How to get the current time in php

In PHP, a common way to get the time is to use PHP's built-in time function. Among them, the most commonly used are the date() function and time() function. These two functions can help us easily obtain the current time, or convert the timestamp into a date and time string.

So, what are the most appropriate points in PHP? It depends on your specific needs. If you only need to get the current hour, you can use the date('H') function to get it. This function returns the hour part of the current time, using the 24-hour clock, which is an integer between 0 and 23.

The following is an example:

$hour = date('H');
echo "当前时间的小时数是： $hour";

The output may be like this:

当前时间的小时数是： 14

If you need to get the current minutes, you can also use the date() function, just Just replace 'H' with 'i'. This function returns the minute part of the current time, using an integer between 00 and 59.

The following is an example:

$minute = date('i');
echo "当前时间的分钟数是： $minute";

The output may look like this:

当前时间的分钟数是： 37

It should be noted that the date() function returns the current server time, not Browser side time. If your server is located abroad, the time you obtain may be very different from the local time. Therefore, if you need to obtain the user's local time, you should use client-side technologies such as JavaScript to achieve this.

In addition, if you need to get the timestamp of the current time, you can use the time() function. This function returns the number of seconds from the current time to 00:00:00 GMT on January 1, 1970. You can pass it as a parameter to the date() function to obtain more detailed time information.

The following is an example:

$timestamp = time();
$date = date('Y-m-d H:i:s', $timestamp);
echo "当前时间是: $date";

The output result may be like this:

当前时间是： 2022-05-01 14:55:32

In summary, getting time in PHP mainly uses the date() function and time() function to implement. Which point is most appropriate depends on your specific needs. It should be noted that the time obtained is the server time, not the client time. If you need to obtain the local time, you should use client-side technologies such as JavaScript to achieve it.
