php linux vs window version

Come across interesting fact;

In linux

echo $_SERVER['SERVER_NAME']; //somedomain.org
echo $_SERVER['HTTP_HOST']; //somedomain.org


In window

echo $_SERVER['SERVER_NAME']; //localhost
echo $_SERVER['HTTP_HOST']; //somedomain.org


change associated array to indexed array

sometimes i want to change this form of array

array('position'=> array('data1', 'data2'..)
'year' => array('year1', 'year2'..)
)


to this

array(0 => array('position'=> 'data1',
'year' => 'year1'),
1 => array('position' => 'data2',
'year' => 'year2')


here is how i do it.

function array_group($data)
{
$result = array();
foreach($data as $key=>$rows)
foreach($rows as $i=>$value)
$result[$i][$key] = $value;

return $result;
}


PHP gotcha

Debian wheezy version of php5-fpm (5.4.4-7) using socket instead of server running on local port 9000.
Need to update nginx configuration files to point to php5-fpm socket.

#fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/var/run/php5-fpm.sock;
}
