README

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

Think of it as a lightweight alternative to Mustache:

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

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, 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.

Requirements

Interpolate.php requires at least PHP 5.3, or HHVM.
