php - 检查多维数组中的键值对

Question

我有以下数组:

Array
(
    [0] => Array
        (
            [type] => foo
        )

    [1] => Array
        (
            [type] => bar
        )

    [2] => Array
        (
            [type] => bar
        )
)

并且需要知道是否存在一个或多个type，其值为bar，不这样做:

foreach ($arrayOfTypes as $type) {
    if ($type['type'] == 'bar')
    {
        // Stuff here
    }
}

(仅供学习)

Answer 1

我会选择 array_filter() ;

$filteredArray = array_filter($stuff, function($item){

    return $item['type'] == 'bar';

});

if( count($filteredArray) > 0 ){

    echo 'There was a bar item in array.';

}else{

    echo 'No luck sorry!';

}
