#Buffering

Buffering allows you to capture printed or echoed data instead of outputting it right away.

#Basic Buffer

To start buffering use the startBuffer() method. Then, to stop the buffer and get the captured output use the getCurrent() method.

echo 'First ';
$buffer = tr_buffer()->startBuffer();
echo 'Middle';
$middle = $buffer->getCurrent();
echo 'Last ';
echo $middle;

Will output,

Top Last Middle

#Buffer Indexing

You can also index output to save chunks with the indexBuffer() method. You can then access the indexed buffer with the getBuffer() method.

$buffer = tr_buffer();

$buffer->startBuffer();
echo '<li>One</li>';
$buffer->indexBuffer('one');

$buffer->startBuffer();
echo '<p>Two</p>';
$buffer->indexBuffer('two');

echo '<ul>';
echo $buffer->getBuffer('one');
echo '</ul>';

echo $buffer->getBuffer('two');

Will output,

<ul><li>One</li></ul><p>Two</p>
