieve value from database (got the data with extra spaces)

[danh2]

Hello i am having some issues,

when i try to pull some values from my db i get them with extra spaces like "DATA "

the code i am using for it is

		function doQuery($query)
		{
			$parameters = func_get_args();
			array_shift($parameters);

			$this->queryResult = $this->_doQuery($query, $parameters);
			if ($this->queryResult == -1)
				$this->getError();
			else
				parent::Success();


			return $this->queryResult;
		}
		
		function _doQuery($query, $parameters)
		{
			if (!parent::isConnected())
			{
				if (!$this->doConnect())
					return -1;
			}
			
			if ($this->result)
				@odbc_free_result($this->result);
			
			parent::Query();
			if (sizeof($parameters) > 0)
			{
				$this->result = @odbc_prepare($this->conn, $query);
				if (!$this->result)
					return -1;
					
				$result = @odbc_execute($this->result, $parameters);
				if (!$result)
					return -1;
			}
			else
			{
				$this->result = @odbc_exec($this->conn, $query);
				if (!$this->result)
					return -1;
			}
			return @odbc_num_rows($this->result);
		}


		function doRead($fetch = DB_FETCH_ARRAY)
		{
			if ($fetch == DB_FETCH_ROW)
			{
				return @odbc_fetch_row($this->result);
			}
			else
			{
				return @odbc_fetch_array($this->result);
			}
		}

$db->doQuery('SELECT strAccountID, strCharID, strClientIP, nServerNo FROM CURRENTUSER WHERE strAccountID = ? AND strClientIP = ?', $_POST[CPD_ID], $this->getRemoteIP());
				
				$row = $db->doRead();
				if (strcmp($_POST[CPD_ID], $row['strAccountID']) !== 0)

now the issue is with getting "$row['strAccountID']"

the value that is it giving it "database            "
and then it is not matching.

any idie what it is like that?

thanks.

I don't use ODBC, but I can't see the library itself doing this.
Are you using a varchar type field for your database, or is it a char type field? That strAccountID for example appears to have 20 chars in total, which would be consistent with a char(20) datatype. MySQL for example would right pad the string to the size required to fit in the char field. Instead we'd use varchar to allow up to but not pad the size of the field in question. Not sure what db you are using though, so I can't really help on that.
PHP wise you can simply rtrim() the data to remove the excess padding.
