PHP exec not working for command that works in bash and python -

-



so i'm not sure what's going here , cannot figure out why.

the command:

echo shell_exec('wine /var/www/exes/validate_file.exe /var/www/exes/test_files/test1.txt');

outputs nothing (i expect printing "ok"). running same command through python os.system shows expected output ("ok") , on bash command line.

if run different exe through wine, works expected, i'm not sure what's going on, permissions fine (i've tried 777 on both exe , txt, , wine worked different exe). i've tried putting command python file , wrapping php didn't produce output.

the string exec ( string $command [, array &$output [, int &$return_var ]] ) has 3 arguments , result last line result of command. possible empty result if last line empty. output of executed command, sure set , use output parameter. status of command use return_var argument. if return_var argument present along output argument, return status of executed command written variable. if need execute command , have data command passed directly without interference, use passthru() function.

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
