Re: How to get rid off empty elements of an array?

2006/8/7, afan@afan.net <afan@afan.net>:

Hi to all! I have a form with 6 text fields where visitor has to enter product serial number (same type data). he has to enter AT LEAST ONE. for ($i=0; $i<6; $i++) {

    echo '<input type="text" name="PSN['.$i.']" value="'.$PSN[$i].'"

size="25">'; } After the form is submitted I'm getting an array Array (

    [0] => abc123
    [1] => ddd111
    [2] => poi987
    [3] =>
    [4] =>
    [5] =>

) Now, I need to get rid off empty elements of the array, to get this: Array (

    [0] => abc123
    [1] => ddd111
    [2] => poi987

) To do that I tried: foreach ($PSN as $value) {

   if (!empty($value))    $PSN_New[] = $value;

} but every time I'm getting one additional element of the array: I tried foreach ($PSN as $value) {

   if ($value != '')    $PSN_New[] = $value;

} too - same result. Array (

    [0] => abc123
    [1] => ddd111
    [2] => poi987
    [3] =>

) No space or anything else is "entered" in 4th field. What I'm doing wrong? Thanks for any help. -afan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php There are probably some whitespaces in the elements which refuse to be

deleted. Also consider using array_filter() instead of looping through the array (used without a callback function filter all elements which evaluate to boolean false).
