I'm kinda stuck with the following:

I have on my form a regular text field where the user is supposed to enter values (numbers) separated by spaces.

When processing the form, I try to both extract the values and count the number of values user has given, like this:

$numberofvalues=sizeof(explode(" ", trim($inputfield)));

Everything works OK, if the user input is in correct format (e.g. "1 2 3"), and the trim() takes care of leading and trailing spaces, but the problems arise if the user input contains more than one spaces between the values, like "1 2 3".
All of a sudden the array generated by explode() has 4 elements instead of 3.

How can I circumvent this?

    Well, one solution would be;

    $new = array();
    foreach (explode(' ', $inputfield) AS $key => $val) {
    if ($val != '') $new[] = $val;

    }

    This would place the values from $inputfield into a new array, $new. Hope it helps.

      Another would be

      $numberofvalues=sizeof(preg_split("/[ ]+/", trim($inputfield)));

      The [] are optional - they're there only so you can see the space 🙂
