to return an html result in loop in a function to a different page

I have a class

class files{

  function displayhtml(){?> 

select name="df">

for($i=0;$i<10;$i++){?>

         <option value="<?php echo "$i"; ?开发者_如何学运维>"><?php echo "$i"; ?></option><?php
        }?></select><?php
  }
}
?>

I have a file newgetfile.php, i need to display this drop down in newgetfile.php by calling this function in newgetfile.php

You need to use the html part as string.

function displayhtml(){ 

$string  = '<select name="df">';

for($i=0;$i<10;$i++){?>

         $string .= '<option value="' . $i .'">' . $i . '</option>';

  }

$string .= '</select>';
return $string;
}

class files
{

    public static function displayhtml() { 

        $string  = '<select name="df">';

        for($i = 0; $i < 10; $i++) {
            $string .= '<option value="' . $i .'">' . $i . '</option>';
        }

        $strin .= '</select>';

        return $string;
    }
}


echo files::displayhtml();

You can take all drop down code in one php variable and can return it to where you want to display it..
