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, DueDate FROM Invoices WHERE Status = ?");

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

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