dbx_connect

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

dbx_connectOpen 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"
  • 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.

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
