HTTPd shows PHP code instead of executing it

Question

My setup:

# grep php /etc/httpd/conf/httpd.conf 
LoadModule php5_module  modules/libphp5.so
AddType x-httpd-php .php
AddHandler php5-script .php

# grep PHP /etc/httpd/conf/httpd.conf 
PHPIniDir /etc/

# grep open_tag /etc/php.ini 
; short_open_tag
short_open_tag = On

# /etc/init.d/httpd start
Starting httpd: [Tue Dec 04 03:26:29 2012] [warn] module php5_module is already loaded, skipping

access_log is empty. When I open index.php, it shows its content.

[root@holdsworth steve]# ls -lah /var/www/html/php/index.php 
-rwxrwxrwx. 1 root root 1.7K Oct 31 18:38 /var/www/html/php/index.php

Answer 1

Appears you have both suEXEC and SELinux enabled, so you will need to hack around to permit execution of the php script, to start off check CGI scripts are permitted:

getsebool -a | egrep 'cgi|builtin_scriptin'

If not:

setsebool -P httpd_enable_cgi 1
setsebool -P httpd_builtin_scripting 1

Also check the php scripts have the necessary extended flag, are owned and executable by the apache process, to keep both SElinux and suEXEC happy:

ls -lZ *.php

chcon -t httpd_sys_script_exec_t *.php
chmod +x *.php
chown  xxxx:yyyyyy  *.php

ls -l *.php

Alternatively, if not a public server, disable both.

First, I think you should find where you're loading mod_php a second time:

[warn] module php5_module is already loaded, skipping

I am very superstitious about Apache config files with warning messages - they mean more than they say sometimes.

Second, try a different way of getting mod_php to parse files:

<IfModule php5_module>
    <FilesMatch "\.php$">          
        SetHandler application/x-httpd-php
    </FilesMatch>  
</IfModule>

Lastly, consider where you put the directive(s) to mod_php: if you've got VirtualHost directives, you may have to enable mod_php inside that.

Answer 3

I used your configuration file and added below contents to the end of httpd.conf file. addType, AddHandler, PHPIniDir.

And it works for me on CentOS 5, without showing the contents of index.php.

Answer 4

The solution was to clear browser cache, i.e. Press CTRL-F5

php was working, but browser was giving me old version of php content.
