PHP：将数组值添加到 <option>

Question

我正在寻找创建方法

 <option>.Name1.</option>
<option>.OtherName.</option>

对于每个最高值，有理由思考如何提取数组值，而不知道名称（Name1、OtherName 等，这些值将是动态的）。对于 print_r 或 var_dump，您将看到以下结构：

array (
  'Name1' => 
  array (
    'diametru' => 
    array (
      0 => 15,
      7 => 16,
    ),
    'latime' => 
    array (
      0 => 6,
      9 => 5,
    ),   
  ),
  'OtherName' => 
  array (
    'diametru' => 
    array (
      0 => 16,
      2 => 17     
    ),
    'latime' => 
    array (
      0 => 6,
      1 => 7,
      10 => 5,
      35 => 8,
    ),   
  ),
.........
)

如果您能提供任何帮助，我将不胜感激。

Answer 1

你可以只使用 Foearch :

<select>
<?php 
 foreach($array as $keyname=> $list)
{

echo '<option value="'.$keyname.'">'.$keyname.'</option>'; 
}
 ?>
</select>

Answer 2

你有很多方法可以做到：

$var = [
  'Name1' => [
    'diametru' => [
      0 => 15,
      7 => 16,
    ],
    'latime' => [
      0 => 6,
      9 => 5,
    ],   
  ],
  'OtherName' => [
    'diametru' => [
      0 => 16,
      2 => 17     
    ],
    'latime' => [
      0 => 6,
      1 => 7,
      10 => 5,
      35 => 8,
    ],   
  ]
];

foreach ($var as $index => $value) {
    echo "<option>$index</option>";
}

foreach (array_keys($var) as $index) {
    echo "<option>$index</option>";
}

Answer 3

使用array_keys

$array = [
    'Name1' => [
        'diametru' => [7,6]
    ],
    'othername' => []
];
$output = array_keys($array);
$option = '';
foreach ($output as $val) {
    $option .= "<option>$val</option>";
}
print_r($option);
