为 php 5.3.3-7+squeeze17 安装 imap 扩展

Install imap extension for php 5.3.3-7+squeeze17

服务器安装了 debian wheezy os。 Php 版本为 php5.3:

 user@example:~# php -v
 PHP 5.3.3-7+squeeze17 with Suhosin-Patch (cli) (built: Aug 23 2013 15:06:16) 

我尝试通过 apt-get 安装 imap 扩展,结果是:

user@example:~# apt-get install php5-imap=5.3.3-7+squeeze17
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Version '5.3.3-7+squeeze17' for 'php5-imap' was not found

当我尝试另一个版本时,我得到:

user@example:~# apt-get install php5-imap=5.3.3-7+squeeze19
Reading package lists... Done
Building dependency tree

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php5-imap : Depends: php5-common (= 5.3.3-7+squeeze19) but 5.3.3-7+squeeze17 is to be installed
E: Unable to correct problems, you have held broken packages.

有人知道在这种情况下安装 php5-imap 的最安全方法吗? P.S。从 wheezy repo 更新到 5.4 不是解决方案:(

我通过调用使用 imaplib (http://pymotw.com/2/imaplib/) 的外部 python 脚本解决了这个问题。 从 php 调用 python 的示例:

 <? exec("python <ABSOLUTE_PATH_TO_SCRIPT>.py " . escapeshellarg($arg1));
