Description: ------------ I have to run the sample code and error. "create" function is "$this->api" using. Scope Resolution Operator (::) is not available Correct sample $tinyurl = new Services_TinyURL(); $url = $tinyurl->create('http://www.joestump.net'); Test script: --------------- <?php require_once 'Services/TinyURL.php'; try { $url = Services_TinyURL::create('http://www.joestump.net'); echo $url; } catch (Services_TinyURL_Exception $e) { echo $e->getMessage(); } ?> Expected result: ---------------- display http://tinyurl.com/2c3gzr Actual result: -------------- Fatal error: Using $this when not in object context in /usr/local/lib/php//Services/TinyURL.php on line 92

The proper way is to instantiate the class: try { $tiny = new Services_TinyURL(); $url = $tiny->create('http://www.joestump.net'); echo $url . "\n"; } catch (Services_TinyURL_Exception $e) { echo $e->getMessage(); } That being said, I did fix the documentation in my comments. Sorry about that. It changed during the submission process per PEAR group comments.
