[, int $persistent

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"
DBX_SYBASECT or "sybase_ct"
DBX_OCI8 or "oci8"
DBX_SQLITE or "sqlite"
hostThe SQL server host
databaseThe database name
usernameThe username
passwordThe 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.
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:
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
?>
Example #1 dbx_connect() example
<?php
$link = dbx_connect(DBX_ODBC, "", "db", "username", "password", DBX_PERSISTENT)
or die("Could not connect");
echo "Connected successfully";
dbx_close($link);
?>
Note:
Always refer to the module-specific documentation as well.
