So you have a PHP script you want to execute on a regular basis. Although you could run it manually, it would be much easier if you could do it automatically. You can do this with cron on Mac and Linux, and with Task Scheduler on Windows.
This is one of the VERY few tutorial videos that is a pleasure to watch and isn't annoying. well done
Great turtorial, explains the subject at a good and clear speed.
Run in 1.25 speed and this is perfect.
thanks for the tip
True
Hani San 0.03 speed is better
Thanks
thanks lol
Straight to the point. Very informative and easy to follow.
Simple and to the point. Excellent tutorial. Thanks a lot
Well presented, clear and concise. The graphics in the first half help allot.
Perfect!!!! thanks a lot! clear, visual and lots of resources.
One thing to be aware of is that in early versions on UNIX (pre system V, I think), all 5 fields were anded. So in your first example, it would only have fired on 21st August if it happened to be a Friday. I think all Linux versions use the modern interpretation. It's rare that you'd want to specify both day of month and day of week, but it's probably a good idea to avoid.
Ah ok, good to know, thanks!
@@dave-hollingworth It's pretty rare that you want to have both day of month and day of week on the same job anyway, but if you do, just be very careful that it's behaving the way you expect.
Also in your example you said "21st August and every Friday". I presume you meant "every Friday in August".
This is very very nice video, top, but with wrong title. The tutorial is not about php, but cron job.
Thus i wanted to know about cron jobs, how it works and i never had opportunity to hear about that, it met my knowledge wish, despite of wrong title, where i something others expected. Thank you.
Subscribed ! what an explanation! Well done !!!
Thank you! :-)
Fantastic explanation, thanks!
is this the standard to execute for example a record generator on mysql? and if I want to upload my web in a hosting, Do I have to use their resources to schedule in the same way?
This is the standard for executing a scheduled task, yes, although there are other ways (web-based schedulers etc.) Each host has their own way to run scheduled tasks, check with them to see what they offer
@@dave-hollingworth thanks Dave it was very useful your help!
Hello !
First, thanks for this tutorial.
I have a situation that I wonder if it's good to use cron tasks. I have my website logo which is an image and in my database there is a table with global information about the website including a field "url_logo_website" that has " christmas_logo.png" as value. I was wondering if we can, every Christmas/Easter/Halloween/Etc season, change this field. I have no problem about doing the php+sql script, I'm just wondering... Do you think I would have to make a single task for every event I want to change my logo's url ? Also will I have to make many separated scripts for each event?
I have my website that has a MVC structure. Can I give the cron task a route going all the way to my controller so it will execute a php function inside my class? (The goal would be to be able to have a controller dedicated to all methods related to cron tasks).
Also... (Sorry for all those questions) do you think we can control cron tasks from an admin dashboard inside the website?
Hi John - yes, all these things are possible.
For changing your logo based on the date, there are several ways to do it. You could have several cron jobs, one for Christmas, one for Easter and so on - but every time you added an event, you'd need a new cron job. It doesn't sound like the job will take long to run (replacing an image for example), so I would run one job, on a regular basis, say once a day. This would check to see if there is an upcoming event, and act accordingly. This way you only need to have the check in the script that it runs, and you can change events in the database and know that the next time the script runs, it will be aware of the database changes.
As for executing a method inside an app with an MVC structure - methods inside controller classes tend to rely on the framework having loaded lots of code beforehand, e.g. in the front controller, bootstrap code, etc. Just loading a class file and running a method might not work. Instead though, you can just use something like cURL on the command line to request the URL directly. For example, if you have a controller method available at example.com/tasks/run, then you can just run this from cron with curl example.com/tasks/run.
And for controlling cron tasks from within the website, yes of course, but you'd need to develop an interface to store them, run cron etc. from your code.

Is there a video about how to add a SQL file run like like that? I need to run an SQL Update every 15 minutes to clearing pending alerts.
MySQL does have an event scheduler: dev.mysql.com/doc/refman/5.7/en/event-scheduler.html
Alternatively, you could just run the SQL from a PHP script.
Thank you Dave for the explanation. It is very easy to understand for a beginner like me. May I know if i want to implement this for my bidding system. For example, to send out emails to highest bidder after the countdown timer ends. Can I do that? Thank you in advance!
Yes of course, you can put anything you like in the script that is run automatically, so in your example you could have a script that calculated who to send the email to, connecting to a database, sending an email and so on.
@@dave-hollingworthGreat! Thank you sir😁
Thank you so much.
Hello Dave Hollingworth Channel,
Thanks so much for your lession, it is very good and work for me
But I want to know if task scheduler can execute another function beside insert query?
For example: I want to export report as xlsx file everyday at 5:00 PM, Could I do that?
Thanks in advance and hope to get your response soon.
The task scheduler can run any script you like - so if you have a script that exports reports as you say, you can schedule this in the same way with no problems. Every day at 5pm would be 0 17 * * * in cron.
For Mac and linux cron is used for windows??

Hi Dave, Can I run the script on a webpage? I want to learn how to create a script that will input my email address in a field and click submit once a day for x days. Cheers!
Cron is for running a script on a server on a regular basis. You could have a PHP script that does that, but you're probably better off using something like cURL (more info and an example here: davidwalsh.name/curl-post-file)
Dave Hollingworth thank you sir
I need to do some scheduler manually since cron limited to one minutes only , + some projects I need to add/edit sheduler manually

does the hello php.php file contain the script you want to send with a cron?
"php hello.php" is the command you want cron to execute, so yes, hello.php would contain the script. You can run PHP scripts on the command line by prefixing them with "php".
apologies for basic question.. it took me a while to realise the cron would actually trigger the code on the php page... i am used to using 'action' in my forms to run the php code.
No problem, happy to help!
How about 1 time scheduled jobs. How can I specify a one time job.

Which command line xampp,cmd or phpstorm terminal im doing it locally?
Whichever gives you access to run commands in a terminal window, for example in Windows, the Command Prompt app (cmd)
@@dave-hollingworth i tried above but all says command not recognized why?
@@faizannabi7540 Maybe you don't have cron installed - what is your operating system? It's installed by default on Mac and Linux, I'm not sure about Windows
@@dave-hollingworth im on win 10 may be its not installed.

it is possibel to send 1 mail on every 40seconds to different email ids???
Yes, if you write a script to do so. You can set up cron to run every 40 seconds no problem. Your script would have to read from a database of email addresses, or keep track of which email was next and so on.
you have any example or any video tutorial for this topic??
I'm afraid not, sorry
Hey jadeja, have u done this script?

What exactly is your problem?
Hi Aaron,
thank you for your interest! I'll answer your questions below:
1. The course isn't really about mass emailing, rather exactly how to send emails using PHP code. You can of course write code that will send mass emails (e.g. newsletters), but you need to write the PHP application to do that. The course will teach you how to send emails to multiple recipients, how to add formatting and so on, so these could be used to write a mass-mailing application. If you're already using aweber and you don't want to create your own PHP application, then the course might not be useful for you.
2. It's very easy to contact me if you need help, I'm there in Udemy to answer questions. I always reply within 24 hours, usually less than that. Happy to help with any questions at all that are related to the course.
3. Yes, you could do that, write code that sent 150 emails an hour using PHPMailer and your hosting provider's SMTP server, that would work. Alternatively you could use your existing host with a different SMTP server provider, or a non-SMTP solution like Mailgun (that I go through on the course) that allow you to send 10,000 emails for free before you get charged.
4. I'm a big fan of Mailgun so that's the one I recommend.
You might be interested in something like MailChimp - might be worth taking a look to see if that is useful for you before you take the course (I'm certainly not trying to dissuade you from taking my course, but I don't want you to take it if it's not going to be useful for you!).
There's also a 30-day money back guarantee on the course, so if you take it and don't like it, then you can get a refund.
I hope that helps, if you have any more questions please don't hesitate to ask!
Cheers,
Dave
