encountered “sh: php: command not found” error while running os.system module in lambda

问题

I'm trying to run a php script in aws lambda using python runtime. I tried using python os.system module to call the php page to execute the script. The code is given below

import os
def lambda_handler(event, context):
    os.system("php /home/admin/web/####/###.php")

On running the above code, it displays error: "sh: php: command not found". I do not have much knowledge either in python scripting or shell scripting. So any help would be much appreciated.

By the way merry christmas to all of you.

Update: New code

def lambda_handler(event, context):
    stream = os.popen("/usr/bin/php /home/admin/web/path/")
    output = stream.read()
    print(output)

Used the new code but its displaying this error now: /bin/sh: /usr/bin/php74: No such file or directory.

I don't understand, because php is installed into the system , but yet it is telling no such file exists.

You can not run PHP scripts in the default Python Lambda runtime. There is no PHP installed.

So you have three options:

Migrate your PHP code to Python.
Create a Docker image with Python and PHP and use it as Lambda runtime. This feature was added recently, you can read about it this blog post.
Create a custom Lambda runtime, as described in the documentation.

Your original question contained the PHP script, that you want to run. It only contained a very trivial MySQL query. It should be very easy to migrate that one line of PHP code to Python.

The PHP code:

<?php
$con1 = mysqli_connect("endpoint","###","###","database");
if(mysqli_query($con1,"insert into ex_inbox(time) values ('Done')") or die("the eror ".mysqli_error($con1)));
?>

Therefore, option #1 is the one I'd recommend. You can read how to do insert into a MySQL database using Python in this guide.

Please specify the full path!!!

for example:

The actual PHP path should be based on your own

/####/####/php/72/bin/php /home/admin/web/####/###.php

My Python code

import os


def main():

    stream = os.popen("C:/Users/Administrator/Desktop/php/xxx/xxx/php/php7.2.9nts/php  C:/xxx/xxx/WWW/test/test1.php")
    output = stream.read()
    print(output) # Successful and effective execution

if __name__ == '__main__':
    main()
