如何在php中传递Sql参数？

我写了加入查询

喜欢

$ connectionInfo = array（Database=>nsdf）;

$ conn = sqlsrv_connect（$ serverName，$ connectionInfo）;

$ result = sqlsrv_query（$ conn，SELECT CodeValue.Name，CodeValue.Latitude，CodeValue.Longitude，Area.Type，Area.Description

FROM CodeValue >
INNER JOIN区域

ON CodeValue.Id = Area.fk_SlumId）;



如何传递这些值

??

I written the Join Query
like
$connectionInfo = array( "Database"=>"nsdf");
$conn = sqlsrv_connect($serverName, $connectionInfo);
$result= sqlsrv_query($conn,"SELECT CodeValue.Name,CodeValue.Latitude,CodeValue.Longitude, Area.Type,Area.Description
FROM CodeValue
INNER JOIN Area
ON CodeValue.Id=Area.fk_SlumId");

How to pass these values
??
