PHP查询不适用于Oracle数据库

Question

I have a php page that is connecting to an oracle database. I am trying to print out the records from a table TEAM.

// Remember to replace 'username' and 'password'!
$conn = oci_connect('username','password','(DESCRIPTION=(ADDRESS_LIST= 
(ADDRESS=(PROTOCOL=TCP)(Host=db2.ndsu.edu)(Port=1521)))(CONNECT_DATA= 
(SID=cs)))');
echo $conn;
//put your query here
$query = "SELECT * FROM TEAM";
$stid = oci_parse($conn,$query);
oci_execute($stid,OCI_DEFAULT);

//iterate through each row
while ($row = oci_fetch_array($stid,OCI_ASSOC)) 
{
//iterate through each item in the row and echo it  
foreach ($row as $item)    
{
    echo $item.' ';
}   
echo '<br/>';}
oci_free_statement($stid);
oci_close($conn);
?>

I did change the user name and password. The echo $conn is printing out "Resource id #4" so I believe I am connected to the database.
