DB

Database Abstraction Layer

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 PHPDoc API documentation DB layers itself on top of PHP's existing database extensions. The currently supported extensions are: dbase, fbsql, interbase, informix, msql, mssql, mysql, mysqli, oci8, odbc, pgsql, sqlite and sybase. DB is compatible with both PHP 4 and PHP 5. ssb Stig Sæther Bakken stig@php.net developer cox Tomas V.V.Cox cox@idecnet.com developer chagenbu Chuck Hagenbuch chuck@horde.org helper danielc Daniel Convissor danielc@analysisandsolutions.com lead 1.6.5 2004-07-14 PHP License stable ============= BUGS FIXED: * DB.php Add rawurldecode() to database portion of DSN. Bug 1826. (danielc) * common, dbase, fbsql, ibase, oic8, pgsql: When using resources as array index, convert to int first. http://bugs.php.net/28879 (danielc) * mysqli: Adjust tableInfo() so it can deal with changes made to mysqli_fetch_field()'s behavior. Add the $mysqli_flags and $mysqli_types properties as part of this effort. (danielc) mysql >= 4.0 doesn't need WHERE 1=1 hack for DELETE. (danielc) * pgsql: Adjust getListOf('tables') to accommodate the addition of sql_* core tables in PostgreSQL 7.4.2. Bug 1549. (Patch by yiwakiri and jpbarrette) * sybase: Use 'charset' and 'appname' from DSN in sybase connect. Bug 1812. (danielc) Simplify connect by setting $dsninfo['password'] to false if it's empty. Reworks hack for PEAR bug 631. (danielc) PEAR
