Open a connection/database

dbx_connect

(PHP 4 >= 4.0.6, PHP 5 <= 5.0.5, PECL dbx:1.1.0)

dbx_connect — Open a connection/database

Description

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

Opens a connection to a database.

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).

<?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");

echo "Connected successfully";
dbx_close($link);
?>

Notes

Note: Always refer to the module-specific documentation as well.
