如何在php中为json数组创建搜索函数

$json = '[{"name":"John","age":30},{"name":"Jane","age":25},{"name":"Bob","age":35}]';
$array = json_decode($json, true);

function searchArray($keyword, $array) {
    $results = array();
    foreach ($array as $item) {
        if (strpos($item['name'], $keyword) !== false) {
            $results[] = $item;
        }
    }
    return $results;
}

$results = searchArray('John', $array);
print_r($results);

Array
(
    [0] => Array
        (
            [name] => John
            [age] => 30
        )
)
