搜索数组并返回所有键和值，当找到匹配 [英] Search array and return all keys and values when match found

问题描述

我想执行一个阵列上搜索，当发现匹配返回的所有值。数组中的键 [名] 是我在做什么上进行搜索。

 阵列（
[0] =＆GT;排列
    （
        [ID] =＆GT; 20120100
        [链接] =＆GT; www.janedoe.com
        [名] =＆GT;李四
    ）
[1] =＆GT;排列
    （
        [ID] =＆GT; 20120101
        [链接] =＆GT; www.johndoe.com
        [名] =＆GT;李四
    ）
）
 

如果我做了一个搜索李四它会返回。

 阵列
（
    [ID] =＆GT; 20120101
    [链接] =＆GT; www.johndoe.com
    [名] =＆GT;李四
）
 

它会更容易重新命名根据我所寻找的阵列。相反，上述阵列我也可以生成以下。

 阵列（
[李四] =＆GT;排列
    （
        [ID] =＆GT; 20120100
        [链接] =＆GT; www.janedoe.com
        [名] =＆GT;李四
    ）
[李四] =＆GT;排列
    （
        [ID] =＆GT; 20120101
        [链接] =＆GT; www.johndoe.com
        [名] =＆GT;李四
    ）
）
 

解决方案

  $ filteredArray =
array_filter（$阵列功能（$元素）使用（$ searchFor）{
  返回使用isset（$元素['名']）及和放大器; $元素[名称] == $ searchFor;
}）;
 

需要PHP 5.3.x

I like to perform a search on an array and return all values when a match is found. The key [name] in the array is what I am doing a search on.

Array (
[0] => Array
    (
        [id] => 20120100
        [link] => www.janedoe.com
        [name] => Jane Doe
    )
[1] => Array
    (
        [id] => 20120101
        [link] => www.johndoe.com
        [name] => John Doe
    )
)

If I did a search for John Doe it would return.

Array
(
    [id] => 20120101
    [link] => www.johndoe.com
    [name] => John Doe
)

Would it be easier to rename the arrays based on what I am searching for. Instead of the above array I can also generate the following.

Array (
[Jane Doe] => Array
    (
        [id] => 20120100
        [link] => www.janedoe.com
        [name] => Jane Doe
    )
[John Doe] => Array
    (
        [id] => 20120101
        [link] => www.johndoe.com
        [name] => John Doe
    )
)

解决方案

$filteredArray = 
array_filter($array, function($element) use($searchFor){
  return isset($element['name']) && $element['name'] == $searchFor;
});
