PHP 8 ChangeLog

8.3 | 8.2 | 8.1 | 8.0

Version 8.3.8

  • CGI:
    • Fixed buffer limit on Windows, replacing read call usage by _read.

These changes are part of OpenSSL 3.2 and have also been backported to stable versions of various Linux distributions, as well as to the PHP builds provided for Windows since the previous release. All distributors and builders should ensure that this version is used to prevent PHP from being vulnerable.

  • MBString:
    • mb_detect_encoding is better able to identify the correct encoding for Turkish text.
    • mb_detect_encoding's "non-strict" mode now behaves as described in the documentation. Previously, it would return false if the same byte (for example, the first byte) of the input string was invalid in all candidate encodings. More generally, it would eliminate candidate encodings from consideration when an invalid byte was seen, and if the same input byte eliminated all remaining encodings still under consideration, it would return false. On the other hand, if all candidate encodings but one were eliminated from consideration, it would return the last remaining one without regard for how many encoding errors might be encountered later in the string. This is different from the behavior described in the documentation, which says: "If strict is set to false, the closest matching encoding will be returned." (Alex Dowad)
    • mb_strtolower, mb_strtotitle, and mb_convert_case implement conditional casing rules for the Greek letter sigma. For mb_convert_case, conditional casing only applies to MB_CASE_LOWER and MB_CASE_TITLE modes, not to MB_CASE_LOWER_SIMPLE and MB_CASE_TITLE_SIMPLE.
    • mb_detect_encoding is better able to identify UTF-8 and UTF-16 strings with a byte-order mark.
    • mb_decode_mimeheader interprets underscores in QPrint-encoded MIME encoded words as required by RFC 2047; they are converted to spaces. Underscores must be encoded as "=5F" in such MIME encoded words.
    • mb_encode_mimeheader no longer drops NUL (zero) bytes when QPrint-encoding the input string. This previously caused strings in certain text encodings, especially UTF-16 and UTF-32, to be corrupted by mb_encode_mimeheader.
    • Implement mb_str_pad() RFC.
    • Fixed bug GH-11514 (PHP 8.3 build fails with --enable-mbstring enabled).
    • Fix use-after-free of mb_list_encodings() return value.
    • Fixed bug GH-11992 (utf_encodings.phpt fails on Windows 32-bit).
  • mysqli:
    • mysqli_fetch_object raises a ValueError instead of an Exception.
  • Opcache:
    • Added start, restart and force restart time to opcache's phpinfo section.
    • Fix GH-9139: Allow FFI in opcache.preload when opcache.preload_user=root.
    • Made opcache.preload_user always optional in the cli and phpdbg SAPIs.
    • Allows W/X bits on page creation on FreeBSD despite system settings.
    • Added memfd api usage, on Linux, for zend_shared_alloc_create_lock() to create an abstract anonymous file for the opcache's lock.
