    Runtime Configuration

    The behaviour of these functions is affected by
    settings in php.ini.

    Exif supports automatically conversion for Unicode
    and JIS character encodings of user comments when module mbstring is available. This is
    done by first decoding the comment using the specified
    characterset. The result is then encoded with another characterset
    which should match your HTTP output.

    Here’s a short explanation of the configuration
    directives.

    exif.encode_unicode string

    exif.encode_unicode defines the
    characterset UNICODE user comments are handled. This defaults to
    ISO-8859-15 which should work for most non Asian countries. The
    setting can be empty or must be an encoding supported by mbstring.
    If it is empty the current internal encoding of mbstring is
    used.

    exif.decode_unicode_motorola string

    exif.decode_unicode_motorola defines the
    image internal characterset for Unicode encoded user comments if
    image is in motorola byte order (big-endian). This setting cannot
    be empty but you can specify a list of encodings supported by
    mbstring. The default is UCS-2BE.

    exif.decode_unicode_intel string

    exif.decode_unicode_intel defines the
    image internal characterset for Unicode encoded user comments if
    image is in intel byte order (little-endian). This setting cannot
    be empty but you can specify a list of encodings supported by
    mbstring. The default is UCS-2LE.

    exif.encode_jis string

    exif.encode_jis defines the characterset
    JIS user comments are handled. This defaults to an empty value
    which forces the functions to use the current internal encoding of
    mbstring.

    exif.decode_jis_motorola string

    exif.decode_jis_motorola defines the image
    internal characterset for JIS encoded user comments if image is in
    motorola byte order (big-endian). This setting cannot be empty but
    you can specify a list of encodings supported by mbstring. The
    default is JIS.

    exif.decode_jis_intel string

    exif.decode_jis_intel defines the image
    internal characterset for JIS encoded user comments if image is in
    intel byte order (little-endian). This setting cannot be empty but
    you can specify a list of encodings supported by mbstring. The
    default is JIS.
