PHP 获取Apache版本和其他已安装的软件版本作为关联数组

Posted 2021-05-14

function getServerSoftware($key = 'SERVER_SOFTWARE')
{
	$regex = "/(?<software>\w+)\/(?<version>[0-9.a-z]*)/";
		
	if(isset($_SERVER[$key]) && preg_match_all($regex, $_SERVER[$key], $arr))
		return array_combine($arr['software'], $arr['version']);
	else
		return array();
}

//USAGE EXAMPLE

//get array
$serverInfo = getServerInfo();

//print apache version
echo $serverInfo['Apache'];

//print all information
foreach($serverInfo as $software=>$version) echo "{$software}: {$version}<br>\n";
