我最近创建了一个if语句脚本,它根据数字表示的内容设置变量.在意识到脚本相当长并且最有可能以更有效的方式完成之后,我在互联网上查看并没有找到太多结果.这是我的剧本

            if ($row[position] == 1){
                $variable = 1;
            } elseif ($row[position] == 2){
                $variable = 1;
            } elseif ($row[position] == 3){
                $variable = 2;
            } elseif ($row[position] == 4){
                $variable = 2;
            } elseif ($row[position] == 5){
                $variable = 3;
            } elseif ($row[position] == 6){
                $variable = 3;
            } elseif ($row[position] == 7){
                $variable = 4;
            } elseif ($row[position] == 8){
                $variable = 4;
            } elseif ($row[position] == 9){
                $variable = 5;
            } elseif ($row[position] == 10){
                $variable = 5; …

如果你看到任何YouTube视频,https://www.youtube.com/watch？v = s8yznE7rkiM,当您重新调整页面尺寸时,视频播放器将根据宽高比而不是仅仅改变只需重新调整它的大小.这很有用,因为它不显示黑条.我的尝试并没有那么成功.
