note 78549 deleted from function.md5 by danbrown

Note Submitter: Santa Cruz skelly ---- Re: public at kreinacke dot com It has long been a point of frustration to me that md5() functions don't produce the same results as the *nix md5sum program. Reading your comments about the incongruity today pushed me over the edge to finally understand why. The answer, I believe I have found, is that md5sum includes an extra newline as the termination of the file content. ugh. In response I have produced the following function that, at least on my server, produces a result matching the output of md5sum on the command line: function md5sum($str) { return(md5($str . "\n")); } Yes, that easy. My results from typing the string "apples and oranges" into a PHP script using that function and the same string entered into a file on disk using md5sum on the command line to pull it return: 6c1111418017a050006eee9f2bdda2bf Your echo -n "apples and oranges | md5sum method (which suppresses that newline I refer to!) and PHP's normal md5() function also return the same result as one another as you described, but those are string based operations. My solution is a function that reproduces the result of md5sum's assessment of on-disk data based on the contents of the file being in a string, something that's critical to my application.
