Natively Connect to MariaDB Data in PHP

Drop the CData ODBC Driver for MariaDB into your LAMP or WAMP stack to build MariaDB-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to MariaDB data, execute queries, and output the results.

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

The Server and Port properties must be set to a MariaDB server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, the tables from all databases are reported.

Establish a Connection

Open the connection to MariaDB by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC MariaDB Source","user","password");

Connections opened with are closed when the script ends. Connections opened with the method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC MariaDB Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the function.

$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE ShipCountry = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC MariaDB Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE ShipCountry = ?");
$success = odbc_execute($query, array('USA'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC MariaDB Source","user","password");
$query = odbc_exec($conn, "SELECT ShipName, ShipCity FROM Orders");
 

Process Results

Access a row in the result set as an array with the function.

$conn = odbc_connect("CData ODBC MariaDB data Source","user","password");
$query = odbc_exec($conn, "SELECT ShipName, ShipCity FROM Orders");
while($row = odbc_fetch_array($query)){
 echo $row["ShipName"] . "\n";
}

Display the result set in an HTML table with the function.

$conn = odbc_connect("CData ODBC MariaDB data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE ShipCountry = ?");
$success = odbc_execute($query, array('USA'));
if($success)
 odbc_result_all($query);
