php – 使用不确定数据对数组进行排序

前端之家收集整理的这篇文章主要介绍了php – 使用不确定数据对数组进行排序前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在为一个浏览器游戏制作一个脚本,它将生成一个随机动物,供玩家在0-5标记的任何地方进行战斗.该动物上的标记随机生成的,并被输入到自定义的imagick函数中,该函数将按照它们出现在数组中的顺序添加它们.

虽然标记随机决定的,但它们应该如何出现在动物上有很多规则,例如“全身”区域中的标记显示在“腹部”区域的标记之上.为了更好地解释,到目前为止我将附上测试仪的图像:

因此要打破这个随机生成的动物的5个标记,眼影标记属于眼睛区域,属于尾巴,条纹属于全身,阿帕卢萨属于背部,霍加皮属于腿.现在的订单只是在脚本循环通过数据库随机选择的标记添加,所以okapi(腿上的条纹)位于顶部,因为它是数组中的最后一个,并且添加了最后一个.但是遵循顺序规则,数组中的最后一个应该是条纹(身体上的水平条纹),因为全身标记在顶部.

以下是选择标记代码,这是使用Laravel引擎完成的:

// Determine number of markings
    $num = mt_rand(1,10);

    if ($num == 1) {
        $markingNum = 0;
    } elseif ($num > 1 && $num < 4) {
        $markingNum = 1;
    } elseif ($num > 4 && $num < 6) {
        $markingNum = 2;
    } elseif ($num > 6 && $num < 8) {
        $markingNum = 3;
    } elseif ($num > 8 && $num < 10) {
        $markingNum = 4;
    } else {
        $markingNum = 5;
    }

    // Calculate Marking type and color
    $markings = array();

    if ($markingNum > 0) {
        for ($m = 0 ; $m < $markingNum; $m++) {
            // Set color values (pulls from the "pallet" selected earlier in the code,which will determine the range of color that marking can be)
            if ($m == 1) {
                $pal = $pallet->marking1;
            } elseif ($m == 2) {
                $pal = $pallet->marking2;
            } elseif ($m == 3) {
                $pal = $pallet->marking3;
            } elseif ($m == 4) {
                $pal = $pallet->marking4;
            } else {
                $pal = $pallet->marking5;
            }

            // Pull prevIoUs marking info
            if (count($markings) != 0) {
                    $prevIoUs = DataMarking::whereIn('name',array_keys($markings))->get();

                    // This pulls the regions of the current markings in the array so it won't select a region that already has a marking.
                    foreach ($prevIoUs as $p) {
                        $regions[$p->region] = $p->name;
                    }

                    // Uncommon marking (10% chance)
                    $r = mt_rand(1,10);

                    if ($r == 10) {
                        $marking = DataMarking::where('rarity',1)
                                              ->where('public',1)
                                              ->whereNotIn('name',array_keys($markings))
                                              ->whereNotIn('region',array_keys($regions))
                                              ->orderByRaw("RAND()")
                                              ->first();
                    // Common markings
                    } else {
                        $marking = DataMarking::where('rarity',0)
                                              ->where('public',array_keys($regions))
                                              ->orderByRaw("RAND()")
                                              ->first();
                    }

                    // Colors marking
                    if ($pal == 0) {
                        $markingColor = rand_color();
                    } else {
                        $range = ColorRange::where('id',$pal)->firstOrFail();
                        $markingColor = "#" . mixRange(substr($range->start_hex,1),substr($range->end_hex,1));
                    }

                    $markings[$marking->name] = $markingColor;
                } else {
                // Uncommon marking (10% chance)
                $r = mt_rand(1,10);

                if ($r == 10) {
                    $marking = DataMarking::where('rarity',1)
                                          ->where('public',1)
                                          ->orderByRaw("RAND()")->first();
                // Common marking
                } else {
                    $marking = DataMarking::where('rarity',0)
                                          ->where('public',1)
                                          ->orderByRaw("RAND()")->first();
                }

                // Colors marking
                if ($pal == 0) {
                    $markingColor = rand_color();
                } else {
                    $range = ColorRange::where('id',$pal)->firstOrFail();
                    $markingColor = "#" . mixRange(substr($range->start_hex,1));
                }

                $markings[$marking->name] = $markingColor;
            }
        }
    }

我想我可以用很多复杂的if语句来完成这个,但它对我来说似乎不是一个优雅的解决方案.此外,还有一个例外:’渐变’,一个全身标记,即使它是一个全身标记,也会在所有内容下面.到目前为止,它是唯一具有此类异常的标记.

我尝试过使用PHP提供的各种排序功能,但我没有太多运气. uksort似乎是最有希望的,但是因为我们排序的值存在于数据库中而不是数组中我们正在排序(imagick函数必须被提供一个标记=>颜色数组格式),它证明很难使用.

Tl; dr:我需要根据数据库中存在的键(标记区域)中存在的不确定数据量对数组进行重新排序.实现这一目标最优雅的方法是什么?

以下是对代码的一些优化,内联的注释用于描述所执行的操作.这显然没有完成,因为Marcin在他的回答中指出了一些更好的东西.
// Determine number of markings
    $num = mt_rand(1,10);

    // Removed redundent $num > X as the conditions were already meet that it was > X by the prevIoUs if statement
    if ($num == 1) {
        $markingNum = 0;
    } else if ($num < 4) {
        $markingNum = 1;
    } else if ($num < 6) {
        $markingNum = 2;
    } else if ($num < 8) {
        $markingNum = 3;
    } else if ($num < 10) {
        $markingNum = 4;
    } else {
        $markingNum = 5;
    }

    // Calculate Marking type and color
    $markings = array();

    if ($markingNum > 0) {
        for ($m = 1 ; $m <= $markingNum; $m++) { // incrimented to 1 and <= so we can dynamically select elements
            // Set color values (pulls from the "pallet" selected earlier in the code,which will determine the range of color that marking can be)
            $pal = $pallet->{'marking' . $m}; // Removed if/else and replaced with a dynamic variable


            // Uncommon marking (10% chance)
            $r = mt_rand(1,10);

            // removed duplicate database selections for a simple $rarity variable that accomplishes the same task
            if ($r == 10) {
                $rarity = 1;
            } else {
                $rarity = 0;
            }

            $marking = DataMarking::where('rarity',$rarity)
                                  ->where('public',1)
                                  ->whereNotIn('name',array_keys($markings))
                                  ->whereNotIn('region',$regions)
                                  ->orderByRaw("RAND()")
                                  ->first();

            // Colors marking
            if ($pal == 0) {
                $markingColor = rand_color();
            } else {
                $range = ColorRange::where('id',$pal)->firstOrFail();
                $markingColor = "#" . mixRange(substr($range->start_hex,1));
            }

            $markings[$marking->name] = $marking; // adds all of the marking data,this is where you could have a z-index in the database
            $markings[$marking->name] = $markingColor; // add your color to your marking data
            $regions[] = $marking->region;

        }
    }
