I have installed apache 1.3.27 on RedHat 8.0
and installed php 4.3.2 successfully
i then configured, compiled and installed PHP5.

so in httpd.conf it has

LoadModule php4_module libexec/libphp4.so
LoadModule php5_module libexec/libphp5.so

then later on i have added

AddType application/x-httpd-php .php # for php4 files
AddType application/x-httpd-php5 .php5 # for php5 of course

then in htdocs i have

test.php & test.php5

both containg

<?php
phpinfo();
?>

test.php works but test.php5 comes with "page can't be displayed

does anybody have a procedure i can follow for php4 & 5 to work together????

try something like
<IfModule mod_php5.c>
AddType applicatoion/x-httpd-php .php .php5
</IfModule>

if it succeeds in loading mod_php5.c (or php5) then you can run php5

hey thx man , just what i needed
