使用 php 解析 aptitude 搜索

Question

我正在使用 PHP 和 jquery 构建一个 UI，它允许某人输入字符串并进行搜索apt search

我想要做的是分离（使用 php）packaga name，就在包和架构的行the architecture之后/和正下方，这样我就可以将此数据推送到 JSON 集合中并将其返回给 jQuery。description of the package

我正在执行以下命令：

$data=shell_exec("sudo apt search $searchString")

我可以使用爆炸获取包名称和架构，/但不知道如何获取下面的行

以下是此搜索的示例输出php：

wwwconfig-common/bionic 0.3.0 all

  Debian web auto configuration

xine-ui/bionic 0.99.9-1.3 amd64

  the xine video player, user interface

感谢您的帮助！

我可以使用爆炸“/”获取包名称和体系结构，但我不知道如何获取下面的行。我想我能找到一个漂亮的解决方案

这里有几种方法可以做到这一点。一种是使用 array_map 进行爆炸（您可以使用普通的 foreach 代替），另一种方法是使用正则表达式。<?php$str = 'wwwconfig-common/bionic 0.3.0 all&nbsp; Debian web auto configuration...';&nbsp;&nbsp;&nbsp;&nbsp;$packages = array_map(function($item) {&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; $item = array_map('trim', explode("\n", trim($item)));&nbsp; &nbsp; $line = explode(" ", $item[0]);&nbsp; &nbsp; $line[0] = explode("/", $item[0]);&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; return [&nbsp; &nbsp; &nbsp; &nbsp; 'package' => $line[0][0],&nbsp; &nbsp; &nbsp; &nbsp; 'distro' => $line[0][1],&nbsp; &nbsp; &nbsp; &nbsp; 'version' => $line[1],&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; 'arch' => $line[2],&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; 'desc' => $item[1]&nbsp; &nbsp; ];}, explode("\n\r", $str));或者使用正则表达式，preg_match_all('#(?<package>.*?)/(?<distro>.*?) (?<version>.*?) (?<arch>.*?)\n&nbsp; (?<desc>.*?)\n\r#', $str, $packages);$result = [];foreach ($packages['package'] as $key => $value) {&nbsp; &nbsp; $result[] =&nbsp; [&nbsp; &nbsp; &nbsp; &nbsp; 'package' => $packages['package'][$key],&nbsp; &nbsp; &nbsp; &nbsp; 'distro' =>&nbsp; $packages['distro'][$key],&nbsp; &nbsp; &nbsp; &nbsp; 'version' =>&nbsp; $packages['version'][$key],&nbsp; &nbsp; &nbsp; &nbsp; 'arch' =>&nbsp; $packages['arch'][$key],&nbsp; &nbsp; &nbsp; &nbsp; 'desc' =>&nbsp; $packages['desc'][$key]&nbsp; &nbsp; ];}print_r($result);两者产生相同的结果：Array(&nbsp; &nbsp; [0] => Array&nbsp; &nbsp; &nbsp; &nbsp; (&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
