I've been trying to run the php script:
shell_exec("bash /etc/example.sh")
from the browser but it does not work. This bash file creates a new one on the /etc directory.
I've also tried the functions exec() && system() but they don't work either. The weird thing happens when I run other Linux commands on these php function like:
shell_exec(rm -r /etc/fake);
they work fine, I have also tested my bash file on the linux command line and it works great.
I am sure this is not a permission issue, since I previously set the 777 permission on the file i am trying to execute.
shell_exec("bash /etc/example.sh")
I am using php7.0.33 and Debian 9, so I suppose this may be an issue with this PHP version 7.0.
Thank you for the help.
Hello i have a PHP script, and its added to cron, it is possible to execute from this script shell command (with exec() or something) without enabling it on php.ini? I don't want to enable exec on my site
It's called PHP CLI, check here
Usually when you install php, there's option to install php_cli too.
So long you can run php on shell prompt, then it can work.
Open bash (or other shell), try this:
php -v
If the version printed, then it's working.
Then you can
php -f phpfile
or put
#!/usr/bin/php
At the beginning of your php file as a line, and chmod +x file.php, and then
./file.php
#or
/path/to/file.php
to run it.
(Note /usr/bin/php is the usual place of php executable, it might change, eg in unix is ually /bin/php. Use whereis php to check its place.)
I have a python script (wap.py) from which I am calling wapiti asynchronously using Popen. Command for it in wap.py:
p = Popen("python wapiti domainName", shell = True)
When I am running wap.py, it is executing completely fine.
But when I am running it using php exec, it doesn't work.
Command from php file : exec("python wap.py")
Look at the php.ini to see if there's anything set for disable_functions. If you're using PHP CLI for the script, you can execute the following command in the shell:
php -i | grep disable_functions
Also make sure wap.py has execute permissions.
I can run facebook.php script from ssh below:
cd /var/www/
php facebook.php
But I want to run to script 1 line command because i want to use it on cron. Like this:
php /var/www/facebook.php
I tried other commands on ssh but dont worked. Only first command is worked for me
if /usr/bin/php /var/www/facebook.php is not working, it might a case of your php path is different then /usr/bin/php.
I have a php script that I want to be run using a bash script, so I can use Cron to run the php script every minute or so.
As far as I'm aware I need to create the bash script to handle the php script which will then allow me to use the Cron tool/timer.
So far I was told I need to put:
#!/pathtoscript/testphp.php
at the start of my php script. Im not sure what to do from here...
Any advice? Thanks.
If you have PHP installed as a command line tool (try issuing php to the terminal and see if it works), your shebang (#!) line needs to look like this:
#!/usr/bin/php
Put that at the top of your script, make it executable (chmod +x myscript.php), and make a Cron job to execute that script (same way you'd execute a bash script).
You can also use php myscript.php.
Sometimes PHP is placed in non standard location so it's probably better first locate it and then try to execute.
#!/usr/bin/env bash
PHP=`which php`
$PHP /path/to/php/file.php
A previous poster said..
If you have PHP installed as a command line tool… your shebang (#!) line needs to look like this: #!/usr/bin/php
While this could be true… just because you can type in php does NOT necessarily mean that's where php is going to be... /usr/bin/php is A common location… but as with any shebang… it needs to be tailored to YOUR env.
a quick way to find out WHERE YOUR particular executable is located on your $PATH, try..
➜which -a php ENTER, which for me looks like..
php is /usr/local/php5/bin/php
php is /usr/bin/php
php is /usr/local/bin/php
php is /Library/WebServer/CGI-Executables/php
The first one is the default i'd get if I just typed in php at a command prompt… but I can use any of them in a shebang, or directly… You can also combine the executable name with env, as is often seen, but I don't really know much about / trust that. XOXO.
You just need to set :
/usr/bin/php path_to_your_php_file
in your crontab.
I'm pretty sure something like this is what you are looking for:
#!/bin/sh
php /pathToScript/script.php
Save that with your desired script name (such as runPHP.sh) and give it execution rights, then you can use it however you want.
Edit: You might as well not use a bash script at all and just add the "php ..." command to the crontab, if I'm not mistaken.
Good luck!
The bash script should be something like this:
#!/bin/bash
/usr/bin/php /path/to/php/file.php
You need the php executable (usually found in /usr/bin) and the path of the php script to be ran. Now you only have to put this bash script on crontab and you're done!
a quick way to find out WHERE YOUR particular executable is located on your $PATH, try.
Even quicker way to find out where php is ...
whereis php
I'm running debian and above command showing me
php: /usr/bin/php /usr/share/php /usr/share/man/man1/php.1.gz
Hope that helps.
If you don't do anything in your bash script than run the php one, you could simply run the php script from cron with a command like /usr/bin/php /path/to/your/file.php.
I found php-cgi on my server. And its on environment path so I was able to run from anywhere. I executed succesfuly file.php in my bash script.
#!/bin/bash
php-cgi ../path/file.php
And the script returned this after php script was executed:
X-Powered-By: PHP/7.1.1
Content-type: text/html; charset=UTF-8
done!
By the way, check first if it works by checking the version issuing the command php-cgi -v
Create file.php with first line in files: file.php(#!/bin/php) file.sh(#!/bin/bash).
Check installed php.Run command in terminal:
which php
If set there will be an answer:
/usr/bin/php
Run file.php with command:
php file.php
if the file has started then you can write this command to file.sh:
#!/bin/bash
run_php=`php file.php`
echo $run_php
Be careful ' and ` different!!!
