I don't know how to call this.
if I wrote a php script to calculate an interest for saving account.
how can I tell the program to run the script on the end of the day without user monitoring. such as 0.00am or the server start.
If you are on UNIX server, Cron is the way to go. On Windows machine use Scheduled tasks.
Call the PHP file via CLI using Crontab, if you're on Windows try pyCron.
you need to run cron jobs look wiki cron for more information. hope this helps.

I am pretty new to PHP but I want to crate a website uptime checker which should email me whenever my websites are down.
This means that the script should run non stop. Can this be done in PHP? How?
No. You want to run a script at a set interval instead. Cron is what you want.
Here's a tutorial to get started. http://net.tutsplus.com/tutorials/php/managing-cron-jobs-with-php-2/
You could use a cron task to schedule your script running at regular intervals. Or if you are hosting on Windows use the Windows Scheduler.
Normally there's an execution time limit that will stop scripts from running longer than a specified time. A better solution would be to set up a cron job that executes the script periodically.
you can do it by a cron job (a script to check your website) and make it run at regular intervals.
I need to run a php script at the scheduled time daily to update some fields in database and to send automated email. How I can do this?
Is it possible to write some service in XAMP server to run the script daily at scheduled time? I have no idea how to update database and send email automatically at the scheduled time. Can any one share some ideas or concepts?
I am using PHP and MySQL running in Linux Server.
You should use a Cron job to do it. Check out the examples on the Wikipedia page.
The Cron Job should call a script using the php executable that runs the necessary task.
Just create the script that does the required job, test it by hitting the URL in your browser once you are sure it works right. Copy the URL and add a Cronjob
Then schedule this command to run at whatever time you want to run
php ABSOLUTE_URL_TO_SCRIPT >> logfile
The log file is optional. But it will give you a chance to see what happened.
For example if you want to run your script every 4 hours, and assuming your script is at http://localhost/work/scripty.php and assuming that your http root is /var/www,
you would run "crontab -e" in terminal and add the following line:
* */4 * * * php /var/www/work/scripty.php
If you need more information just comment I will update the answer.
PHP cannot run script by itself,since php doesn't have daemons like python !!
So you have to take OS help to invoke your custom script .
For example in linux :
(example.sh)
export USE_PHP=php
cd $SCRIPT_ROOTDIR
$USE_PHP -f cronfile.php service="checkdatabase"
(service is the parameter passed to your cronfile).
For setting up cron jobs ,have a look at this link
http://www.cyberciti.biz/faq/how-do-i-add-jobs-to-cron-under-linux-or-unix-oses/
In Linux, We can create .sh file and can give a specific time to run that is called cron job.
SO should use this method just make a shell file and give a time period to it.
You should take a help with linux expert for that.
Use the following: Cron Job
I am in need of something like this I need a script to run independently each day at a certain time without fail, the script will be for PDO mysql and some other things,
Can anyone point me in the right direction??
Thanks
If PHP is configured to run from the commandline you can simply setup either a cronjob (crontab -e) (Linux) or a scheduled task (Windows) where you run the php file(s) you want to run.
php -f /path/to/script.php
If you're on Linux, use a CRON Job. For Windows, use a Scheduled Task.
There are also services that do this online. A quick Google search returns this site.
Can anyone help
I need to run a php file or function on a specific time (atmost predifined).
So i can not find any way to do this , i think about server variable.
This has to be done without browser i mean there is no chance that browser run at that time it may be or may not. I hope you understand the problem pls give solution Thanks.
You need to use cron (on *nix) or scheduled tasks (windows)
http://en.wikipedia.org/wiki/Cron
Most web host software (such as cPanel) allows you to edit the crontab (the list of scheduled tasks) via the web interface
they are called cron jobs
Run a code after specific time in php
I have written a PHP script which generates an SQL file containing all tables in my database.
What I want to do is execute this script daily or every n days. I have read about cron jobs but I am using Windows. How can I automate the script execution on the server?
You'll need to add a scheduled task to call the URL.
First of all, read up here:
MS KB - this is for Windows XP.
Second, you'll need some way to call the URL - i'd recommend using something like wget - this way you can call the URL and save the output to a file, so you can see what the debug output is. You can get hold of wget on this page.
Final step is, as Gabriel says, write a batch file to tie all this up, then away you go.
e: wget is pretty simple to use, but if you have any issues, leave a comment and I'll help out.
ee: thinking about it, you don't even really need a batch file, and could just call wget directly..
add a scheduled task to request the url. either using a batch file or a script file (WSH).
http://blog.netnerds.net/2007/01/vbscript-download-and-save-a-binary-file/
this script will allow you to download binary data from a web source. Modify it to work for you particular case. This vbs file can either be run directly or executed from within a script. Alternately you do not have to save the file using the script, you can just output the contents (WScript.Echo objXMLHTTP.ResponseBody) and utilize the CMD out to file argument:
cscript download.vbs > logfile.log
save that bad boy in a .bat file somewhere useful and call it in the scheduler: http://lifehacker.com/153089/hack-attack-using-windows-scheduled-tasks
Cron is not always available on many hosting accounts.
But try this:
http://www.phpjobscheduler.co.uk/
its free, has a useful interface so you can see all the scheduled tasks and will run on any host that provides php and mysql.
You can use ATrigger scheduling service. A PHP library is also available to create scheduled tasks without overhead. Reporting, Analytics, Error Handling and more benefits.
Disclaimer: I was among the ATrigger team. It's a freeware and I have not any commercial purpose.
Windows doesn't have cron, but it does come with the 'at' command. It's not as flexible as cron, but it will allow you to schedule arbitrary tasks for execution from the command line.
Yes, You can schedule and execute your php script on windows to run automatically. In linux like os u will have cron but on windows u can schedule task using task scheduler.
If your code is in remote hosted server then create a cron-job for the same.
Else if in local then use a scheduled task in windows.Its easy to implement.I am having servers with so many scheduled tasks running.
