How to filter a two dimensional array by value
提问by aphextwix
How would I create a function that filters a two dimensional array by value?
我将如何创建一个按值过滤二维数组的函数？
Given the following array :
给定以下数组：
Array
(
[0] => Array
(
[interval] => 2014-10-26
[leads] => 0
[name] => CarEnquiry
[status] => NEW
[appointment] => 0
)
[1] => Array
(
[interval] => 2014-10-26
[leads] => 0
[name] => CarEnquiry
[status] => CALL1
[appointment] => 0
)
[2] => Array
(
[interval] => 2014-10-26
[leads] => 0
[name] => Finance
[status] => CALL2
[appointment] => 0
)
[3] => Array
(
[interval] => 2014-10-26
[leads] => 0
[name] => Partex
[status] => CALL3
[appointment] => 0
)
How would I filter the array to only show those arrays that contain a specific value in the namekey? For example name = 'CarEnquiry'.
我将如何过滤数组以仅显示那些包含name键中特定值的数组？例如name = 'CarEnquiry'。
The resulting output would be:
结果输出将是：
Array
(
[0] => Array
(
[interval] => 2014-10-26
[leads] => 0
[name] => CarEnquiry
[status] => NEW
[appointment] => 0
)
[1] => Array
(
[interval] => 2014-10-26
[leads] => 0
[name] => CarEnquiry
[status] => CALL1
[appointment] => 0
)
)
EDIT
编辑
I forgot to mention that the search value should be interchangeable - i.e. name = 'CarEnquiry'or name = 'Finance'.
我忘了提到搜索值应该是可互换的 - 即name = 'CarEnquiry'或name = 'Finance'.

Use PHP's array_filterfunction with a callback.
将 PHP 的array_filter函数与回调一起使用。
$new = array_filter($arr, function ($var) {
return ($var['name'] == 'CarEnquiry');
});
Edit: If it needs to be interchangeable, you can modify the code slightly:
编辑：如果需要互换，可以稍微修改一下代码：
$filterBy = 'CarEnquiry'; // or Finance etc.
$new = array_filter($arr, function ($var) use ($filterBy) {
return ($var['name'] == $filterBy);
});

If you want to make this a generic function use this:
如果您想让它成为通用函数，请使用以下命令：
function filterArrayByKeyValue($array, $key, $keyValue)
{
return array_filter($array, function($value) use ($key, $keyValue) {
return $value[$key] == $keyValue;
});
}

array_filteris the function you need. http://php.net/manual/en/function.array-filter.php
array_filter是你需要的功能。http://php.net/manual/en/function.array-filter.php
Give it a filtering function like this:
给它一个这样的过滤功能：
function my_filter($elt) {
return $elt['name'] == 'something';
}

<?php
function filter_array($array,$term){
$matches = array();
foreach($array as $a){
if($a['name'] == $term)
$matches[]=$a;
}
return $matches;
}
$new_array = filter_array($your_array,'CarEnquiry');
?>

function multi_array_search_with_condition($array, $condition)
{
$foundItems = array();
foreach($array as $item)
{
$find = TRUE;
foreach($condition as $key => $value)
{
if(isset($item[$key]) && $item[$key] == $value)
{
$find = TRUE;
} else {
$find = FALSE;
}
}
if($find)
{
array_push($foundItems, $item);
}
}
return $foundItems;
}
This my function can use about this problem. You can use:
这个我的函数可以用来解决这个问题。您可以使用：
$filtered = multi_array_search_with_condition(
$array,
array('name' => 'CarEnquiry')
);
This will get your filtered items from your 2 dimensional array.
这将从您的二维数组中获取您的过滤项目。

Above examples are using the exact word match, here is a simple example for filtering array to find imprecise "name" match.
上面的例子是使用精确的词匹配，这里是一个简单的例子，用于过滤数组以找到不精确的“名称”匹配。
$options = array_filter($options, function ($option) use ($name) {
return strpos(strtolower($option['text']), strtolower($name)) !== FALSE;
});
