Test a zip file for validity

Hello all,

How do I go about checking if a file is a zip file?

Wrapping the zipinfo utility in php did not help since it does not return an
exit code whether it succeeded or not.

Thanks,

I'm assuming the zipinfo your talking about is part of the unzip
package. You should use unzip to test the files

unzip -t file.zip

will check the checksum for each file.

'man unzip' for further details.
