Zend_Cache_Frontend_Output is an output-capturing frontend.
It utilizes output buffering in PHP to capture everything
between its start() and end()
methods.
This frontend doesn't have any specific options other than those of
Zend_Cache_Core.
An example is given in the manual at the very beginning. Here it is with minor changes:
<?php
// if it is a cache miss, output buffering is triggered
if (!($cache->start('mypage'))) {
// output everything as usual
echo 'Hello world! ';
echo 'This is cached ('.time().') ';
$cache->end(); // output buffering ends
}
echo 'This is never cached ('.time().').';
Using this form it is fairly easy to set up output caching in your already working project with little or no code refactoring.
