[PHP]Variablename in string ausgeben

[sniper_w]

Code:

<?

   function myLoadFileInString($filename)
   {
        $res = "";

        if (!file_exists($filename))
          return $res;

        $lines = file($filename);
        foreach ($lines as $line_num => $line)
        {
            $res = $res . $line;
        }
        return $res;
   };
   
   $var1 = 'hahah';

   $test = myLoadFileInString( 'test.htm' );
   
   $test = str_replace( '$var1', $var1, $test );
   
   echo "$test";
?>

Code:

  <tr>
    <td><div align="center">$var1</div></td>
    <td><div align="center">$var2</div></td>

    <td><div align="center">$var3</div></td>
    <td><div align="center"></div></td>
  </tr>

Jetzt will, dass es automatisch ersezt wird, die Variable $var1, ohne dass ich den VariablenName kenne. -> $test = do_replace( $var1, $test);
