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" (available from PHP 4.1.0)
DBX_SYBASECT or "sybase_ct" (available from PHP
4.2.0)
DBX_OCI8 or "oci8" (available from PHP 4.3.0)
DBX_SQLITE or "sqlite" (PHP 5)
host
The SQL server host
database
The database name
username
The username
password
The password
persistent
The persistent parameter can be set to
DBX_PERSISTENT, if so, a persistent connection
will be created.
The host, database,
username and password
parameters are expected, but not always used depending on the connect
functions for the abstracted module.
Return Values
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.
Examples
Example 1. dbx_connect() example
<?php $link = dbx_connect(DBX_ODBC, "", "db", "username", "password", DBX_PERSISTENT) or die("Could not connect");
