PHP格式如何制作52.593800,21.448850格式52°35’37.68“,21°26’55.86”喜欢google http://maps.google.pl/maps?hl=pl&t=m&q=52.593800,21.448850吗?
解决方法:
<?PHP
function DMStoDEC($deg,$min,$sec)
{
// Converts DMS ( degrees / minutes / seconds )
// to decimal format longitude / latitude
return $deg+((($min*60)+($sec))/3600);
}
function DECtoDMS($dec)
{
// Converts decimal longitude / latitude to DMS
// ( degrees / minutes / seconds )
// This is the piece of code which may appear to
// be inefficient, but to avoid issues with floating
// point math we extract the integer part and the float
// part by using a string function.
$vars = explode(".",$dec);
$deg = $vars[0];
$tempma = "0.".$vars[1];
$tempma = $tempma * 3600;
$min = floor($tempma / 60);
$sec = $tempma - ($min*60);
return array("deg"=>$deg,"min"=>$min,"sec"=>$sec);
}
将数组更改为所需的字符串应该是微不足道的.
