根据字符串中包含的单词对数组进行排序-解网

问：

我见过很多对数组进行排序的例子，包括 DESC 和 ASC、字母顺序等等，但我没有找到任何可以帮助我的情况。我有一组大型数组，我只展示其中的重要部分。以下是数组：

[0] => Array
        (
            [articleID] => 3166
            [articleName] => Drum Kit MultiPack 
        )

[1] => Array
        (
            [articleID] => 2073
            [articleName] => Toner black TN-241BK 
        )

[2] => Array
        (
            [articleID] => 3241
            [articleName] => Toner black TN-241BK 
        )

[3] => Array
        (
            [articleID] => 3242
            [articleName] => Original Kit colour 
        )

我想做的是首先显示字符串中包含“Toner”的 articleName 数组（优先级 0），然后在“Toner”（优先级 1）之后显示具有“Drum kit”的 articleName，然后是“Original”（优先级 2）

我真的尝试了很多不同的代码，但没有一个有帮助。这是我能提供的，将有助于你的理解。

public function indexAction()
    {
    $products = array() // this variable contains all the original arrays that i showed above.
    $priorities = array('Toner'=>0,'Drum Kit'=>1,'Original'=> 2); //$products array should be set to these priorities

    function sorting ($a, $b) { 
    //magic code
       }

    uasort($products, 'sorting');
    print_r( $products);

    }



   the outcome should look like:

    [0] => Array
            (
                [articleID] => 2073
                [articleName] => Toner black TN-241BK 
            )
    
    [1] => Array
            (
                [articleID] => 3241
                [articleName] => Toner black TN-361MK 
            )
   [2] => Array
            (
                [articleID] => 3166
                [articleName] => Drum Kit MultiPack 
            )
    
    [3] => Array
            (
                [articleID] => 3242
                [articleName] => Original Kit colour 
            )

更新：我写了这个：

usort($products, function ($a, $b) {
$productArray = array('Toner Black TN-241BK'=>0,'Drum Kit MultiPack'=>1,'Original Kit colour'=> 2);

return $productArray[$a['articleName']] <=> $productArray[$b['articleName']];

 });

它有效。

php 排序

我是这样写的： ' usort（$products， function （$a， $b） { $productArray = array（'Toner Black TN-241BK'=>0，'Drum Kit MultiPack'=>1，'Original Kit colour'=> 2）; return $productArray[$a['articleName']] <=> $productArray[$b['articleName']]; }）;' 它就像我想要的一样工作，但是，并非每个碳粉黑都有相同的挖掘，我该如何制作它，以便它只寻找字符串是否存在？如何插入正则表达式？preg_match（“/碳粉/”， $products）

“how can i insert a RegEx” - 你不能将正则表达式“插入”到那种数组中。您需要分别确定这两个项目的此 0/1/2 值。

<?php

// Text to be match => order
$sortOrders = [
  'Toner' => 1,
  'Drum Kit' => 2,
  'Original' => 3
];

// Data collection
$data = [
  [
      'articleID' => 3166,
      'articleName' => 'Drum Kit MultiPack' 
  ],
  [
      'articleID' => 2073,
      'articleName' => 'Toner black TN-241BK'
  ],
  [
      'articleID' => 3241,
      'articleName' => 'Toner black TN-241BK'
  ],
  [
      'articleID' => 3242,
      'articleName' => 'Original Kit colour'
  ]
];

usort($data, function($data1, $data2) use($sortOrders){

  foreach( $sortOrders as $key => $sortOrder ){

    // Determine sort order
    if (strpos($data1['articleName'], $key) !== false) {
      $orderForData1 = $sortOrder;
    }
    if (strpos($data2['articleName'], $key) !== false) {
      $orderForData2 = $sortOrder;
    }

  }
  return $orderForData1 <=> $orderForData2;

});

print_r($data);

输出：

Array
(
    [0] => Array
        (
            [articleID] => 3241
            [articleName] => Toner black TN-241BK
        )

    [1] => Array
        (
            [articleID] => 2073
            [articleName] => Toner black TN-241BK
        )

    [2] => Array
        (
            [articleID] => 3166
            [articleName] => Drum Kit MultiPack
        )

    [3] => Array
        (
            [articleID] => 3242
            [articleName] => Original Kit colour
        )

)
