我试图抓住数组中的最大值,同时仍然保留项目标签.我知道我可以通过运行sort()来做到这一点,但是如果我这样做,我就会丢失标签 - 这使得它对我需要的东西毫无意义.这是阵列:

array("a"=>1,"b"=>2,"c"=>4,"d"=>5);

有任何想法吗？

我需要在谷歌地图上显示一个纬度/经度位置数组作为数组(使用v3 api).我的代码在下面 - 任何想法为什么它不起作用？(控制台中没有错误)

var locs = ["51.38254, -2.362804", "51.235249, -2.297804", "51.086126, -2.210767", "51.084519, -2.262813", "51.175994, -2.159207", "51.132978, -2.213939", "51.207289, -2.181474", "51.321724, -2.205518", "51.317219, -2.210649", "50.700816, -1.925721", "50.719979, -2.074488", "50.810063, -1.919034", "50.785094, -1.849725", "50.842648, -1.777575", "50.723047, -1.902297", "50.743044, -1.880132", "51.71355, 0.154967", "51.992676, 0.602668", "52.355964, -1.486877", "53.523356, -1.107254", "51.87591, -2.235986", "51.670729, -1.934476", "51.542953, -0.28102", "51.52132, 0.098986", "52.271354, 0.788806", "51.346031, -0.478255", "51.263343, -1.140235", "51.481736, -1.089953", "51.476566, -0.514911", "51.505462, -0.555614", "51.558631, -1.78224", "51.351101, -1.995069", "51.380722, -2.039105", "51.416719, -2.124294", "51.42063, -2.133049", "51.533076, -1.925663", "51.348518, …

我正在使用Minecraft服务器仪表板,其中一个功能是备份和恢复您的世界(目录).我已经有了一个函数(见下文),但是,正如你可能看到的那样,代码非常糟糕.谁知道更好,更清洁的功能？

function backupOrRestoreWorld($source,$target){
    foreach(glob($target.'*.*')as$v){
        unlink($v);
    }
    if(is_dir($source)){
        @mkdir($target);
        $d=dir($source);
        while(FALSE!==($entry=$d->read())){
            if($entry=='.'||$entry=='..'){
                continue;
            }
            $Entry=$source.'/'.$entry;
            if(is_dir($Entry)){
                backupOrRestoreWorld($Entry,$target.'/'.$entry);
                continue;
            }
            copy($Entry,$target.'/'.$entry);
        }
        $d->close();
    }
    else{
        copy($source,$target);
    }
    if($source == "server/world"){
        return "World backed up.";
    }
    else {
        return "World restored from backup.";
    }
}
