LAMP堆棧的PHP無法正常工作（Ubuntu 13.10 / Apache 2.4.6）

Question

在我的LAMP堆棧上遇到PHP問題：根本沒有解析PHP腳本。 我在清除機器上設置了Ubuntu 13.10 ......我現在看到只有頁面上的清晰HTML，但PHP標簽就像文本一樣

實際上，我有：

$ / usr / sbin / apache2ctl status | grep版本

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

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

UPD.1：這是我的apache2.conf： http ： //ge.tt/6Yd8Jj91/v/0

---

UPD.2：今天我умут試圖刪除所有內容並重新安裝LAMP。 結果完全相同： PHP不起作用。

sudo apt-get install lamp-server^

但有趣的是phpmyadmin工作正常。 我只是安裝它：

sudo apt-get install php5 php5-cgi phpmyadmin 

事實證明，（在phpmyadmin中）有一些設置可以讓它使用PHP ...

剛遇到同樣的問題。 你必須使用<?PHP而不是<? 或更改以下配置：

/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

檢查httpd.conf中是否有這些行：

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

還要確保你的php模塊已加載：

LoadModule php5_module        modules/mod_php55.so

之后，重新啟動apache並清除瀏覽器的緩存，然后重試。

出於某種原因，默認情況下默認虛擬主機不執行php： https ： //askubuntu.com/questions/407744/apache-doesnt-execute-php-files-but-makes-me-download-them

明確啟用php引擎：

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