PHP:基于值分离数组

我有以下数组:

$raw = [
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'used'
    ],
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'used'
    ],
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'used'
    ],
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'used'
    ],
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'used'
    ],
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'new'
    ],
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'new'
    ],
    [
        'prop1' => 'somevalue',
        'prop2' => 'anothervalue',
        'path' => 'new'
    ],
];

我需要过滤这个数组,最好使用filter_array保持代码更清洁,我需要根据path属性进行过滤.所以我最终会:

$filtered = [
    'used' => [
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'used'
        ],
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'used'
        ],
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'used'
        ],
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'used'
        ],
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'used'
        ]
    ],
    'new' => [
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'new'
        ],
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'new'
        ],
        [
            'prop1' => 'somevalue',
            'prop2' => 'anothervalue',
            'path' => 'new'
        ]
    ]
];
