Question

我有一个教师名单，其中包含以下属性：

teacher 1 skills = English, Math
teacher 1 gender = Male

teacher 2 skills = Spanish, Math, Law
teacher 1 gender =  sex = Female

teacher 3 skills = English, Geography
teacher 3 gender = Male

首先，我想告诉我们有多少英语（和其他任何事情）的老师，因为技能可以是多种多样的，我所做的就是检查数组中的副本并计算它：

     $stack = array();
     $blogusers = get_users( 'orderby=nicename&role=author' );
  foreach ( $blogusers as $user ) {
     $myUsers = $user->user_description (this is the skill list);
     $mystrings = strtolower($user->user_description);
     $descTokens = explode(',', $mystrings);
     $descTokens = array_map('trim',$descTokens);
     $stack = array_merge($stack, $descTokens);
  }
     $count_values = array();
     foreach ($stack as $a) {
       @$count_values[$a]++;
     }
     $total_duplicates = 0;
     foreach ($count_values as $a) {
       if($count_values[$a]<=1){
          unset($count_values[$a]);
       } else{
          $total_duplicates += $count_values[$a];
       }
      }

然后这样做

    <ul class="margin-top-20">
      <?php
        foreach ($count_values as $key=>$count ) {
          echo '<li>'.$count.' di <strong>'.$key.'</li>';
        }
      ?>
    </ul>

这是正确的，输出是正确的：

2 English teachers
2 Math teachers
1 Spanish
1 Law
1 Geography

但我也有性别，所以理想情况下我想拥有

2 English teachers, 1 male, 1 male
2 Math teachers, 1 male, 1 female
1 Spanish, 1 female
1 Law, 1 female
1 Geography, 1 male

我尝试添加：

      $sex = array();
      $user_sex = get_user_meta( $the_user_id, $gender, $single ); 
      array_push($sex, $user_sex);
      foreach($descTokens as $lang){
        $userSex[$lang] += $user_sex;  
      }
      foreach ($count_values as $key=>$count ) {
        echo '<li>'.$count.' di <strong>'.$key.' gender '. $userSex[$key] .'</li>';
      }

但那不对。

Fullcode我正在尝试：

  <?php
    $stack = array();
    $userID = array();
    $nPost = array();
    $listmaterie = array();
    $materie = array();
    $gender = 'sesso';
    $single = true;
    $sex = array();
    $blogusers = get_users( 'orderby=nicename&role=author' );
    $userSex = array();
    foreach ( $blogusers as $user ) {
        $myUsers = $user->user_description;
        $mystrings = strtolower($user->user_description);
        $descTokens = explode(',', $mystrings);
        $descTokens = array_map('trim',$descTokens);
        $stack = array_merge($stack, $descTokens);
        $the_user_id = $user->ID;
        $numPosts = count_user_posts( $the_user_id );
        array_push($userID, $the_user_id);
        array_push($nPost, $numPosts);
        $user_sex = get_user_meta( $the_user_id, $gender, $single ); 
        array_push($sex, $user_sex);
        foreach($descTokens as $lang){
          $userSex[$lang] += $user_sex;  
        }
     }
       // get the count for each language by counting the duplicate strings;
     $count_values = array();
     foreach ($stack as $a) {
       @$count_values[$a]++;
     }
     $total_duplicates = 0;
     foreach ($count_values as $a) {
       if($count_values[$a]<=1){
          unset($count_values[$a]);
       } else{
          $total_duplicates += $count_values[$a];
       }
      }
     $count_sex = array();
     foreach ($sex as $b) {
       @$count_sex[$b]++;
     }
     $total_duplicates_sex = 0;
     foreach ($count_sex as $b) {
       if($count_sex[$b]<=1){
          unset($count_sex[$b]);
       } else{
          $total_duplicates_sex += $count_sex[$b];
       }
      }
    ?>

转储 我有3个用户

var_dump($stack);

array（11）{[0] =＆gt; string（8）＆＃34; francese＆＃34; [1] =＆GT; string（7）＆＃34; chimica＆＃34; [2] =＆GT; string（6）＆＃34; fisica＆＃34; [3] =＆GT; string（7）＆＃34; scienze＆＃34; [4] =＆GT; string（7）＆＃34; inglese＆＃34; [5] =＆GT; string（6）＆＃34; fisica＆＃34; [6] =＆GT; string（7）＆＃34; chimica＆＃34; [7] =＆GT;串（8）＆＃34; spagnolo＆＃34; [8] =＆GT; string（8）＆＃34; francese＆＃34; [9] =＆GT; string（6）＆＃34; fisica＆＃34; [10] =＆GT; string（8）＆＃34; italiano＆＃34; }

var_dump($sex);

array（3）{[0] =＆gt; string（7）＆＃34; maschio＆＃34; [1] =＆GT; string（7）＆＃34; maschio＆＃34; [2] =＆GT; string（7）＆＃34; femmina＆＃34; }

Answer 1

代码：

foreach($blogusers as $user){
    foreach(explode(', ',$user->user_description) as $skill){  //"comma then space" delimited
        $result[$skill][]=get_user_meta($user->ID,'sesso','true');  // push user's gender into subject's array
    }
}

foreach($result as $subject=>$gender_array){
    echo "<div>",sizeof($gender_array)," $subject teachers";
    $count_genders=array_count_values($gender_array);  // avoids php NOTICE @ array_walk
    array_walk($count_genders,function($v,$k){echo ", $v $k",($v!=1?"s":"");});
    echo "</div>";
}

考虑到您的示例输入数据，我的方法将输出：

2 English teachers, 2 Males
2 Math teachers, 1 Male, 1 Female
1 Spanish teachers, 1 Female
1 Law teachers, 1 Female
1 Geography teachers, 1 Male

如何添加关联数组？
