System() Return Values

[RayTaylorII]

I am using the PHP system() function to run an unzip utility in linux (on an IBM i). system() is returning a return value of 50 and does not perform the unzip. Is there a list explaining what the various system() return codes?

Thanks

From the php manual entry for system: Returns the last line of the command output on success, and FALSE on failure.

I did see that in the PHP manual, but the command does not complete, so I would expect a false, but the return code is 50. 50 isn't part of the command output?

 

This is the actual line of code being executed:

 

system("unzip -qq  -P password /FTPRTLORD/ORDERS/ROrders_01012012_000501.ZIP -d /FTPRTLORD/ORDERS/",$retValue);

 

$retValue comes back 50.

AFAIK, system() returns FALSE if system() fails to execute, not the command within it. The value is what is being returned from the command. Have you run the command from the CLI?

I run the command in the linux command line interace on the IBM i and it runs fine.

Does the PHP/web user have permissions to run the command?

Yes

Then I'm out of ideas . . .

Actually, you are dead on!!!! I assumed (and you know what that does) that the user name I used to connect to the database was the same user who was used to run system commands...not so. Once I found the correct user being used, I updated permissions for that user and it works....

Thanks so much!!!!
