I am running php 5.3.3 on rhel 6.2 with Apache 2.2.15 and am failing to get PHP code interpreted by Apache.
There are no errors (in the system log, httpd/error_log, or php_errors.log) - I have enabled error reporting in php.ini:
error_reporting = E_ALL & ~E_DEPRECATED
display_errors = On
log_errors = On
error_log = /var/log/php_errors.log
Yet, when i view my index.php, which contains the following code, from my browser, nothing appears but a white-screen:
<?php echo 'Hello php World'; ?>
When executed by php on the command line, I get the expected text output to the terminal ("Hello php World"). When, I add some HTML to index.php:
<html>
<p>Hello from within html</p>
<?php echo 'Hello php World'; ?>
</html>
and view it with my browser, it returns just "Hello from within html." However, when executed from the command line, I get:
<html>
<p>Hello from within html</p>
Hello php World</html>
So, the PHP is parsed and interpreted via the CLI, but not by Apache.
I have confirmed that index.php and its parent file structure are owned by apache:apache and that the selinux context of the apache modules :
chcon -t httpd_sys_script_exec_t /usr/lib/httpd/modules/*
chcon -t httpd_sys_script_exec_t /usr/lib/php/modules/*
and of the .php files to be parsed:
chcon -R -h -t httpd_sys_content_t /export1
are correct. I don't think selinux is the problem because I don't get any permission errors, and I've temporarily disabled selinux echo 0 >/selinux/enforce with no success.
The php module is being loaded with its configuration and the .php extension is being understood as configured in httpd.conf:
LoadModule php5_module /usr/lib/httpd/modules/libphp5.so
AddType application/x-httpd-php .php .phtml
PHPIniDir /etc/
And, apache knows to look for index.php from:
DirectoryIndex index.html index.html.var index.php
as set in httpd.conf.
I have exhausted my ideas of where my problem is - even tried reinstalling PHP - and sure would appreciate any ideas. In case it's of use, here are the contents of /var/log/httpd/error_log when I start up apache:
