    dbx_connect

    (PHP 4 >= 4.0.6, PHP 5 < 5.1.0, PECL dbx >= 1.1.0)

    dbx_connect — Open a connection/database

    Description

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

    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"
    • DBX_SYBASECT or "sybase_ct"
    • DBX_OCI8 or "oci8"
    • DBX_SQLITE or "sqlite"

    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.

    If you get an error:
    "Error while trying to retrieve text for error ORA-12154"
    means that you didn't set the ORACLE_HOME, TNS_ADMIN and ORACLE_BASE variable.
    If you are sure it's set as a system variable, you could solve the problem by use:
    putenv('ORACLE_HOME=/your/oracle/home/beforebin');

    I have been using dbx for a product at work and the need to use SQLite as a database popped up. However, I couldn't find any references to using it with dbx other than that you could and since SQLite doesn't seem to do the username password thing I was a little confused as to how to use it in dbx.

    With a little research it seems that when using dbx_connect you only need to fill in the module name ('DBX_SQLITE') and the database (the file name for the database!) to get it working. e.g.

    $link = dbx_connect(DBX_SQLITE, "", "some.db", "", "");

    thought someone might find it useful, especially since it no longer required additional dll's in version 5.x

    The advantage that this has over Pear, Adob, and even Eclipse is speed. As some one put elsewhere,

    "Yes, there is an advantage: Speed!
    ext/dbx is written in C and has to be compiled into PHP. It's just faster then the PEAR classes."

    Cheers,

    Currently to connect to the PostgreSQL backend, you have to supply both a username, and a password or the dbx pgsql module attempts to connect as "nobody".

    Pear::DB seems like a better idea than this.  See http://pear.php.net
