Explode to array and print each element as list item

Question

I have a set of numbers in a table field in database, the numbers are separated by comma ','. I am trying to do the following:

Step 1. : SELECT set of numbers from database and explode it to array :

$array =  explode(',', $set_of_numbers);

Step 2. : Print each element of the array as list item by using foreach loop :

foreach ($array as $list_item => $set_of_numbers){
    echo "<li>";
    print_r(array_list_items($set_of_numbers));
    echo "</li>";}

Please anybody tell me what is wrong. Thank you.

Assuming your original $set_of_numbers is simply a CSV string, something like 1,2,3,4,..., then your foreach is "mostly" ok. But your variable naming is quite bonkers, and your print-r() call uncesary:

$array = explode(',', $set_of_numbers);
foreach($array as $key => $value) {
   echo "<li>$key: $value</li>";
}

Assuming that 1,2,3,4... string, you'd get

<li>0: 1</li>
<li>1: 2</li>
<li>2: 3</li>
etc...

$numbers = "1,2,3";

$array =  explode(",", $numbers);

/* count length of array */
$arrlength = count($array);

/* using for while */
$x = 0; 

while ($x < $arrlength) {

  echo "<li>$array[$x]</li>" . PHP_EOL;
  $x++;

}
echo PHP_EOL;

/* using for classic */
for ($x = 0; $x < $arrlength; $x++) {

  echo "<li>$array[$x]</li>" .  PHP_EOL;

}
echo PHP_EOL;    

/* using for each assoc */
foreach ($array as $value) {

  echo "<li>$value</li>" .  PHP_EOL;

}
echo PHP_EOL;    

/* using for each assoc key */
foreach ($array as $key => $value) {

  echo "<li>$key => $value</li>" .  PHP_EOL;

}

You actually don't need to explode on the commas. You can just replace each comma with an ending tag followed by an opening tag and then wrap your whole string in an opening and closing tag.

$set_of_numbers = '1,2,3';
echo '<li>' . str_replace(',', '</li><li>', $set_of_numbers) . '</li>';
// outputs: <li>1</li><li>2</li><li>3</li>

No looping is necessary.

This can easily be achieved by the following code snippet:

<?php
$my_numbers = '1,12,3.2,853.3,4545,221';
echo '<ul>';
foreach(explode(',', $my_numbers) AS $my_number){
    echo '<li>'.$my_number.'</li>';
}
echo '</ul>';

The above code will output the following HTML:

<ul><li>1</li><li>12</li><li>3.2</li><li>853.3</li><li>4545</li><li>221</li></ul>
