Re: Executing external program ?

> $bindir="c:\mysql\bin\"; That's pretty broken -- \ has special meaning... I'm guessing that PHP might be doing the right thing, since you didn't coincidentally hit upon any of the wrong characters except \", though I'm not at all sure how that slips by... This line alone should be giving you an error message... Change all the \ to / in pathnames and save yourself some headaches. > > passthru( $bindir."mysqldump --quick shop > bkup.txt " ) or Die('Couldnt Query '.mysql_error()); > echo ("Program ran successfully"); This probably doesn't output anything -- You've dumped all the output to bkup.txt Is bkup.txt being filled with the correct data? What path are you expecting bkup.txt to be in?... You may need it to be a world-writable directory -- or at least one writable by the user that IIS runs as, which under NT is that "Iusr_machinename" user, I think...
