Is PHP installation correct?

In Linux, after installing apache web server from source apache_1.3.27.tar.gz, I have installed PHP from source as the followings: #cd /usr/src #gzip -d php-4.2.3.tar.gz #tar xvf php-4.2.3.tar #cd php-4.2.3 #./configure --with-mysql=/usr \ --with-xml --with-apache=../apache_1.3.27 \ --with-curl=../curl \ --enable-shared-pdflib #make #make install #cp php.ini-recommented /usr/local/lib/php.ini ...... then I added the following lines into /usr/local/apache/conf/httpd.conf: #And for php 4.x use: # AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phpd then I created a new file of test.php in /usr/local/apache/htdocs/ with one line: <?php phpinfo(); ?> to test, that is, in Mozilla browser I typed: http://localhost/test.php there was no the standard page with phpinfo() displayed; instead, only "<?php phpinfo(); ?>" displayed., indicating that PHP has not worked right? So what is the cause with this situation? Sincerely Lili Zhang
