php 2 D配列はフィールドでソートされます

主に2つの関数を使用します.
1.array_column()は、入力配列の単一カラムの値を返します.phpバージョン5.5以降持参
2.array_Multisort()関数は、ソート配列を返します.1つ以上の配列を入力できます.関数は、最初の配列をソートし、次に他の配列をソートします.2つ以上の値が同じ場合、次の配列をソートします.

php
$data = [[
    "path" => "sftp/outgoing/1234_20200201_bill(1).csv",
    "timestamp" => 1591669515,
    "type" => "file",
    "visibility" => "public",
    "size" => 765,
    "dirname" => "sftp/outgoing",
    "basename" => "1234_20200201_bill(1).csv",
    "extension" => "csv",
    "filename" => "1234_20210201_bill(1)",
], [
    "path" => "sftp/outgoing/1234_20200611_bill.csv",
    "timestamp" => 1591937136,
    "type" => "file",
    "visibility" => "public",
    "size" => 240,
    "dirname" => "sftp/outgoing",
    "basename" => "1234_20200611_bill.csv",
    "extension" => "csv",
    "filename" => "1234_20200611_bill",
]];
$last_names = array_column($data, 'filename');
array_multisort($last_names, SORT_ASC, $data);//SORT_ASC         ， SORT_DESC         

echo '
';
print_r($data);
echo '
';
exit;
