在 lambda 中运行 os.system 模块时遇到“sh: php: command not found”错误

Question

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.

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.

Answer 1

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

So you have three options:

1. Migrate your PHP code to Python.
2. 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 .
3. 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 .

Answer 2

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()
