Natively Connect to MariaDB Data in PHP
The CData ODBC driver for MariaDB enables you to create PHP applications with connectivity to MariaDB data. Leverage the native support for ODBC 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 odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.
$conn = odbc_connect("CData ODBC MariaDB Source","user","password");
Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect 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 odbc_prepare function.
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE ShipCountry = ?");
Execute Queries
Execute prepared statements with odbc_execute.
$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 odbc_exec.
$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 odbc_fetch_array 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 odbc_result_all 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);
More Example Queries
You will find complete information on the driver's supported SQL in the help documentation. The code examples above are MariaDB-specific adaptations of the PHP community documentation for all ODBC functions.
