}
for reading HTTP status codes works, but is not ideal. Moreover, the cURL extension is not installed by default at every web host.
It can be done much more simply.
$info = get_headers( $url );
$status_code = $info[0];
get_headers gibt fast alle Header-Infos in ein Array zurück.

This is greatly simplified with a PHP class.
$data = array(
'IE7' => 22,
'IE6' => 30.7,
'IE5' => 1.7,
'Firefox' => 36.5,
'Mozilla' => 1.1,
'Safari' => 2,
'Opera' => 1.4,
);
$chart = new googChart();
$chart->setChartAttrs( array(
'type' => 'pie',
'data' => $data,
'size' => array( 300, 200 )
));
echo $chart;

A practical example is the calculation of distances. In some projects I calculated this with PHP.
It can also be done directly with SQL
SELECT *, SQRT(POW(L2.lat - L1.lat, 2) + POW(L2.lng - L1.lng, 2)) AS Distance

Could it be that more attention will be paid to Java compatibility? Possibly.
If anyone has this concern, MySQL will continue to remain open source. However, Sun could use this to push its programming language Java more aggressively, as Java has recently been losing ground on the web to PHP and Ruby. ]]>
