"HK" can indicate application/zlib files. Previous Comments: ------------------------------------------------------------------------ [2020-03-18 14:40:07] scott dot newman at faa dot gov Description: ------------ PHP Version is 7.1.23 but the drop down wouldn't let me select it. Version 7.1.23 is the version that's in the repository for RedHat 7 so I think it's still relevant. To reproduce: 1) Create a text file that has content starting with "HK". 2) Use the PHP function "mime_content_type" to display the mime type. 3) The function incorrectly reports "application/zlib". Test script: --------------- <?php var_dump(mime_content_type("file.txt")); ?> Expected result: ---------------- application/zlib is reported instead of text/plain. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79394&edit=1
