The following code example shows how to bind parameters to create parameterized statements.

Reusable Statements

The odbc_prepare function creates prepared statements, which can be re-used across multiple calls to odbc_execute. The statement object can be used to fetch results like a non-parameterized query.

$stmt = odbc_prepare($cnx, "SELECT Id, AddressLines FROM Constituents WHERE Type = ?");

odbc_execute($stmt, array("Home 1"));
while ($row = odbc_fetch_array($stmt)) {
    echo "Id = ", $row["Id"], "\n";
    echo "AddressLines = ", $row["AddressLines"], "\n";
}

odbc_execute($stmt, array("Home 2"));
while ($row = odbc_fetch_array($stmt)) {
    echo "Id = ", $row["Id"], "\n";
    echo "AddressLines = ", $row["AddressLines"], "\n";
}
