Question

Just a quick question, is it possible to verify the files downloaded from FTP? I am currently using ftp_get() to get my files. The only way I can think of is using ftp_size() to compare the locally saved files.

Answer 1

If you’re verifying it against another file, then use sha1 hashes to compare.

If you just want to know if the download itself completed, rely on the return of the ftp_get method

if(!ftp_get($myfile)) return 'damn';
