Grab newest PHP version

[intenz]

Hello, I am trying to grab the newest version of PHP-stable (4.3.6).

This is how I do it...

$skra = implode( '', file( 'http://is2.php.net/ChangeLog-4.php' ) );
$skra = str_replace( "\n", '', $skra );
$skra = str_replace( "\r\n", '', $skra );
$search = ereg( '</a><h3>Version (.*)</h3><b>', $skra, $content );
$temp = explode( '<', $content[1] );
echo $temp[0];

I can't use this, because this takes too much time to load.

Do you know of any better way to grab this?
And also the newest version available (5.0.0RC1).

Thanks in advance.
