Example showing how to convert JS timestamp to PHP timestamp

JavaScript and PHP are two different programming languages, and they have some differences in timestamp processing. In JavaScript, a timestamp refers to the number of milliseconds since January 1, 1970 00:00:00 UTC, while in PHP a timestamp refers to the number of milliseconds since January 1, 1970 00:00:00 UTC seconds.

So when we need to generate a timestamp in JavaScript and pass it to PHP, we need to do some additional conversions. In this article, I will show you how to convert JavaScript timestamps to PHP timestamps.

The first step is to generate the timestamp in JavaScript. To do this, we can use the getTime() method of the Date object in JavaScript. The getTime() method returns the number of milliseconds since January 1, 1970 00:00:00 UTC.

Here is a sample JavaScript function that converts the current time to a timestamp:

function getTimestamp() {
    return new Date().getTime();
}

Next, we need to convert the JavaScript timestamp to a PHP timestamp. To do this we need to use the date() function in PHP. The date() function accepts two parameters - the first parameter is a format string that specifies the format of the output date/time, while the second parameter is a timestamp, which can be a Unix timestamp or a date from 1970 The number of seconds since 00:00:00 UTC on the 1st of the month.

The following is a sample PHP code snippet that converts a JavaScript timestamp to a PHP timestamp:

$javascript_timestamp = 1622260152195; // JavaScript时间戳

$php_timestamp = floor($javascript_timestamp / 1000); // 转换为秒数

echo date('Y-m-d H:i:s', $php_timestamp); // 输出格式化的日期/时间

In the above example, we first divide the JavaScript timestamp by 1000 to convert Convert milliseconds to seconds. We then pass the result to the date() function to produce a date/time output in a standard format.

In this article, I show you how to convert JavaScript timestamps to PHP timestamps. Remember that the JavaScript timestamp must be converted to a Unix timestamp in seconds before passing it to PHP. Hope this article helps you!
