NAME
SelectSaver - save and restore selected file handle SYNOPSIS
use SelectSaver; { my $saver = SelectSaver->new(FILEHANDLE); # FILEHANDLE is selected } # previous handle is selected { my $saver = SelectSaver->new; # new handle may be selected, or not } # previous handle is selected DESCRIPTION
A "SelectSaver" object contains a reference to the file handle that was selected when it was created. If its "new" method gets an extra parameter, then that parameter is selected; otherwise, the selected file handle remains unchanged. When a "SelectSaver" is destroyed, it re-selects the file handle that was selected when it was created. perl v5.16.2 2012-08-26 SelectSaver(3pm)

dbx_connect - Open a connection/database

SYNOPSIS
object dbx_connect (mixed $module, string $host, string $database, string $username, string $password, [int $persistent]) DESCRIPTION
Opens a connection to a database. PARAMETERS
o $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. o DBX_MYSQL or "mysql" o DBX_ODBC or "odbc" o DBX_PGSQL or "pgsql" o DBX_MSSQL or "mssql" o DBX_FBSQL or "fbsql" o DBX_SYBASECT or "sybase_ct" o DBX_OCI8 or "oci8" o DBX_SQLITE or "sqlite" o $host - The SQL server host o $database - The database name o $username - The username o $password - The password o $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: o database - It is the name of the currently selected database. o 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 ?> o module - It is used internally by dbx only, and is actually the module number mentioned above.
