使用php分析能力搜索

Question

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

我想做的是(使用php(将packaga name、the architecture(位于/之后(和description of the package(位于包和体系结构的行下方(分离，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：

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

我可以在/上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

感谢您的帮助！

更新：

我可以使用"爆炸"来获得包名称和体系结构/"但是我不知道怎么才能拿到下面的那条线。我想我可以找到一个漂亮的解决方案

这里有几种方法

一种方法是使用带有array_map的爆炸(您可以使用普通foreach(，另一种方法使用regex。

<?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("nr", $str));

或者使用regex、

preg_match_all('#(?<package>.*?)/(?<distro>.*?) (?<version>.*?) (?<arch>.*?)n  (?<desc>.*?)nr#', $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：
