Oracle Tips by Burleson 


OCI stands for “Oracle Call Interface”. The OCI8 module introduced in this chapter is from PHP5. PHP4 supported both the OCI8 module and an old OCI module used to connect to Oracle7 and earlier versions. PHP 5 no longer supports the old OCI calls that originated from version 6 of Oracle RDBMS.   This chapter describes the OCI8 module in detail and consists of the following sections:

  • Connecting to Oracle - This section describes various methods for establishing database connections.

  • Handling Errors - This section presents examples for handling errors by using the oci_error function.

  • Executing SQL - This section reveals the stages of SQL execution and the description and use of the oci_execute() function.

  • Binding and Defining Variables - This section describes placeholders and how to “relate” them to script variables. It shows how to execute PL/SQL procedures and how to bind values to parameters. 

  • Auxiliary OCI8 Functions - This section displays the results of a query as a HTML table in example form.

  • Oracle Cursors - This section shows how to bind variables to cursors.

  • Large Objects - This section reveals what large objects are used for, and how to load large documents into a database.

  • Get Method - This section describes combining the GET method with PL/SQL, and how to invoke a PHP script with parameters encoded in the URL.

In many ways, this chapter is central for this book as it describes in great detail the most basic method that can be used to establish a communication between an Oracle database and a PHP script.
