Description: ------------ The example script docs/examples/dispatcher.php uses emit() with an array of signal parameters (line 27). The signal parameter is fetched by Logger:log(). log() just prints the parameter. Because the signal parameter is passed as array and packed in another array as parameter for log(). But log() just expects a flat array. So implode() produces a Notice and the output is just Array / signal message. To make it short: remote the array() call from line 27. Test script: --------------- See dispatcher.php: class Logger { public function log() { $args = func_get_args(); echo 'Log: ' . implode(' / ', $args) . "\n"; } } class Downloader { public function download($file) { .. for ($nA = 0; $nA < 100; $nA += 10) { $dp->emit('download-progress', array($file, $nA)); } ... } } Expected result: ---------------- No Notice schould be thrown, correct log message output. Log: http://some.where/over/the/rainbow.htm / begin download Beginning download Log: http://some.where/over/the/rainbow.htm / 0 / progress Log: http://some.where/over/the/rainbow.htm / 10 / progress Log: http://some.where/over/the/rainbow.htm / 20 / progress Log: http://some.where/over/the/rainbow.htm / 30 / progress Log: http://some.where/over/the/rainbow.htm / 40 / progress Log: http://some.where/over/the/rainbow.htm / 50 / progress Log: http://some.where/over/the/rainbow.htm / 60 / progress Log: http://some.where/over/the/rainbow.htm / 70 / progress Log: http://some.where/over/the/rainbow.htm / 80 / progress Log: http://some.where/over/the/rainbow.htm / 90 / progress Log: http://some.where/over/the/rainbow.htm / download complete Actual result: -------------- Log: http://some.where/over/the/rainbow.htm / begin download Beginning download PHP Notice: Array to string conversion in C:\PHP5.2.3\dispatcher.php on line 16 Notice: Array to string conversion in C:\PHP5.2.3\dispatcher.php on line 16 Log: Array / progress PHP Notice: Array to string conversion in C:\PHP5.2.3\dispatcher.php on line 16 ....

That's because I changed the emit() api and didn't update the example. Bad me.

Thank you for your bug report. This issue has been fixed in the latest released version of the package, which you can download at http://pear.php.net/get/Event_SignalEmitter
