In particular, seeking is completely broken. Basically the stream works only when used forward-only, consume-once (eg: file_get_contents('php://input')). I didn't found the bug reported here (I searched under streams related bugs using the 'seek' keyword). I sketched a possible fix with tests here: https://github.com/php/php-src/compare/PHP-7.1...davide-romanini:fix-php-stream-input-seek Test script: --------------- --POST-- Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum ante ex, placerat nec sollicitudin vitae, ultricies molestie nisi. Maecenas lacus magna, augue. --FILE-- <?php $i = fopen('php://input', 'r'); fseek($i, 5); var_dump(fread($i, 10)); rewind($i); var_dump(fread($i, 5)); fseek($i, -6, SEEK_END); var_dump(fread($i, 6)); ?> --EXPECT-- string(10) " ipsum dol" string(5) "Lorem" string(6) "augue." ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75894&edit=1
