IIRC, that was a very deliberate change/fix. Previous Comments: ------------------------------------------------------------------------ [2019-11-29 10:57:37] php-bugs at xpaw dot me Description: ------------ See https://3v4l.org/58RgW Until 7.4.0beta1, it returned string(32) "d41d8cd98f00b204e9800998ecf8427e" and since 7.4.0beta2 it displays a notice. Notice: hash_file(): read of 8192 bytes failed with errno=21 Is a directory in /in/58RgW on line 3 On Windows there is no notice, and it only returns false. I'm only creating this issue as I don't see anything in upgrading notes, deprecated features or the changelog about it. Test script: --------------- <?php var_dump( hash_file( 'md5', '/etc/' ) ); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78885&edit=1
