使用 php 解析能力搜索

Parse aptitude search using php

我正在使用 PHP 和 jquery 构建一个 UI,它将允许某人输入字符串并搜索 apt search

我想做的是分开(使用php)packaga namethe architecture 就在/ 之后,description of the package 就在description of the package 下面包和体系结构的行,因此我可以将这些数据推送到 JSON 集合中,并将其 return 推送到 jQuery.

我正在执行以下命令:

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

我可以在 / 上使用 explosion 获取包名称和体系结构,但不知道如何获取下面的行

这是针对 php 进行搜索的示例输出:

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

xjed/bionic 1:0.99.19-7 amd64
  editor for programmers (x11 version)

感谢您的协助!

更新:

我可以使用爆炸“/”获取包名和体系结构,但我不知道如何获取下面的行。以为我可以找到一个漂亮的解决方案

这里有几种方法。

一种是使用 explode with array_map(您可以使用普通的 foreach 代替),另一种是使用正则表达式。

<?php
$str = 'wwwconfig-common/bionic 0.3.0 all
  Debian web auto configuration

...';
  
  
$packages = array_map(function($item) {
    
    $item = array_map('trim', explode("\n", trim($item)));
    $line = explode(" ", $item[0]);
    $line[0] = explode("/", $item[0]);
    
    return [
        'package' => $line[0][0],
        'distro' => $line[0][1],
        'version' => $line[1],  
        'arch' => $line[2], 
        'desc' => $item[1]
    ];
}, explode("\n\r", $str));

或使用正则表达式,

preg_match_all('#(?<package>.*?)/(?<distro>.*?) (?<version>.*?) (?<arch>.*?)\n  (?<desc>.*?)\n\r#', $str, $packages);
$result = [];
foreach ($packages['package'] as $key => $value) {
    $result[] =  [
        'package' => $packages['package'][$key],
        'distro' =>  $packages['distro'][$key],
        'version' =>  $packages['version'][$key],
        'arch' =>  $packages['arch'][$key],
        'desc' =>  $packages['desc'][$key]
    ];
}

print_r($result);

两者产生相同的结果:
