How to count number of an elements of an array and run a loop for that number?

I am trying to insert multiple name in guestname input field. So i've declared guestname as an array. After inserting some name in guestname field using separated by comma ( e.g : superman, batman, spiderman ) i get output as "guestname":["superman, batman, spiderman "]. I want to run loop counting all the values of the array and print one by one where others data (e.g email and address) will remain same.

<input type="text" name="guestname[]" multiple>
<input type="text" name="email">
<input type="text" name="address">
<tr>
foreach(array_count_values($_POST['guestname'] as $key => $value)
{
  echo "<td>". $value."</td>";
  echo "<td>". $_POST["email"]."</td>";
  echo "<td>". $_POST["address"]."</td>";
}

</tr>

First you have to expload comma seprated value and then read it from data.

$guest = explode(",", $_POST['guestname'][0]);
foreach($guest as $value)
{
  echo "<td>". $value."</td>";
  echo "<td>". $_POST["email"]."</td>";
  echo "<td>". $_POST["address"]."</td>";
}

Hope you are looking something like below:

<form method="post">
 <input type="text" name="guestname">
 <input type="text" name="email">
 <input type="text" name="address">
 <input type="submit" value="submit">
</form>

<?php
 if(isset($_POST['guestname'])){
   echo "<table border='1'>";
   foreach(array_filter(explode(',',$_POST['guestname'])) as $key => $value)
   {
     echo "<tr><td>". $value."</td>";
     echo "<td>". $_POST["email"]."</td>";
     echo "<td>". $_POST["address"]."</td></tr>";
   }
 echo "</table>";
}

?>

foreach(explode(',', join(',', $_POST['guestname'])) as $key => $value)
{
    ...
}

It's what you are loking for?

It merge all $_POST['guestname'] values into a string adding additional , and then re-explode them in array and loop in.

Example:

$_POST['guestname'][] = "name1, name2, name3, name4";
$_POST['guestname'][] = "name5, name6, name7";

return:

name1
name2
name3
name4
name5
name6
name7

Code "guestname":["superman, batman, spiderman "] means that "superman, batman, spiderman " is a string. If these were an array it would be "superman", "batman", "spiderman ". So maybe you can use explode to get an array of elements. For example

$guestname = explode("," , $_POST['guestname']);

And then

foreach(array_count_values($guestname as $key => $value)
