This section provides a walk-through to writing ODBC data access code to Apache Phoenix in PHP, using the build-in Unified ODBC API.

Connecting from PHP

See Getting Started for the prerequisite information you need to deploy the driver and configure the connection to Apache Phoenix.

Dependencies describes the necessary steps to configure Unified ODBC. Once it is prepared, refer to Connecting to connect to Apache Phoenix.

Executing SQL

Use Unified ODBC functions to execute SQL on Apache Phoenix:

• See Querying Data to execute SELECT statements and iterate over the results.
• See Modifying Data to execute other SQL data manipulation statements.
• See Parameterized Statements to execute parameterized statements. Parameterized statements provide a means to efficiently execute queries more than once and to mitigate SQL injection attacks.
