In PHP, you can easily convert the current timestamp into a readable time format. A timestamp is the number of seconds since January 1, 1970 00:00:00 UTC to the current time, expressed as an integer. You can use the time() function in PHP to get the current timestamp. Let's take a look at how to convert the current timestamp into a readable time format.

Using the date() function

In PHP, you can use the date() function to convert a timestamp into a specified date format. The syntax of this function is as follows:

string date ( string $format [, int $timestamp = time() ] )
Copy after login

Among them, the $format parameter is the specified date format, and the $timestamp parameter is the timestamp. If the $timestamp parameter is not specified, the current timestamp is used by default.

The following are some common date format codes:

Code Description
Y 4 digits for year
m 2 digits for month
d 2-digit date
H Hour in 24-hour format
i Minutes
s Seconds
##Here is a simple example:

$timestamp = time();
echo date('Y-m-d H:i:s', $timestamp);
Copy after login
This code will output the year, month, date, hour, minutes and seconds of the current time. For example: 2021-11-05 09:30:25.

Using the DateTime class

In addition to using the date() function, you can also use the DateTime class provided by PHP to convert timestamps into date format. This class provides many methods to handle dates and times, and can easily convert dates in different formats.

Here is an example:

$timestamp = time();
$datetime = new DateTime();
$datetime->setTimestamp($timestamp);
echo $datetime->format('Y-m-d H:i:s');
Copy after login
The code is similar to the previous example, but uses the DateTime class for the conversion. It should be noted that the DateTime class uses method chaining, and the setTimestamp() and format() methods can be called directly after instantiation.

Summary

The above are two ways to use PHP to convert the current timestamp into date format: using the date() function and using the DateTime class. In actual use, you can choose one of the methods for conversion according to specific needs. At the same time, you need to pay attention to the impact of time zone. You can use the date_default_timezone_set() function to set the time zone.
