PHP makes it easy to write scripts that access databases, enabling you to create dynamic web pages that incorporate database content. PHP includes several pecialized database-access interfaces that take the form of separate sets of functions for each database system. There is one set for MySQL, another for Inter-Base, another for PostgreSQL, and so forth. However, having a different set of functions for each database makes PHP scripts non-portable at the lexical (source code) level. For example, the function for issuing an SQL statement is named mysql_query(), ibase_query(), or pg_exec(), depending on whether you are using MySQL, InterBase, or PostgreSQL.
