>&#13;    You can make your configuration files work with both versions
    of PHP (depending on which one is currently compiled into the
    server), using the following syntax:

NAME="AEN104087"

>&#13;    In addition,  the PHP directive names for Apache have changed.
   </P

>&#13;    Starting with PHP 4.0, there are only four Apache directives
    that relate to PHP:
    <DIV

   </P
><P
>&#13;    There are two differences between the Admin values and the non admin values:
   </P
><P
></P
><UL
><LI
><P
>Admin values (or flags) can only appear in the server-wide apache configuration files (e.g., httpd.conf).</P
></LI
><LI
><P
>Standard values (or flags) cannot control certain PHP directives, for example - safe mode (if you could override safe mode settings in .htaccess files, it would defeat safe-mode's purpose).  In contrast, Admin values can modify the value of any PHP directive.</P
></LI
></UL
><P
>&#13;    To make the transition process easier, PHP 4 is bundled with scripts that automatically convert your Apache configuration and .htaccess files to work with both PHP 3 and PHP 4. These scripts do NOT convert the mime type lines! You have to convert these yourself.
   </P
><P
>&#13;    To convert your Apache configuration files, run the apconf-conv.sh script (available in the scripts/apache/ directory).  For example:
    <DIV
CLASS="informalexample"
><A
NAME="AEN104101"
></A
><P
></P
><TABLE

BGCOLOR="#E0E0E0"

></TD
></TR
></TABLE
><P
></P
></DIV
>
   </P
><P
>&#13;    Your original configuration file will be saved in httpd.conf.orig.
   </P
><P
>&#13;    To convert your .htaccess files, run the aphtaccess-conv.sh script (available in the scripts/apache/ directory as well):
    <DIV
CLASS="informalexample"
><A
NAME="AEN104105"
></A
><P
></P
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"

CLASS="shell"

></TD
></TR
></TABLE
><P
></P
></DIV
>
   </P
><P
>&#13;    Likewise, your old .htaccess files will be saved with an .orig prefix.
   </P
><P
>&#13;    The conversion scripts require awk to be installed.
