explode function does not work on a string in PHP

The echo $line_of_text; gives me "test1 test2 test1 test2 " But once I use the explode by ' ' it only divides the string by 2 parts. as a result it says pieces[0] = test1test1 and pieces[1]=test2test2. I need it to be divided into 4. Thanks in regards.

UPDATE: I found the problem. The function seemed to be in a foreach loop. It ran twice. I found out about it when I ran echo $pieces[0].'<br>';. It gave me:
Test1 test2
Test1 test2

After some fixing I got it to work as I intended. Thanks for the quick responses. 

    public function load_time_period()
{
    $file_handle = fopen($GLOBALS['configfile_time_periods'], "r+");

    $i = -1;
    while (!feof($file_handle)) {

        $line_of_text = fgets($file_handle);

        switch ($line_of_text) {

            case stripos($line_of_text, "define timeperiod") > -1:
                if (stripos($line_of_text, "define timeperiod") > -1) {
                    $i++;
                    $obj_time_periods[$i] = new nagmon_time_period();
                }
                break;

            case stripos($line_of_text, "timeperiod_name") > -1:
                $obj_time_periods[$i]->set_timeperiod_name(trim(str_replace("#", "", str_replace("timeperiod_name", "", $line_of_text))));
                break;

            case stripos($line_of_text, "alias") > -1:
                $obj_time_periods[$i]->set_alias(trim(str_replace("#", "", str_replace("alias", "", $line_of_text))));
                break;

            case stripos($line_of_text, "weekday") > -1:
                $obj_time_periods[$i]->set_weekday(trim(str_replace("#", "", str_replace("[weekday]", "", $line_of_text))));
                break;

            case stripos($line_of_text, "exception") > -1:
                $obj_time_periods[$i]->set_exception(trim(str_replace("#", "", str_replace("[exception]", "", $line_of_text))));
                break;
            case stripos($line_of_text, "exclude") > -1:
                $obj_time_periods[$i]->set_exclude(trim(str_replace("#", "", str_replace("exclude", "", $line_of_text))));
                break;

            case stripos($line_of_text, " ") > -1:



                echo htmlentities($line_of_text);



                $obj_time_periods[$i]->set_variable_command($pieces[0]);
                $obj_time_periods[$i]->set_variable_value($pieces[1]);
                break;

            default:
                break;
        }
    }
    fclose($file_handle);
    return $obj_time_periods;


}

Use this to explode by any space or tab or by more spaces or tabs:

$pieces = preg_split('/\s+/u', trim($line_of_text));
print_r($pieces);
//Array ( [0] => test1 [1] => test2 [2] => test1 [3] => test2 )

I'm pretty sure the error is happening before. Can you share more of your code? When I try this

$line_of_text = "test1 test2 test1 test2 ";

$pieces = explode(' ', $line_of_text);
var_dump($pieces);

It gives me the output 

array(5) {
  [0]=>
  string(5) "test1"
  [1]=>
  string(5) "test2"
  [2]=>
  string(5) "test1"
  [3]=>
  string(5) "test2"
  [4]=>
  string(0) ""
}

which is correct.

You can try out small snippets like this in an online interpreter, for example here: http://sandbox.onlinephpfunctions.com/
