Bug description:[feat] md5_file and sha1_file should accept an additional length
Description:
------------
Sometimes you want to have the md5() or sha1() from a file, but not the
whole file. This is particularly handy when you want to sync directories
and you don't want to md5 whole files but just the first 4096 or 8192 bytes
to speed up the checking.
This patch implements an additional parameter to md5_file() and sha1_file()
where you can add the number of bytes that needs to be read/md5()'d from
the source file.
Test script:
---------------
Returns the md5 from the first 8192 bytes from the iso-file:
md5_file('dvdimage.iso', false, 8192);
Returns the md5 from the complete file, even though length is way larger
than the file:
md5_file('dvdimage.iso', false, 81920000000);
Expected result:
----------------
The md5_file() and sha1_file() functions actually accepting the additional
parameter.
Actual result:
--------------
Currently, it does not accept a 3rd paramter. The patch adds the additional
parameter (which defaults to -1, which means to read the complete file).
Additionally added and fixed tests in md5_file.phpt and sha1_file.phpt
