DB is a database abstraction layer providing:
* an OO-style query API
* portability features that make programs written for one DBMS work with
other DBMS's
* a DSN (data source name) format for specifying database servers
* prepare/execute (bind) emulation for databases that don't support it
natively
* a result object for each query response
* portable error codes
* sequence emulation
* sequential and non-sequential row fetching as well as bulk fetching
* formats fetched rows as associative arrays, ordered arrays or objects
* row limit support
* transactions support
* table information interface
* DocBook and phpDocumentor API documentation
.
DB layers itself on top of PHP's existing
database extensions.
.
Drivers for the following extensions pass
the complete test suite and provide
interchangeability when all of DB's
portability options are enabled:
.
fbsql, ibase, informix, msql, mssql,
mysql, mysqli, oci8, odbc, pgsql,
sqlite and sybase.
.
There is also a driver for the dbase
extension, but it can't be used
interchangeably because dbase doesn't
support many standard DBMS features.
.
DB is compatible with PHP 5 and PHP 7.
