[Resolved] exec() problems...

[stew]

hey there guys...

• this may be in the wrong forum.... sorry!

im calling the exec function in the following manner:

exec("blastall -p blastp -d blast_db.txt -i blast_query.txt > blast_results.txt");

the above statement executes fine from the command line, but when called from exec(), the output of the program isn't sent to the blast_results.txt file...

can anyone think of any reason why this is the case?

thanks,

Stewart

You getting any errors? What about in the error_logs as well? Maybe using the [man]system[/man] function until its sorted out especially looking at the return variable.

[edit]
Also you should probably give the absolute path and check if safe_mode is enabled if so read up in those functions Ive forgotten exactly what you can do if safe_mode is enabled

if i change it to system() the return value is 127. Other than that there doesn't appear to be any errors relating to that in the php script... also there are no error log files associated with that particular program. is there a general error log that it could be written to?

also, i added the other two parameters to the exec() function and the array as the second parameter (the output of the script), was empty and the returned value was 127.

127 normally means there was an error. Error should be in the /path/to/apache/logs/error_log

Like I said in my original post in the edit

Is Safe Mode on?
Did you have the absolute path to program to execute?
You should also make error go into the logs to check in the php.ini check if log_errors is on if not change it to On and restart the server run the script and check the error logs.

unfortunately i dont have control of the server, its a university server and i have no access to configurations!

I added the path to the program and the output files and it worked perfectly!

thanks for your help...!
