When you pass your argument, the $x is the current var (outside the scope of your function), probably you got a notice for undefined variable.

You should do a str_replace of a placeholder

klmn("<input type='button'  value='\$x'>"); // note the backslash \$x

function klmn($st){   
    echo "<table>";
    for ($x=1; $x<=12; $x++) 
    {
        echo "<td>".str_replace('$x',$x,$st) ." </td>";
    }
    echo "</table>";
}
