Cron scheduled tasks are tasks that execute planned work at the agreed time. This is what it means on the surface. In Linux, we often use cron server to complete this work. The cron server can perform specific tasks according to the time specified in the configuration file.
<?php
namespace Cron;
abstract class AbstractField implements FieldInterface
{
protected $fullRange = [];
protected $literals = [];
protected $rangeStart;
protected $rangeEnd;
public function __construct()
{
$this->fullRange = range($this->rangeStart, $this->rangeEnd);
}
public function isSatisfied($dateValue, $value)
{
if ($this->isIncrementsOfRanges($value)) {
return $this->isInIncrementsOfRanges($dateValue, $value);
} elseif ($this->isRange($value)) {
return $this->isInRange($dateValue, $value);
}
return $value == '*' || $dateValue == $value;
