Cronjob is not working on Ubuntu 16.04 - php

I would like to put in place some cronjobs for my website.
My actual cronjob is:
4 * * * * /usr/bin/php /var/www/domain/backup.php
But it doesn't work.
Mannually the cron job is working.
With a service like https://www.easycron.com it's working too.
In Terminal, when I make crontab -e, I see my cronjob but it does not seem to run.
From where I can start my search to understand ?
Thanks.

In my server, when setting up a php file to run, I only have to put:
4 * * * * php /var/www/domain/backup.php. They run flawlessly. Works the same for my shell scripts as well with just bash /directory/thisScript.sh
I added this as an answer because my reputation score won't let me add comments yet.

Crontab process to link a php file

i have a php file named "name.php which i want to run in every 5 minutes. I want to use crontab for this function. I have found a lot of tutorial but those all are really confusing to me. Everyone seems to use a crontab file and write like so ...
*/5 * * * * wget http://www.domainname.com/cronfile.php
but i really did not get it. Suppose i have a domain name "www.mydomain.com", so if i create a php file name.php how it be directed by www.mydomain.com/name.php.
Can anyone describe shortly how i should run my php file using crontab or wget.
i am running my project in symfony.
(I'd comment if I had enough reputation to clarify if you are running the file locally - but I think that you are.)
Here's now I do it:
*/5 * * * * /usr/bin/php /home/user/cronfile.php

Running PHP script from cron

I am trying to run a PHP script through a cronjob. I already did this hundred of times, but now it's not working and I cannot figure out why.
I created a script called update_db.php in /var/www/html/ When I run the script by hand:
php /var/www/html/update_db.php
everything works fine. When I put this into a cronjob, it does nothing. My cronjob:
* * * * * /usr/bin/php /var/www/html/update_db.php
I tried to put a bash script in front of it that calls the PHP script, but, again, it only works when calling by hand, not from a cron.
There are no errors in the syslog. Also no mail in /var/mail. I restarted cron already, but no effect.
I use ubuntu 14.04.
Can anyone help me?
Is * * * * * php /var/www/html/update_db.php not working? You shouldn't need to use /usr/bin/php.
Also, check to make sure crons are running on your current system and that your files/directories have the appropriate permissions to be run by the cron.
CRON "should" be logging.
Check the /var/log/cron, looking for your script errorrs or otherwise.
some implementations of cron need a full on restart - I have personanlly never had this issue, but I know fellow admins who have spent far too much time chasing fault, when a simple restart did the trick.

Run a php script with cron in mac

I am trying to run in mac a php script using cron. I want this php script to run every one minute. I read several sources online and from my understanding is better if I use launchd. In any case, I try to make it work with cron and then if it works fine I might try to use launchd.
So here is what I do:
I wrote this command in a txt file:
* * * * * /usr/bin/php /Applications/MAMP/htdocs/php_test/main_script.php
There I have the path to php (I found it with the "which php" command) and the path to my php script.
I named the txt file: crontasks.txt and I run it through terminal with this command:
crontab /Users/dkar/Desktop/crontasks.txt
When I list the crons (crontab -l) I see that this job is listed. But nothing comes as output every one minute. The output is supposed to be an image stored in a specified folder. What am I missing here?
Thanks in advance

You might have a slight miscomprehension how crond processes the "crontab" files. It would suffice to run the command crontab -e, which would let you edit your personal crontab or you edit the system crontab.
If you use crontab -e it will open the default editor (vi/vim) and you can enter the line:
* * * * * /usr/bin/php /Applications/MAMP/htdocs/php_test/main_script.php
Then you simply save your file. If you want to use the system crontab you will have to edit it directly and enter the line. Additionally the system crontab has one more field for the username. Like this:
* * * * * /usr/bin/php root /Applications/MAMP/htdocs/php_test/main_script.php
On the next full minute your script will be executed by crond.

PHP Cronjob does not execute

I am running Ubunutu Linux server, PHP5, Apache2 and am having trouble getting any sort of cronjob to run through the crontab.
I edit the crontab using
crontab -e
I save the file I want to run:
*/5 * * * * php /home/user/public_html/crx/cronx.php
it saves fine. I can run the file from the console and goes through fine. I can't even find any existing logs for the file. I checked cron was running, stopped and started... no change.
The current php file is just a simple test script that inserts a single line into a database.
I checked the permissions for the file and has read and write. Am absolutely stumped. I can't seem to get ANYTHING to run through cron. Is there something I can run to test permissions?
EDIT
I have also tried the following command
/usr/bin/php /home/user/public_html/crx/cronx.php
I used whereis php and which php to locate and confirm it is all running in the right area
You have too many * values for your times.
Also, cron may not have a PATH set up correctly to use PHP.
Instead try:
*/5 * * * * /usr/bin/php /home/user/public_html/crx/cronx.php
Where /usr/bin/php is the actual path to PHP. From the console you can run which php to see the path to the PHP binary you should use.
EDIT: Here are a couple of more things to try in order to troubleshoot:
# see if cron is running just by having it create a file
*/5 * * * * touch /tmp/crontab-$(date +%s)
Another option:
Set the permissions of your PHP script to 755, and change the beginning to:
#!/usr/bin/php -q
<?php
// rest of script
Then change your cron tab to:
*/5 * * * * /home/user/public_html/crx/cronx.php
I'm still not sure if cron is the issue or the running of the PHP script.

Trying to get php to run on cron

This is driving me a little insane, and I've gone through a hundered different things without touching on the solution; so I may miss out on some details on what I've done so far.
I'm trying to get a Cron job to run on my linux server ive got running in a datacentre. All I'm trying to get to run is a simple php script in the format:
* * * * * php -q /path/to/script/file.php
The php part runs fine if I type it in manually, but nothing happens when the cron runs; it also appears to run in the logs just fine, with no errors.
If i go back and edit with crontab -e, and put in the line
* * * * * echo "test" > /tmp/test.txt
That seems to work ok, it creates the text file.
Has anyone had any problems running a php script in this format?
(Btw I'm just testing with the run every minute, it doesnt work at any time.)
Any help is appreciated.
try invoking php with it's full path, for example /usr/bin/php
the cron will not have the same environment variables as your user profile have, so it might not find the executable.
Try to put full path to php binary (/usr/bin/php or similar)
I also don't have '-q' flag in my distribution. Check it.
Might just be some path craziness: I'd run which php and then copy the full path into cron. On one of my boxes it is /usr/bin/php and so you'd have:
* * * * * /usr/bin/php -q /path/to/script/file.php
Try that and see if it helps.
Perhaps your PHP binary is not in your PATH. Try using the full path:
* * * * * /path/to/php -q /path/to/script/file.php
It's possible that you may need to provide the full path to your php binary
* * * * * /usr/bin/php -q /path/to/script/file.php
