Laravel 8 diffAssoc() {#collection-method}

2021-07-01 14:28:55 更新

diffAssoc 方法与另外一个集合或基于 PHP 数组的键 / 值对进行比较。这个方法将会返回原集合不存在于指定集合的键 / 值对:


$collection = collect([
    'color' => 'orange',
    'type' => 'fruit',
    'remain' => 6,
]);

$diff = $collection->diffAssoc([
    'color' => 'yellow',
    'type' => 'fruit',
    'remain' => 3,
    'used' => 6,
]);

$diff->all();

// ['color' => 'orange', 'remain' => 6]
