使用 PHP 将时间戳以毫秒为单位插入 Postgres 表

Question

I have a Postgres table, like so:

create table test
    (
        time_stamp timestamp
    );

I want to generate a string with PHP that will insert the current time, with milliseconds (or microseconds) into the table.

Based on some other research, I've tried inserting the results of:

date('Y-m-d H:i:s.u', time())

But I'm only getting seconds. Any ideas?

Answer 1

Or u can use date:

list($usec, $sec) = explode(' ', microtime()); 
$usec = str_replace("0.", ".", $usec);
print date('H:i:s', $sec) . $usec;       

Answer 2

I had assumed there was an easy way to do this in PHP, but apparently there's not. Here's the solution:

function get_time() {
    $time = microtime(true);
    $micro_time = sprintf("%06d", ($time - floor($time)) * 1e6);
    return date('Y-m-d H:i:s.', $time).$micro_time;
}

Answer 3

I'm using date_create [1] from class datetime [2]

$dt1 = date_create();
echo $dt1->format('Y-m-d H:i:s.u');
