When calling finfo_buffer() from class method context, warning is emmited. It looks like the function is thinking that is finfo::buffer(). When I uncomment the first call in test below, I get SIGSEGV. Test script: --------------- // var_dump(finfo_buffer(finfo_open(FILEINFO_MIME_TYPE), '<!DOCTYPE html>')); class Test { public function detect() { return finfo_buffer(finfo_open(FILEINFO_MIME_TYPE), '<!DOCTYPE html>'); } } var_dump(finfo_buffer(finfo_open(FILEINFO_MIME_TYPE), '<!DOCTYPE html>')); var_dump((new Test)->detect()); Expected result: ---------------- string(9) "text/html" string(9) "text/html" Actual result: -------------- string(9) "text/html" Warning: finfo_buffer() expects parameter 2 to be long, string given in /tmp/php7/finfo.php on line 7 bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68250&edit=1
