示例
示例 #1 List Columns of a stored Procedure
<?php
$conn = odbc_connect($dsn, $user, $pass);
$columns = odbc_procedurecolumns($conn, 'TutorialDB', 'dbo', 'GetEmployeeSalesYTD;1', '%');
while (($row = odbc_fetch_array($columns))) {
print_r($row);
break; // further rows omitted for brevity
}
?>以上示例的输出类似于：
