LAMP堆栈的PHP无法正常工作（Ubuntu 13.10 / Apache 2.4.6）

Question

Having problems with PHP on my LAMP stack: PHP scripts aren't being parsed at all. I setup Ubuntu 13.10 on clear machine... And I see now there only clear HTML from page but PHP tags are just like text

Actually, what I have:

$ /usr/sbin/apache2ctl status | grep Version

Server Version: Apache/2.4.6 (Ubuntu) PHP/5.5.3-1ubuntu2.1

$ tail -n 1 /var/log/apache2/error.log

$ apache2ctl -S

UPD.1: it's mine apache2.conf : http://ge.tt/6Yd8Jj91/v/0

UPD.2: Today I умут tried to remove everything and just re-install LAMP. The result is exactly the same: PHP does not works.

sudo apt-get install lamp-server^

But also interesting that phpmyadmin works fine. I just install it as:

sudo apt-get install php5 php5-cgi phpmyadmin 

It turns out that there (in phpmyadmin) are some settings that give it to use PHP...

Answer 1

Just had the same problem. You have to use <?PHP instead of <? or change the following config:

/etc/php5/apache2/php.ini

; This directive determines whether or not PHP will recognize code between
; <? and ?> tags as PHP source which should be processed as such. It's been
; recommended for several years that you not use the short tag "short cut" and
; instead to use the full <?php and ?> tag combination. With the wide spread use
; of XML and use of these tags by other languages, the server can become easily
; confused and end up parsing the wrong code in the wrong context. But because
; this short cut has been a feature for such a long time, it's currently still
; supported for backwards compatibility, but we recommend you don't use them.
; Default Value: On
; Development Value: Off
; Production Value: Off
; http://php.net/short-open-tag
short_open_tag = On

Answer 2

Check if you have these lines in your httpd.conf:

AddType  application/x-httpd-php         .php
AddType  application/x-httpd-php-source  .phps

Also make sure your php module is loaded:

LoadModule php5_module        modules/mod_php55.so

After that, restart apache and clear your browser's cache before retrying.

Answer 3

For some reason default virtual host is not executing php by default: https://askubuntu.com/questions/407744/apache-doesnt-execute-php-files-but-makes-me-download-them

Enable php engine explicitly:

<IfModule mod_php5.c>
    php_admin_flag engine on
</IfModule>
