Install ------- [](#install) Install with Composer: ``` $ composer require garethellis/crontab-schedule-generator ``` Usage ----- [](#usage) I wrote this library for use with [Jobby](https://github.com/jobbyphp/jobby), but it could be used in any situation where you need to output a Crontab schedule with PHP. I recommend using the included functions for expressive code. ### Hourly [](#hourly) The `Hourly` class can be used to output crontab schedules to be run on an hourly basis. The `hourly()` function can be used to create a new instance of `Hourly`. If you call `hourly()` by itself, you'll get a crontab schedule of "run hourly on the hour". You can specify the minutes past the hour to run at by using the `at()` method. This method takes either a numeric string (0-59) or one of the following text strings: `on the hour`, `quarter past`, `half past` or `quarter to`. You can use the `repeatingAt` method to run a task multiple times in an hour. This method takes the same argument as `at()`, i.e. a numeric string (0-59) or a text string from the above list. ``` use function Garethellis\CrontabScheduleGenerator\hourly; echo hourly(); //outputs "0 * * * *" (i.e. run hourly on the hour) echo hourly()->at("20"); //outputs "20 * * * *" (i.e. run hourly at twenty past the hour) echo hourly()->at("half past"); //outputs "30 * * * *" (i.e. run hourly at half past the hour) echo hourly()->at("on the hour")->repeatingAt("quarter past")->repeatingAt("half past")->repeatingAt("quarter to"); //outputs "0,15,30,45 * * * *" (i.e. run every 15 minutes) ``` ### Daily [](#daily) The `Daily` class can be used to output crontab schedules to be run on a daily basis. The `daily()` function returns a new instance of `Daily`. If you call `daily()` by itself, you will get a crontab schedule of "run daily at midnight". You can specify a time to run using the `at()` method. This method takes a (string) time in 24 hour format as its only argument (e.g. `"16:00"`). There is also the `repeatingAt()` method if you would like to schedule a task to run multiple times in a day. This method takes a whole number (numeric string) as its only argument; this number represents the hour to repeat the job at. Note, this will create a schedule which repeats at the same number of minutes past the hour as whatever you specify using the `at()` method. It's not possible (currently) to do something like "run at 9:30, then repeat at 11:15, then repeat at "13:40". ``` use function Garethellis\CrontabScheduleGenerator\daily; echo daily(); //outputs "0 0 * * *" (i.e. run daily at midnight) echo daily()->at("4"); //outputs "0 4 * * *" (i.e. run daily at 4am) echo daily()->at("15:25"); //outputs "25 15 * * *" (i.e. run daily at 3:25pm / 15:25) echo daily()->at("9:30")->repeatingAt("10")->repeatingAt("11"); //outputs "30 9,10,11 * * *" (i.e. run daily at 9:30, 10:30 and 11:30) ``` ### Weekly [](#weekly) The `Weekly` class can be used to output crontab schedules to be run on a daily basis. The `weekly()` function returns a new instance of `Weekly`. If you call `weekly()` by itself, you will get a crontab schedule for midnight Sunday. You can specify a day to run on using the `on()` method. This method takes a day name in English (e.g. 'Sunday') as its only argument. If you call it like this, you will get a crontab schedule set to run on that given day at midnight. You can specify a time to run in the same way as the `Daily` class - see above. You can also set weekly schedules to repeat on given days using the `repeatingOn()` method, passing in a day name. ``` use function Garethellis\CrontabScheduleGenerator\weekly; echo weekly(); //outputs "0 0 * * 0" echo weekly()->on("Friday"); //outputs "0 0 * * 4" (i.e. run every Friday at midnight) echo weekly()->on("Saturday")->at("12:10"); //outputs "10 12 * * 6" (i.e. run every Saturday at 12:10pm echo weekly()->on("Saturday")->repeatingOn("Sunday"); //outputs "0 0 * * 0,6" (i.e. run every Saturday & Sunday at midnight) ``` ### Monthly [](#monthly) The `Monthly` class allows you to output crontab schedules to be run on a monthly basis. The `monthly()` function returns a new instance of `Monthly`. Calling `monthly()` by itself will give you a crontab schedule for midnight on the first of the month. To specify a day to run on, you can use an ordinal or whole number (as a numeric string) with the `on()` method. You can also use the `at()` method in the same way as with weekly & daily. ``` use function Garethellis\CrontabScheduleGenerator\monthly; echo monthly(); //outputs "0 0 1 * *" echo monthly()->on("4th"); //outputs "0 0 4 * *" (i.e. run every month on the 4th at midnight) echo monthly()->on("12th")->at("10:15"); //outputs "15 10 12 * *" (i.e. run every month on the 12th at 10:15am) ``` ### Every X minutes/Every X hours [](#every-x-minutesevery-x-hours) The `Interval` class allows you to output crontab schedules to be run every X minutes or every X hours. This class can be instantiated using the factory function `every()`. Unlike the other classes in this library, this class is no good on its own, i.e. `every("5")` will not output anything. Instead, you have to use the `minutes()` and `hours()`methods to create instances of `MinutesInterval` and `HoursInterval` respectively. From here, usage of these classes is very similar to the above. With `HoursInterval` you can specify a start and stop time using the `from()` and `until()` methods. For `MinutesInterval`, the interval value must be a divisor of 60 as a numeric string (i.e. 1,2,3,4,5,6,10,12,15,20,30,60). ``` use function Garethellis\CrontabScheduleGenerator\every` echo every("5")->minutes(); //outputs "*/5 * * * *" (i.e. run every 5 minutes) echo every("2")->hours(); //outputs "0 */2 * * *" (i.e. run every 2 hours on the hour) echo every("3")->hours()->at("half past"); //outputs "30 */3 * * *" (i.e. run every 3 hours at half past the hour) echo every("2")->hours()->from("8")->until("14"); //outputs "0 8,10,12,14 * * *" (i.e. run on the hour at 8am, 10am, 12pm and 2pm) ``` Change log ---------- [](#change-log) Please see [CHANGELOG](CHANGELOG.md) for more information what has changed recently.
