Interacting with Other DBMSs Using PHP
Interacting with other relational DBMSs is similar to using MySQL. In this section, we outline the key functions to access Microsoft SQL Server, ODBC-compliant, Oracle, and PostgreSQL DBMSs. We illustrate how to interact with different DBMSs by presenting four rewritten versions of Example 4-1 that include different DBMS functionality.
Functions for accessing other databases, including Informix and Sybase, can be found in the PHP manual. For DBMSs that are not supported natively by PHP, ODBC can usually be used; we discuss ODBC later in this section.
