How does ODBC connection work in PHP when querying an Access file?

When querying an Access file in PHP using ODBC connection, you need to first establish a connection to the Access database using the ODBC driver for Access. You then can execute SQL queries to retrieve data from the database. Make sure to handle any errors that may occur during the connection or query execution.

// Establish ODBC connection to Access database
$dsn = "Driver={Microsoft Access Driver (*.mdb)};Dbq=C:/path/to/your/database.mdb";
$conn = odbc_connect($dsn, '', '');

if (!$conn) {
    die('Could not connect to Access database: ' . odbc_errormsg());
}

// Execute SQL query to retrieve data
$query = "SELECT * FROM your_table";
$result = odbc_exec($conn, $query);

if (!$result) {
    die('Error executing query: ' . odbc_errormsg());
}

// Fetch and display data
while ($row = odbc_fetch_array($result)) {
    print_r($row);
}

// Close the connection
odbc_close($conn);
