[](#interpolatephp---)

A small PHP package for interpolating values from an array into a template string.

Think of it as a lightweight alternative to [Mustache](https://github.com/bobthecow/mustache.php):

```
use yuanqing\Interpolate\Interpolate;

$i = new Interpolate;
$tmpl = '{{ foo.bar }}, {{ foo.baz }}!';
$data = array(
  'foo' => array(
    'bar' => 'Hello',
    'baz' => 'World'
  )
);
$i->render($tmpl, $data); #=> 'Hello, World!'
```

Usage
-----

[](#usage)

1. Tags are enclosed in double braces.
2. Straight-up substitution; there are no conditional blocks, sections and so forth.
3. Tags can reference nested values in the multidimensional array (as in the example above).
4. A value to be interpolated can be a [scalar](http://php.net/manual/en/function.is-scalar.php), an object that implements `__toString()`, or a callback that returns a string:

    ```
    $i = new Interpolate;
    $tmpl = '{{ baz }}';
    $data = array(
      'foo' => 'Hello',
      'bar' => 'World',
      'baz' => function($data) {
        return sprintf('%s, %s!', $data['foo'], $data['bar']);
      }
    );
    $i->render($tmpl, $data); #=> 'Hello, World!'
    ```

    Note that the first argument of the callback is the `$data` array.
5. If a value for a tag is not found, the tag will be replaced with an empty string.

The two examples in this README may be found in [the examples.php file](https://github.com/yuanqing/interpolate/blob/master/examples.php).
