Q: Convert 1687449600000 to 2023-06-23 format
Answer: To convert 1687449600000 to 2023-06-23 format, you need to convert the timestamp into a date format, and then format it according to the specified format.
First, convert the timestamp to a date format:
Timestamp: 1687449600000
Unit: milliseconds
In PHP, in the Laravel framework, you can use the Carbon extension to handle dates and times. Below is the sample code to convert timestamp 1687449600000 to '2023-06-23' format:
First, make sure you have the Carbon extension installed. Composer can be used to install:
composer require nesbot/carbon
Then, where you need to convert the timestamp, you can use the following code:
phpuse Carbon\Carbon;
$timestamp = 1687449600000 / 1000; // 将毫秒转换为秒
$date = Carbon::createFromTimestamp($timestamp)->format('Y-m-d');
In the above code, createFromTimestamp()the timestamp is converted to a Carbon instance by using the Carbon method. Then using format()the method, format the date in 'Ymd' format.
Finally, $datethe value of the variable is '2023-06-23', i.e. convert the timestamp 1687449600000 to '2023-06-23' format.
Make sure you have imported the Carbon class at the beginning of the file:
phpuse Carbon\Carbon;
Q: Why is one day missing after conversion
A: Sorry to cause you confusion. When using Carbon for date conversion in the Laravel framework, time zone issues may cause date deviations. To fix this, you can set the correct timezone before converting.
In Laravel framework, options can config/app.phpbe found in files timezone. Make sure this option is set to the correct time zone for your location. For example, if you are in China, you can set it to 'Asia/Shanghai'.
php'timezone' => 'Asia/Shanghai',
Then, rerun your code for date conversion. That way, you should be able to convert the timestamp correctly and get the correct date.
