Hi there,
I am running a php file via cron where zip files will be extracted with
the help of zip_entry_read. This worked great until I had a corrupted
zip file to extract. This braught the server down as the php script
never ended. The function max_execution_time does not help as it zip is
a system function so the php script did run endless until the cron job
trigered the next execution a minute later and so on!
It seams that the zip_entry_read function is buggy. I found 2 people
with the similar problem, but no solution:

When I do a unzip on the console I do get following error from zip:
unzip 25_459.zip
Archive: 25_459.zip
error [25_459.zip]: missing 2203 bytes in zipfile
(attempting to process anyway)
retry - request = 0x4294965093
error [25_459.zip]: attempt to seek before beginning of zipfile
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

file #7: bad zipfile offset (local header sig): 524802
file #8: bad zipfile offset (local header sig): 615587
How can i make zip_entry_read exit on error to solve the problem?
Thank you for any idea,
Merlin
