Question

我有下面的数组，我似乎无法弄清楚如何从阵列Team_1中提取信息并回显出其中的0 - 5值。

 array (size=3)
      'Team_1' => 
        array (size=5)
          0 => string '1199' (length=4)
          1 => string '1182' (length=4)
          2 => string '1105' (length=4)
          3 => string '1212' (length=4)
          4 => string '891' (length=3)
      'Team_2' => 
        array (size=5)
          0 => string '' (length=0)
          1 => string '' (length=0)
          2 => string '' (length=0)
          3 => string '' (length=0)
          4 => string '' (length=0)
      'Team_3' => 
        array (size=5)
          0 => string '' (length=0)
          1 => string '' (length=0)
          2 => string '' (length=0)
          3 => string '' (length=0)
          4 => string '' (length=0)

Answer 1

键是Team_1，因此您可以直接引用它并执行foreach循环来执行回显（您可以添加任何要回显的html以格式化值）。

foreach ($arr['Team_1'] as $val) {
    echo $val.'<br>';
}

如果您的目的是遍历所有团队并回显值

foreach ($teams as $team => $vals) {
    echo $team;
    foreach ($vals as $val) {
        echo $val;
    }
}

Answer 2

$output1 = $array['Team_1'][0]; // Should output 1199
echo $output1;


OR

foreach ($array['Team_1'] as $data){
 echo $data.'<br/>';
}

从阵列中拉出阵列
