如何用php创新的access数据库，并在其中建立一个表

<?php

$cat = new COM("ADOX.Catalog");

$cat->Create("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=g:/test1.mdb");

$cat = null;

$sql = "CREATE TABLE table_name(int_field INT)";

$conn = new COM("ADODB.Connection");

$conn->Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=g:/test1.mdb");

$conn->Execute($sql);

$conn->Close();

$conn  = null;

?>
