Print a string in a loop php

Question

I am building a table in which i should put some values inside the <td></td>.

What I have is a $checked value which I convert it in some string like: id1,id2,id3

What I need to do is a loop which permits me to print this values like this. Something like this:

(for i=0, i<length of words, i++) {
echo "<td> .id[i].</td>"
}

My real variable is this:

 if(isset($_POST['Submit'])) {
    echo "<pre>";
    $checked = implode(',', $_POST['checkbox']);
    echo $checked;

Thanks!

What are you having trouble with?

If $_POST['checkbox'] is already an array then you don't have to implode() it before processing :

foreach ($_POST['checkbox'] as $id) {
    echo '<td>' . $id . '</td>';
}

Note that this will fail and issue a warning if $_POST['checkbox'] is not an array (very possible).

One question please, i see better now, i need to print only the checkbox values, but how can i limit it to print me just 4 values, i mean if the checkbox is an array and has 4 values, it should print me 4..
