Php 如何在多维数组中找到相同的值

我需要你的帮助，我有一个数组如下

[["A","Orange"],["B","Orange"],["C","Orange"],["D","Orange"],["E","Apple"],["F","Mango"],["G","Banana"]]

我想找到同样的水果，这样结果会更好

A - D: Orange, E: Apple, F: mango, G Banana

---

如何在多数组中搜索相同的水果？谢谢。

将水果名称用作键，并将键用作结果的值

foreach($fruits as $fruit)
{
  $o[$fruit[1]][] = $fruit[0];
}

测试代码：

<?php
$fruits = [["A","Orange"],["B","Orange"],["C","Orange"],["D","Orange"],["E","Apple"],["F","Mango"],["G","Banana"]];
foreach($fruits as $fruit)
{
  $o[$fruit[1]][] = $fruit[0];
}
var_dump($o);

编辑：

<?php
$fruits = [["A","Orange"],["B","Orange"],["C","Orange"],["D","Orange"],["E","Apple"],["F","Mango"],["G","Banana"]];
$fruits2 = [["A","Orange"],["C","Orange"],["D","Orange"],["E","Apple"],["F","Mango"],["G","Banana"]];
foreach($fruits2 as $fruit)
{
  $o[$fruit[1]][] = $fruit[0];
}
$o = array_map(function($v){
  $str = '';
  $pre = '';
  $isInSequence = false;
  $item = '';
  foreach($v as $item)
  {
    if($pre != '')
    {
        if(ord($pre) == ord($item) - 1)
        {
            $isInSequence = true;
        }
        else
        {
            if($isInSequence)
                $str = $str . '-';
            else
                $str = $str . ',' . $item;
            $isInSequence = false;
        }
    }
    else
        $str = $str.$item;
    $pre = $item;
  }
  if($isInSequence)
  {
      $str = $str . '-' . $item;
  }
  return $str;
}, $o);
var_dump($o);

创建一个

foreach

loop我已经创建了一个，但是我一直想知道如何匹配同一个水果的名字@如果数组中不存在名称，可以将其添加到数组中。可以给我举个例子吗？我不明白，长官@u_mulderu做不到，这是非法的偏移量类型怎么会是长官？我的意思是，数组会自动找到它吗？请向我解释一下，先生，我是如何表示结果的？A-d:橙色，E:苹果，F:芒果，G香蕉是的，当复制值键按顺序排列时，很容易。但当复制品按顺序进行时，输出应该是什么？非常感谢，先生，它解决了我的问题：D:D#补充道

<?php
$fruits = [["A","Orange"],["B","Orange"],["C","Orange"],["D","Orange"],["E","Apple"],["F","Mango"],["G","Banana"]];
$fruits2 = [["A","Orange"],["C","Orange"],["D","Orange"],["E","Apple"],["F","Mango"],["G","Banana"]];
foreach($fruits2 as $fruit)
{
  $o[$fruit[1]][] = $fruit[0];
}
$o = array_map(function($v){
  $str = '';
  $pre = '';
  $isInSequence = false;
  $item = '';
  foreach($v as $item)
  {
    if($pre != '')
    {
        if(ord($pre) == ord($item) - 1)
        {
            $isInSequence = true;
        }
        else
        {
            if($isInSequence)
                $str = $str . '-';
            else
                $str = $str . ',' . $item;
            $isInSequence = false;
        }
    }
    else
        $str = $str.$item;
    $pre = $item;
  }
  if($isInSequence)
  {
      $str = $str . '-' . $item;
  }
  return $str;
}, $o);
var_dump($o);
