dbx_connect -- Open a connection/database

Description

object dbx_connect ( mixed module, string host, string database, string username, string password [, int persistent] )

dbx_connect() 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 persistent parameter can be set to DBX_PERSISTENT , if so, a persistent connection will be created.

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)

The host , database , username and password parameters are expected, but not always used depending on the connect functions for the abstracted module.

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.

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);
?>
