Pseudo code looks like this:, _(*7)

```php, _(*8)

$playlists = [...many playlists to check...]; $failed_reports = [];, _(*9)

// for each given playlist - make checking $output = []; $return_code = 0; exec('vendor/bin/hls-monitor playlists '.implode(",",$playlists), $output, $return_code);, _(*10)

if($return_code) { // there were problems with this palylist $failed_reports[] = $output; }, _(*11)

// then report if anything is not good if(count($failed_reports)) { // mail reports to somewhere }, _(*12)

```, _(*13)
