  • Your class doesn't have a function called check(). Commented Jan 2, 2021 at 13:06

  • @ADyson Array ( [0] => 2 [1] => 3 [2] => 5 ) Notice: Trying to access array offset on value of type null in /home/u483428433/domains/ytsubme.com/public_html/ ...on line 8 Commented Jan 2, 2021 at 13:08
  • Ok thanks. Your one() method doesn't have a return statement. You need return $lol; at the end of it. Commented Jan 2, 2021 at 13:08

Thanks to @ADyson, i had to return from the function instead of echo.

<?php
class BioTool{
public function one(){
    print_r($lol);
return $lol =[2,3,5]; 

}
 public function two(){
     $newarr=$this->one();
    print_r($newarr[0]); // working
}
}

$biotool=new BioTool();
$biotool->two();
