Example usage

Use-Case: When deploying an application update the crontab depending on the release version (this can for exmaple be called from within a capistrano deploy script)

php update-crontab.php $FROM_RELEASE $TO_RELEASE $APP_NAME $APP_ENV $APP_PATH

update-crontab.php:

define('DS', DIRECTORY_SEPARATOR);

if ($argc != 6) {
        
    die("wrong call");
}

$fromRelease = (integer)$argv[1];
$toRelease = (integer)$argv[2];
$projectName = $argv[3];
$stage = $argv[4];
$projectPath = $argv[5];

// composer-based autoloading, could also include the required files yourself etc.
require($projectPath . DS .'vendor'. DS . 'autoload.php');

use PHPCron\Cron;

// create signatures used to identify the jobs for the application, stage and release version
$fromSignature = 'app='. $projectName .'; env='. $stage .'; rel='. $fromRelease;
$toSignature = 'app='. $projectName .'; env='. $stage .'; rel='. $toRelease;

$crontab = new Cron\Tab;
$jobs = $crontab->get();
foreach ($jobs as $index => $job) {
            
    $jobSignature = $job->getComment();
    if ($jobSignature == $fromSignature || $jobSignature == $toSignature) {
        
        // remove all jobs for the last and current release
        $crontab->remove($index);
    }
}

if (0 !== $toRelease) {

	$jobs = array();
	$job = new Cron\Job;
	$job->setMinute('*/10');
	$job->setCommand('php script/something.php'); // $projectPath-relative calls
	$jobs[] = $job;

	$job = new Cron\Job;
	$job->setMinute('0');
	$job->setHour('23');
	$job->setCommand('./script/something-else.sh');
	$jobs[] = $job;

    foreach ($jobs as $job) {
                      
        $originalCommand = $job->getCommand();
        $finalCommand = 'cd '. $projectPath .' && export APPLICATION_ENV="'. $stage .'" && '. $originalCommand;
        $job->setCommand($finalCommand);                       
        $job->setComment($toSignature);
        $crontab->add($job);
    }
}
