Thanks stomp
Hello Mr. Don, the third party is sending us a zip file , presently they are not sending checksum but it is a good idea to ask them also to send checksum. But i don't understand by your statement
PHP Code:
Download the checksum in a separate file AFTER the download of the main file
. I guess i need to compare checksum of the file at our end with the checksum of what the other party would send ? . In that case also i need to watch continuously if the checksum have matched or not by using the same while loop. I also don't understand why not to monitoring the file.

fitscheck
fitscheck(1) PyFITS 3.0.7 fitscheck(1)
NAME
fitscheck - script to detect and fix FITS standards violations
SYNOPSIS
fitscheck [OPTION]... [FILE]...
DESCRIPTION
fitscheck is a command line script based on pyfits for verifying and updating the CHECKSUM and DATASUM keywords of FITS files. itscheck
can also detect and often fix other FITS standards violations. fitscheck facilitates re-writing the non-standard checksums originally gen-
erated by pyfits with standard checksums which will interoperate with cfitsio.
fitscheck will refuse to write new checksums if the checksum keywords are missing or their values are bad. Use --force to write new check-
sums regardless of whether or not they currently exist or pass. Use --ignore-missing to tolerate missing checksum keywords without com-
ment.
OPTIONS
-h, --help
Display terse usage information (help).
-k [standard | nonstandard | either | none], --checksum=[standard | nonstandard | either | none]
Choose FITS checksum mode or none. Defaults to standard.
-w, --write
Write out file checksums and/or FITS compliance fixes.
-f, --force
Do file update even if original checksum was bad.
-c, --compliance
Do FITS compliance checking, fix if possible.
-i, --ignore-missing
Ignore missing checksums.
-v, --verbose
Generate extra output.
EXAMPLES
% fitscheck --checksum either --write *.fits
Verify and update checksums, tolerating non-standard checksums, updating to standard checksum.
% fitscheck --write --force *.fits
Write new checksums, even if existing checksums are bad or missing.
% fitscheck --compliance *.fits
Verify standard checksums and FITS compliance without changing the files.
% fitscheck --checksum nonstandard *.fits
Verify original nonstandard checksums only.
% fitscheck --checksum none --compliance --write *.fits
Only check and fix compliance problems, ignoring checksums.
% fitscheck *.fits
Verify standard interoperable checksums.
% fitscheck --checksum none --write *.fits
Delete checksum keywords.
