dbx_connect
Open a connection/database
(PHP 4 >= 4.0.6, PHP 5 <= 5.0.5, PECL dbx:1.1.0)
object dbx_connect ( mixed module, string host, string database, string username, string password [, int persistent] )
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_MYSQLor "mysql" -
DBX_ODBCor "odbc" -
DBX_PGSQLor "pgsql" -
DBX_MSSQLor "mssql" -
DBX_FBSQLor "fbsql" (available from PHP 4.1.0) -
DBX_SYBASECTor "sybase_ct" (available from PHP 4.2.0) -
DBX_OCI8or "oci8" (available from PHP 4.3.0) -
DBX_SQLITEor "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 489. 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);
?>
