How to filter a two dimensional array by value

Question

Use PHP's array_filter function with a callback.

$new = array_filter($arr, function ($var) {
    return ($var['name'] == 'CarEnquiry');
});

Edit: If it needs to be interchangeable, you can modify the code slightly:

$filterBy = 'CarEnquiry'; // or Finance etc.

$new = array_filter($arr, function ($var) use ($filterBy) {
    return ($var['name'] == $filterBy);
});

<?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');

?>

If you want to make this a generic function use this:

function filterArrayByKeyValue($array, $key, $keyValue)
{
    return array_filter($array, function($value) use ($key, $keyValue) {
       return $value[$key] == $keyValue; 
    });
}

Above examples are using the exact word match, here is a simple example for filtering array to find imprecise "name" match.

  $options = array_filter($options, function ($option) use ($name) {
    return strpos(strtolower($option['text']), strtolower($name)) !== FALSE;
  });

array_filter is the function you need. http://php.net/manual/en/function.array-filter.php

Give it a filtering function like this:

function my_filter($elt) {
    return $elt['name'] == 'something';
}
