I've got a PHP script that simply e-mails me a test message. If I go into my webserver cPanel I can create a cronjob that runs the script every 10 minutes and it works perfectly.
I manually schedule the cron job in cPanel using the following settings:
10 * * * * php -q /home1/user1/public_html/mail.php
Again the above works fine, but when I try to create the cron job via PHP instead of cPanel it never runs. When I check the cPanel to see if the job was actually created by my php script it DOES show up. All the settings that show up in cPanel are correct, it just doesn't run the script.
This is the PHP code I'm using to create the cron job:
$output = shell_exec('crontab -l');
file_put_contents('/tmp/crontab.txt', $output.'10 * * * * php -q /home1/user1/public_html/mail.php'.PHP_EOL);
echo exec('crontab /tmp/crontab.txt');
I imagine it could be a permission issue or something like that? Not really sure why the job works when I create it, but doesn't when PHP creates it.
PHP shell scripts, e.g. cli/cron jobs, STILL require a <?php tag. e.g.
#!/usr/bin/php
<?php
$output = blah blah blah
Remember that there's no such thing as a "php script". There's only files that have PHP code blocks within them. Without an opening <?php tag block SOMEWHERE in the file, the PHP execution engine will never kick in, even though the file will have been processed/parsed by PHP.
Without <?php, the file's contents will simply be treated as plaintext output.
Ended up figuring this out...I'm sure what was wrong with the php code I was using above but it seems that was somehow causing the execution failure.
I'm now using the code below and the job schedules and actually runs :)
exec('echo -e "`crontab -l`\n10 * * * * php -q /home1/user1/public_html/mail.php" | crontab -');

As implied in the title, the Cron Job is supposed to execute a php file (update.php, to be specific). The php file then writes to a csv file stored in the same directory.
I have the time set to * * * * * so that it executes every minute. The command is written as follows:
php -q /home//public_html/wallboard/update.php
I don't believe this is causing any errors, though it also doesn't seem to write to the CSV file. When I visit update.php in a browser, however, it executes and writes to the CSV file immediately. I'm not experienced with Cron Jobs and I'm sure there's an issue, but I don't know what exactly that issue is. Let me know if you have suggestions/questions. Any help is appreciated!
Current Command:
* * * * * usr/bin/php -q /home/<user>/public_html/wallboard/update.php
update.php:
<?php
include('lib/HelpDeskView.php');
include('lib/WallboardDisplay.php');
include('helpdesk.csv');
$helpdesk = new HelpDeskView();
$text="\r\ntest,test,test";
file_put_contents( "helpdesk.csv" , $text, FILE_APPEND);
Since your script resides in your public_html directory you can use wget for your Cron Job
wget -O - -q https://yoursite.com/wallboard/update.php
-O - output is written to the standard output in this case it will go to the email address you specify in CPanel
-q quiet mode
IMHO the best way is to contact support and ask them about command line syntax.
This is how I'm doing it at my linux server using cPanel.
This runs script.php which is stored in public root. Course, replace <username> in command line with your username.
At another server I'm using same command line with /usr/bin/php instead of php at the beginning of line, but I'm aware that not all servers use same command line. Some require php-cli in command line instead of php, some don't "like" -f argument, etc. So try various combinations.

Important thing: When trying different commands wait at least a minute (this case) to see if it works because Cron doesn't fire your script immediately.
Try to execute the same command in PHP CLI and check if it gives you any error, you might be missing some libraries or references required for CLI execution.
/usr/bin/php -d register_argc_argv=On /home/USERNAME/public_html/DOMAIN/artisan AMIR:HOME
as part of a php-slim web application, in my init.php file I require a Crontab.php which contains the following code:
<?php
// clears any existing crontab jobs first
exec("crontab -r");
$ctCommand = '"*/1 * * * * php ./ProcessCycleTimeData.php"';
exec("(crontab -l 2>/dev/null; echo " . $ctCommand . " ) | crontab -");
exec("crontab -l");
?>
When I run the commands manually, the job gets added and I can see it being recorded, however it doesn't seem to run. However, when I run php ./ProcessCycleTimeData.php it works fine. Any ideas where to troubleshoot this?
I'm looking into the error logs, and every minute I get the following log:
crontab: no crontab for daemon
You can use crontab -e to edit the crontab, this will open your default editor (generally vi if other is not set).
Edit the crontab for the user you need this script to run, and add a line as:
*/1 * * * * php ./ProcessCycleTimeData.php
This means
Every one minute
Note:
The PHP snippet you provide is trying to edit the crontab and add the above line. However it might be failing due lack of permission.
I managed to get it working. My solution was to check if the crontab was actually running by appending the crontab job with >>/tmp/auto-update.log 2>&1 which allowed me to further investigate the issue.
I found that the crontab was indeed running, but as a different user (hence why when I was manually calling crontab -e I could not see the job since I am calling it as my own username.
The crontab was also actually invoking my PHP script, where I could then find out the errors in the auto-update.log, which happened to be due to incorrectly stating the require paths.
I have a php script, let's say fetch.php which will pull data from other database and insert those data to another database, How do I run the script automatically maybe via command line, let's say I want it to run Everyday at 3pm? Something like a cron.
Here is the cron rule you should add:
00 15 * * * php fetch.php
Read more here: Running a script every day using a cron job
If you are on Windows, you can make use of Windows Task Scheduler.
Here is the link: http://windows.microsoft.com/en-US/windows/schedule-task#1TC=windows-7
Using php from command line is not that hard. Start the fetch.php file like this:
#!/usr/bin/env php
<?php
// You have the command line arguments available as
$scriptName = $argv[0];
$firstArg = $argv[1];
// Add PHP code here :)
// If an error occurs, exit the script with an error code:
if($someError) exit(1);
After saving, set execution rights:
$ chmod 755 fetch.php
Then add the script to the crontab. There are many ways, control panels like Plesk and cPanel have a web interface for example, but here's the command line version:
$ crontab -e
Add to the file:
0 15 * * * /path/to/fetch.php
Save, and you're done.
I have a cron that's set to run every ten minutes that works fine if I execute the file manually by entering
php register.php
But, my cron will not execute this file once it includes anything cURL related. My cron is as follows
*/10 * * * * /usr/bin/php /var/www/html/register.php
I know that the cron is getting the correct file because at the very top of it, I put php's mail function to send me an email so that I know it was executed. But, anything cURL related will not execute. There aren't any global variables or server variables in the script, so that isn't the reason. I've checked both the crontab and the php error logs and nothing is there pertaining to this issue.
Try to add this at the beginning of your script:
chdir(dirname(__FILE__));
I've set up a cron job to run. It executes a php file which is named cronj.php
But it doesn't work and cron job notification I get is:
/root/website/myworld/blabla/cronj.php: line 1: ?php: No such file or directory
And line 1 in that file is simply a php tag <?php I don't know how
Cron is executing the file as if it was a shell script. Normally you would put in a shebang line (like #!/usr/bin/env php) at the top of the file so that the shell knows how to invoke it, but PHP doesn't like it - as it outputs everything outside its tags. Thus, instead of this:
0 3 * * * /mypath/myscript.php ...
try this:
0 3 * * * /usr/bin/env php /mypath/myscript.php ...
or use #Ravenex's trick.
EDIT I was just rightly admonished for assuming PHP behaves in a consistent way. Apparently, shebang does work in PHP. My apologies to #chess007.
We use cron to run nightly tasks in a php facebook game. We do it by using curl like this:
/usr/bin/curl http://www.ourdomain.com/page.php
If I remember right we had some issues using localhost to try to avoid external lookups. Also we tried using php command line execution, which mostly worked but caused a few strange bugs.
Try to call the web url (http://.....).
It's apparently not parsing it as an PHP script.
Edit:
Please show use the cronjob you used, to verify my hunch was right.
Use this to set your cron and also give email address in your cron setting Cpanel so that you get an email when cron runs successfully
wget -O - http://YOURSITE/cron.php
