Teach you step by step how to convert PHP timestamp to regular time format

In PHP development, we often need to obtain the current time and format the output. In actual development, we usually use timestamps to represent time, which is both convenient and effective. However, as time passes, we sometimes need to convert the timestamp into a regular time format, such as year-month-day hour:minute:second. In this case, we can use PHP’s built-in functions to achieve this goal. Below, we will teach you step by step how to convert timestamp to regular time format using PHP.

Step 1: Get the timestamp

In PHP, we can use the function time() to get the timestamp of the current time, which returns the current time since the Unix epoch , in seconds. We can use the following code to obtain the timestamp:

$timestamp= time();

Step 2: Convert the timestamp to regular time format

After obtaining the timestamp, we need to use the date() function to convert the timestamp In regular time format. The date() function receives two parameters. The first parameter is the time format we want to output, and the second parameter is the timestamp. The following is a sample code:

$timestamp = time();
$date_time = date("Y-m-d H:i:s", $timestamp);
echo $date_time;

After running the code, we will output a regular time format, as shown below:

2022-01-01 01:01:01

In the above code, we use the date() function to convert the timestamp Convert to regular time format, where "Y-m-d H:i:s" represents the time format, where Y represents the year, m represents the month, d represents the date, H represents the hour, i represents the minute, and s represents the second.

Step 3: Convert regular time format to timestamp

In contrast to converting timestamp to regular time format, we can also convert regular time format to timestamp. In PHP we can convert regular time format to timestamp using strtotime() function. Here is a sample code:

$date_time = "2022-01-01 01:01:01";
$timestamp = strtotime($date_time);
echo $timestamp;

After running the code, the following timestamp will be output:

1640989261

In the above sample code, we use the strtotime() function to convert the regular time format "2022- 01-01 01:01:01" converted to timestamp.

Summary

In PHP development, timestamps and regular time formats are both very important knowledge points. We can easily convert timestamp to regular time format and regular time format to timestamp using PHP's built-in functions time() and date(). Hopefully, through this article, you have mastered how to convert timestamp to regular time format using PHP.
