Hello!

Tell me, please, how can I check the array for empty values?

For example,

$test = array('');

If the values ​​of the array will contain a different number of spaces, then how to check and exclude keys with empty values?

Thank!

Well, you can array_filter($array) call the function array_filter($array) without a callback function and it will clear the array of null,false,''

    like this

      foreach ($playerlist as $key => $value) { if (empty($value)) { //проверяем если пустой unset($playerlist[$key]); } }

    if the whole array is empty

     if (empty($playerlist)) { //empty array }

      The array_filter function can help

       array_filter($test, 'remove_empty'); function remove_empty($v) { return trim($v) == $v; }
