Description:
------------
odbc can not return accurate result when we handle excel file use odbc.
In excel file,we handle "NUMBER" nor "VARCHAR" ,this question appear.
  we find ,this question appear when "0878-13420987" or "0878_13420987".

	$pass = '';
	$host = 'customerxls';
	$phptype='odbc';
	//database name in excel file??[main],[con_data],[con_person],[detail_data]
	$dsn = "$phptype://$user:$pass@$host";
$type=main;
	$connection=@odbc_connect($host,"","");
			$query="select a,b,d from $type";
				
				$result=@odbc_do($connection,$query);


		
    				$query_count="select count(*) from $type";  

	echo "<br>".$query."<br>";
	


	$col=count($title_array);
	for($i=0;$i<$col;$i++)
		echo $title_array[$i]."\t";
	echo "<br>"; 

	while (@odbc_fetch_row($result)){  
		echo odbc_result($result,a)."<---->".odbc_result($result,b)."<---->".odbc_result($result,y)."<br>";
		//echo $row[0]."<br>";
		
	}
