我正在尝试创建一个数组，从循环浏览wordpress中的帖子，构建一系列人物，他们玩过的游戏以及他们每场比赛发布的分数。
我目前的代码：
$world_rank = [];
while ( $the_query->have_posts() ) : $the_query->the_post();
$category = get_the_category();
$cat_name = $category[0]->cat_name;
$score = get_field('score');
$author = get_the_author();
$array_size = sizeof($world_rank[$author]['games']);
if( $array_size < 1 ){
$world_rank[$author]['games'][] = ['name' => addslashes($cat_name), 'scores' => [$score] ];
}else{
// loop through the array and see if they have been similar game names if so, add them to push array
$i = 0;
foreach($world_rank[$author]['games'] as $game){
if($game['name'] == $cat_name){
echo 'Same name ' .$game['scores']. ' score is '.$score.'</br>';
array_push($game['scores'], $score);
// this doesn't seem to work
// break;
}
else if($game['name'] !== $cat_name && $i == $array_size - 1 ){ //
// if the names are not the same create a new array for the other game
$world_rank[$author]['games'][] = ['name' => addslashes($cat_name), 'scores' => [$score] ];
}
$i++;
}
}
endwhile;
上面的输出给出了这个：
$world_rank = array (
'frantheman' =>
array (
'games' =>
array (
0 =>
array (
'name' => 'Candy',
'scores' =>
array (
0 => '23',
),
),
1 =>
array (
'name' => 'PopCorn',
'scores' =>
array (
0 => '25',
),
),
2 =>
array (
'name' => 'Chocolate',
'scores' =>
array (
0 => '5',
),
),
3 =>
array (
'name' => 'Candy',
'scores' =>
array (
0 => '25',
),
),
)
);
我怎样才能让world_rank数组拥有＆＃39; Candy＆＃39;由于＆＃39; Candy＆＃39;值在数组中出现两次，并结合“糖果”的分数。键。所以现在看起来像：
$world_rank = array (
'frantheman' =>
array (
'games' =>
array (
0 =>
array (
'name' => 'Candy',
'scores' =>
array (
0 => '23',
1 => '25'
),
),
1 =>
array (
'name' => 'PopCorn',
'scores' =>
array (
0 => '25',
),
),
2 =>
array (
'name' => 'Chocolate',
'scores' =>
array (
0 => '5',
),
)
);
正如您所看到的，在新阵列中，“糖果”＃39;有2个阵列的分数。任何有关这方面的帮助将不胜感激。感谢。

您的代码中存在一个小错误。如果你想在foreach中修改$ game，你需要通过引用来遍历它。只是做你的foreach：
foreach($world_rank[$author]['games'] as &$game){
然后，您实际修改了实际得分数组，并且不创建本地副本。 （如果您想了解更多相关内容，请撰写Google PHP副本。）
您还需要break语句，否则您将在循环结束条件中创建另一个元素。但是你已经把它放在了正确的地方;不予评论。

这是我的代码段的WP实现：
$user_game_stats=[]; // this will be the final output array containing all statistics
while($the_query->have_posts()){
$the_query->the_post();
$game = addslashes(get_the_category()[0]->cat_name);
$user = get_the_author();
$score=intval(get_field('score'));
$user_game_stats[$user][$game]['scores'][]=$score;
if(!isset($user_game_stats[$user][$game]['high_score']) || $score>$user_game_stats[$user][$game]['high_score']){
$user_game_stats[$user][$game]['high_score']=$score;
$user_high_scores_by_game[$game][$user]=$score; // this is a temporary array for calculating rank
}
}
// a second loop is essential because the rank calculations involve the users' high scores and player count per game
foreach($user_high_scores_by_game as $game=>$user_scores){
$total_game_users=count($user_scores);
arsort($user_scores); // sort the users by their high score in DESC order and preserve the keys (usernames)
$ordered_users=array_keys($user_scores); // high scores are no longer required, we just want to determine rank
foreach($ordered_users as $number=>$user){
$user_game_stats[$user][$game]['rank']=++$number; // starts from zero so $number is modified/increased by one for human-friendly rank
$user_game_stats[$user][$game]['efficiency']=$number / ($total_game_users * .1); // I don't like "efficiency" but can't offer a better term
// you may want to introduce rounding on the efficiency calculation
}
}
var_export($user_game_stats);
