再用用程序时,一般需要对php版本号整数化后进行判断,从而确定输出。
$temp=explode(".",phpversion()); //以数组形式获取版本号
$num=count($temp); //计算数组中的元素数量
$phpver=0;
switch($num)
{
cas 3:
$phpver=$phpver+(intval($temp[2]));
cas 2:
$phpver=$phpver+(intval($temp[1]*10);
cas 1:
$phpver=$phpver+(intval($temp[0]*100);
default:
}
echo $phpver;
?>
