Display multidimensional array as unordered list using keys and values

Question

So I have array like this one.

[
    '0020098238 - Address 1' => [
        '20011045 - 1',
        '20011880 - 2',
        '20014727 - 3',
        '20015506 - 4'
    ],
    '0020011189 - Address 2' => [
        '20012490 - 11',
        '20018679 - 22',
        '20023569 - 33',
        '20028843 - 44'
    ],
    '0020102015 - Address 3' => [
        '20008315 - 55',
        '20008689 - 66',
        '20021267 - 77',
        '20032518 - 88'
    ]
]

Now, I want to make foreach or implode or something else and as result get list like this one

0020098238 - Address 1
- 20011045 - 1
- 20011880 - 2
- 20014727 - 3
- 20015506 - 4
0020011189 - Address 2
- 20012490 - 11
- 20018679 - 22
- 20023569 - 33
- 20028843 - 44
0020102015 - Address 3
- 20008315 - 55
- 20008689 - 66
- 20021267 - 77
- 20032518 - 88

I have tried with foreach($array as $key => $val) and than implode $val but it doesnt work propper. I can collect keys but values from array missing.

Thx

Here is what I have tried (nested foreach)

foreach ($user_sap_data as $customer => $destinations) {
    echo '<ul>';
        echo '<li>' . $customer . '</li>';
        foreach ($destinations as $destination) {
            echo '<li>' . $destination . '</li>';
        }
    echo '</ul>';
}

but as result I am getting only key of first foreach (in nested foreach)

It is not the same question like PHP nested array into HTML list because in other question there are key => (key => val, key => val...) but in this example is key => (val, val, val) etc. its similair but not duplicated

In nested foreach, you have approached, but misplaced your opening ul tag. Check this answer — Thamilhan

Try with this solution. In second foreach you have to get key as value...

echo '<ul>';
foreach ($user_sap_data as $key => $value) {
 echo '<li>' . $key . '</li>';
 echo '<ul>';
  foreach ($value as $subkey => $subvalue) {
   echo '<li>' . $subkey . '</li>';
  }
 echo '</ul>';
}
echo '</ul>';

i think with implode doesnt work, but I didnt try :)

echo "<ul>";
foreach($arr as $key=>$values){
    echo "<li>$key</li>"; //print array key
    echo "<ul>";
    foreach($values as $val){ 
         echo "<li>$val</li>"; // print subarray values
    }
    echo "</ul>";
}
echo "</ul>";

Your Code - updated:

    echo '<ul>';
    foreach ($user_sap_data as $customer => $destinations) {
          echo '<li>' . $customer . '</li>';
          echo '<ul>';
          foreach ($destinations as $destination) {
            echo '<li>' . $destination . '</li>';
          }
          echo '</ul>';
        }
        echo '</ul>';

You can achieve this with two foreach loops one within another. First loop will iterate through Parent level elements, and second will iterate through child within it.

<?php
$array = array(
  '0020098238 - Address 1' => array(
    '20011045 - 1',
    '20011880 - 2',
    '20014727 - 3',
    '20015506 - 4'
  ),
  '0020011189 - Address 2' => array(
    '20012490 - 11',
    '20018679 - 22',
    '20023569 - 33',
    '20028843 - 44'
  ),
  '0020102015 - Address 3' => array(
    '20008315 - 55',
    '20008689 - 66',
    '20021267 - 77',
    '20032518 - 88'
  )
);
?>
<ul>
  <?php
  foreach ($array as $key => $val) {
    ?>
    <li>
      <?php echo $key; ?>
      <ul>
        <?php
        foreach ($val as $key_ch => $val_ch) {
          ?>
          <li>
            <?php echo $val_ch; ?>
          </li>  
          <?php
        }
        ?>
      </ul>
    </li>
    <?php
  }
  ?>
</ul>

Since you approached with implode, you can use like this:

echo "<ul>";
foreach ($arr as $key => $value) {
    echo "<li>$key";
    echo "<ul><li>" . implode("</li><li>", $value) . "</li></ul></li>";
}
echo "</ul>";

With two foreach nested:

echo "<ul>";
foreach ($arr as $key => $value) {
    echo "<li>$key";
    echo "<ul>";
    foreach ($value as $subvalue) {
        echo "<li>$subvalue</li>";
    }
    echo "</ul></li>";
}
echo "</ul>";
