Deprecated: Function split() is deprecated

Code:

  
  $name = "abc,def,ghi,jkl";

  $nameArray = split("\,", $name);
  
  echo count($nameArray);
  
  for($i=0;$i";
  }
  $name = "abc,def,ghi,jkl";

  $nameArray = preg_split("/,/", $name);//  split to preg_split and \, to changed /,/
  
  echo count($nameArray);
  
  for($i=0;$i";
  }

Solved:

  
   $name = "abc,def,ghi,jkl";

  $nameArray = preg_split("/,/", $name);//  split to preg_split and \, to changed /,/
  
  echo count($nameArray);
  
  for($i=0;$i";
  }
