我想使用 PHP pg_query_params 方法将 unix 时间戳值插入 postgres 时间戳列,但被卡住了。

这是不完整的代码:

$con = pg_connect(...);
$stmt = 'INSERT INTO my_table (submitted) VALUES ($1)';
$ts = 1479939387;
$values = [translate_timestamp_into_sth_postgres_accepts($ts)];
$res = pg_query_params($con, $stmt, $values);

问:如何将 unix seconds 值转换为 sth。postgres 接受吗?

使用功能to_timestamp(double precision)

select to_timestamp(1479939387) at time zone 'utc' as tstamp;

       tstamp

您的代码可能如下所示(使用默认时区):

$con = pg_connect(...);
$stmt = 'INSERT INTO my_table (submitted) VALUES (to_timestamp($1))';
$ts = 1479939387;
$res = pg_query_params($con, $stmt, $ts);
