使用php解析智能搜索

Question

我正在使用PHP和jquery构建一个UI，允许用户输入一个字符串，然后搜索apt search

我想要做的是分离(使用php) packaga name、the architecture (就在/之后)和description of the package (就在包和体系结构的线下)，这样我就可以将这些数据压缩到JSON集合中并返回给jQuery。

我正在执行以下命令：

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

我可以在/上使用but获得包名和体系结构，但不知道如何获得下面的行

下面是针对php的搜索的示例输出

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)

xmlsysd/bionic 2.6.0-0ubuntu4 amd64
  wulfware daemon to extract data from cluster nodes

yasat/bionic 848-1ubuntu1 all
  simple stupid audit tool

  Yubikey validation server

yubikey-val/bionic 2.38-2 all
  One-Time Password (OTP) validation server for YubiKey tokens

zendframework/bionic 1.12.20+dfsg-1ubuntu1 all
  powerful PHP framework

zendframework-bin/bionic 1.12.20+dfsg-1ubuntu1 all
  binary scripts for zendframework

谢谢你的帮助！

这里有几种方法可以做到。

一种是使用array_map (您可以使用普通的foreach )，另一种是使用regex的方式。

<?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));

或者用regex

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);

两者产生的结果是相同的：
