Tips

array_column函数

array_column():第二个参数为null,指定第二维数组里的键为第三个参数,可以提取该键对应的值为一维的键值

$arr = [
    ['id'=>'a','name'=>'A'],
    ['id'=>'b','name'=>'B'],
    ['id'=>'c','name'=>'C']
];
$res = array_column($arr,null,'id');
/*
 $res = [
    'a'=>['id'=>'a','name'=>'A'],
    'b'=>['id'=>'b','name'=>'B'],
    'c'=>['id'=>'c','name'=>'C']
];
*/

php和java的哈希macSha256加密

Mac mac = Mac.getInstance("HmacSHA256");
SecretKeySpec signingKey = new SecretKeySpec(appSecret.getBytes(), "HmacSHA256");
mac.init(signingKey);
byte[] signData = mac.doFinal(encodedStr.getBytes());
byte[] resultBytes = Base64.getEncoder().encode(signData);
signatureResult = new String(resultBytes, "UTF-8");

base64_encode(hash_hmac('sha256', $str, $this->appSecret, true))

查看php.ini的文件位置
