A PHP 4 extension for this release of Berkeley DB is
|
||
included in the distribution package. It can either either
|
||
link directly against the installed Berkeley DB library (which
|
||
is necessary for running in a non-Apache/mod_php4
|
||
environment), or against mod_db4, which provides additional
|
||
safety when running under Apache/mod_php4.
|
||
</p>
|
||
<p>
|
||
For installation instructions, see the
|
||
<code class="filename">INSTALL</code> file that resides in the
|
||
<code class="literal">lang/php_db4</code> directory in your
|
||
Berkeley DB distribution.
|
||
</p>
|
||
<p>
|
||
The PHP extension provides the following classes, which
|
||
mirror the standard Berkeley DB C++ API.
|
||
</p>
|
||
<pre class="programlisting">class Db4Env {
|
||
function Db4Env($flags = 0) {}
|
||
function close($flags = 0) {}
|
||
function dbremove($txn, $filename, $database = null, $flags = 0) {}
|
||
function dbrename($txn, $file, $database, $new_database,
|
||
$flags = 0) {}
|
||
function open($home, $flags = DB_CREATE | DB_INIT_LOCK |
|

|

|

|

|
||
function txn_checkpoint($kbytes, $minutes, $flags = 0) {}
|
||
}
|
||
|
||
class Db4 {
|
||
function Db4($dbenv = null) {} // create a new Db4 object using
|
||
// the optional DbEnv
|

function open($txn = null, $file = null, $database = null,
|

$flags = DB_CREATE, $mode = 0) {}
|

|

|

|

|

|

|

function truncate($txn = null, $flags = 0) {}
|

|

|
||
function put($key, $data, $flags = 0) {}
|
||
}</pre>
|

<p>
|
||
The PHP extension attempts to be "smart" for you by:
|
||
</p>
|
||
<div class="orderedlist">
|
||
<ol type="1">
|
||
<li>
|
||
Auto-committing operations on transactional
|
||
databases if no explicit Db4Txn object is
|
||
specified.
|
||
</li>
|
||
<li>
|
||
Performing reference and dependency checking to
|
||
insure that all resources are closed in the correct
|
||
order.
|
||
</li>
|
||
<li>
|
||
Supplying default values for flags.
|
||
</li>
|
||
</ol>
