How to create a scheduler application in php

Question

I want to develop a scheduler in php I know there is cronjob already present in php but I want to develop like java but I don't want to use sleep(1) method. I know how to develop it in JAVA. JAVA code is given below.

scheduler = schedulerFactory.getScheduler();
            JobDetail job = JobBuilder.newJob(GenerateJob.class).build();

            SimpleTrigger simpletrigger = (SimpleTrigger) TriggerBuilder.newTrigger().startAt(startTime)
                    .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                            .withIntervalInHours(Integer.parseInt(Constants.INTERVAL_HOUR)).repeatForever())
                    .build();

            scheduler.scheduleJob(job, simpletrigger);
            scheduler.start();

AND

public class GenerateJob implements Job {

     // Operation will be placed here

}

Is it possible to develop like above in php? If not then is there any way to develop scheduler. Help me with code. Thanks in advance.

You can try this Quartz. Here are some examples as well. Its similar implementation for the scheduler in PHP as you are looking for.

I have tried but huge no of error occurring. Because of limited character I cannot paste error. – ankur pramanik Nov 20 '19 at 11:57
Is there any alternative of ```$store = new YadmStore(new SimpleStoreResource($config));``` to create jobstore? – ankur pramanik Nov 23 '19 at 05:49

In my case, I need to run scripts every 1, 5 and 30 seconds but independent of platform (must work either on Windows and Linux platforms) with same source code. So I made the following, which is executing in about 15 microseconds every second. Very quick !

// init priorities array in seconds
$schedules = [
    'high'  => 1,
    'medium'=> 5,
    'low'   => 30
];

while($now ??= time()) {
    foreach($schedules as $priority => $seconds)  {
        if($now >= $next[$priority] ??= $now) {
            $next[$priority] += $seconds;
            
            // --> execute your script here for every priority
            // in my case I call high.php, medium.php and low.php with 
            // with execInBackground() by TheUO available here : 
            // https://stackoverflow.com/a/12117258/2282880;
            
            // something like execInBackground("scripts/", "$priority.php");
        }
    }
    time_sleep_until(++$now);
}

working since PHP 7.4 (especially for ??=)

Hope it could help some of you.
