Opens a connection to a database.
The module
parameter can be either a string or a constant, though the latter form is preferred. The possible values are given below, but keep in mind that they only work if the module is actually loaded.
-
DBX_MYSQL
or "mysql" -
DBX_ODBC
or "odbc" -
DBX_PGSQL
or "pgsql" -
DBX_MSSQL
or "mssql" -
DBX_FBSQL
or "fbsql" -
DBX_SYBASECT
or "sybase_ct" -
DBX_OCI8
or "oci8" -
DBX_SQLITE
or "sqlite"
The SQL server host
The database name
The username
The password
The persistent
parameter can be set to DBX_PERSISTENT
, if so, a persistent connection will be created.
Returns an object on success, FALSE
on error. If a connection has been made but the database could not be selected, the connection is closed and FALSE
is returned.
The returned object has three properties:
- database
- It is the name of the currently selected database.
- handle
-
It is a valid handle for the connected database, and as such it can be used in module-specific functions (if required).
<?php $link = dbx_connect(DBX_MYSQL, "localhost", "db", "username", "password"); mysql_close($link->handle); // dbx_close($link) would be better here ?>
- module
- It is used internally by dbx only, and is actually the module number mentioned above.
