When you explode, and there is no delimiter you have requested, the result at index 0 is the entire string.

 test
//    [1] =>  test2.
//    [2] =>  test3
//    [3] =>  test4
//)

$string = "test test2. test3 test4";
print_r( explode(',', $string) );
//Array
//(
//    [0] => test test2. test3 test4
//)
