使用foreach

foreach是一个用于循环迭代的关键字。

当需要显示数组中的多个值时使用。

$members = [
  'name' => '鈴木',
  'height' => 172,
  'hobby' => '野球'
];
foreach($members as $member){
  echo $member;
}

$members = [
  'name' => '鈴木',
  'height' => 172,
  'hobby' => '野球'
];
//キーとバリューそれぞれ表示
foreach($members as $member => $value){
  echo $member . 'は' . $value;
}

$members_1 = [
  '鈴木' => [
    'height' => 172,
    'hobby' => '野球'
  ],
  '田中' => [
    'height' => 168,
    'hobby' => '野球'
  ]
];
}

在这种情况下会怎样呢？

foreach($members_1 as $member){
  echo $member;
}

//多段階の配列を展開
foreach($members_1 as $member_1){
  foreach($member_1 as $member){
    echo $member;
  }
}
