add template function

[lloydzhou]

i have one template function only 132 chars:

function t($t,$d='data'){return "extract(\$$d);".str_replace(['{{','}}','{%','%}'],['");$c(',');$c("','");','$c("'],'%}'.$t.'{%');}

there's some example code here:

• define template file "test.tpl"

      <h1>{{$title}}</h1>
      {% foreach($messages as $message){ %}
          <p>{{$message}}</p>
      {% } %}

• define the data will render to template

    $data = [
        'title' => 'test title',
        'messages' => ['message1', 'message2', 'message3']
    ];
    $c='print_r';

• compile template and save into file

file_put_contents('test.php', '<?php '. t(file_get_contents('test.tpl')));
include ('test.php');

• compile the template into function, can call it by using render data

$f = create_function('$d,$c', $t = t(file_get_contents('test.tpl'), 'd'));
$f($data, 'print_r');
