I'm not sure, though, whether this has been a bugfix, or a change, so I'm re-opening. Previous Comments: ------------------------------------------------------------------------ [2018-10-14 19:51:01] klewi1983 at wp dot pl Thanks for the explanation, however, it would be useful to mention the difference in the operation of the function in the document describing migration from php 5.6 to 7.0, or 7.2 to 7.3 ;-) ------------------------------------------------------------------------ [2018-10-14 11:03:00] cmb@php.net Thanks! The “new” behavior is correct according to the documentation; since $strict is FALSE, invalid Base64 characters are silently discarded. The following script confirms this: <?php $data = file_get_contents("test.bin"); $stripped = preg_replace('/[^A-Za-z0-9+\/]/', '', $data); var_dump(base64_decode($data) === base64_decode($stripped, true)); ------------------------------------------------------------------------ [2018-10-13 09:40:15] klewi1983 at wp dot pl My example file link: https://drive.google.com/open?id=1gJXkA3iJO-a4Sw1Cy9GdE1SITGxWe2Va ------------------------------------------------------------------------ [2018-10-12 14:56:36] cmb@php.net > My test file (test.bin) size is 123 KB. > How can I attach it to the bug?
