Parameters
-
module

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).
module
It is used internally by dbx only, and is actually the module number
mentioned above.
Examples

<?php
$link = dbx_connect(DBX_ODBC, "", "db", "username", "password", DBX_PERSISTENT)
or die("Could not connect");
echo "Connected successfully";
dbx_close($link);
?>
