使用PHP解析智能搜索

问题描述

我正在使用PHP和jquery构建UI，这将允许某人键入字符串，并且它将搜索apt search

我想做的是将packaga name，the architecture和/分开（使用php），紧跟在包和体系结构行的下面这样我就可以将这些数据推送到JSON集合中并将其返回给jQuery。

我正在执行以下命令：

description of the package

我可以在$data=shell_exec("sudo apt search $searchString") 上使用爆炸来获取包名称和体系结构，但不知道如何获得下面的行

以下是此搜索针对/的示例输出：

php

感谢您的帮助！

更新：

我可以使用爆炸的“ /”来获取软件包名称和体系结构，但是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

解决方法

这里有两种方法。

一种方法是使用array_map使用explode（可以改为使用普通的foreach），另一种方法是使用正则表达式。

<?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);

两者都会产生相同的结果：
