Converting a PHP timestamp to a date(time)

In this PHP tutorial, we’re going to convert a timestamp in PHP to a date (optionally with time) using custom formatting. We’ll start by getting the current time stamp and display it using the simple date function. Next, we’ll use the current timestamp to create a Date Time object, format the date and display it. We’ll then view some of the date and time formatting options, followed by the Date Time Zone class. And finally, we’ll create a function to convert a timestamp to DateTime with time zone and date format parameters.

Getting a Timestamp

Let’s start with a basic PHP function to get the timestamp, we’ll use time() to get the current timestamp and date to format the output.

The time stamp saved in $now is similar to 1610246191, so we format it using date(‘Y-m-d’, $now) for a user friendly output. The timestamp returned is in seconds, see the microtime function to get a timestamp including micro seconds.

Timestamp To Date Time Object

While we can use the date function to format our date or timestamp, it isn’t the object oriented way of doing it. Let’s create a DateTime object and set the timestamp.

We can then output the date and time using the format method with the ‘c’ datetime parameter.

Formatting a Date

The format method can format a date in many different ways, common formats are: Y-m-d and d/m/Y .

The PHP manual has many more date formats available.

Formatting a Time

The DateTime class can also format the same timestamp in time only format.

We use the H:i:s(Hour, Minute, Second) format in the code above.

Date with TimeZone

The DateTime object can be set to use a specific time zone. We create a new DateTimeZone with a particular time zone and call the setTimeZone method on our DateTime object.

The DateTimeZone class has many timezone options. The PHP code example above displays the same timestamp using different time zones.

Converting a Timestamp to Date Time

Our final function is a combination of DateTime and DateTimeZone with 3 parameters: a timestamp, time zone and date/time format with default formatting.

Our custom PHP function timeStampToDateTime takes a timestamp as first parameter, which could be the current timestamp or any other time stamp (maybe a timestamp from a db). It uses the timezone and format to return a human readable date time string.

Key Takeaways

We can use the time() function to get the current timestamp and the date function to format a timestamp.
The DateTime class is the object oriented way of working with dates and times.
The DateTimeZone class provides time zone functionality which can be used with the DateTime class to work with dates and times.
The format , setTimeZone and setTimeStamp methods are the primary methods we can use to convert a timestamp to date/time.

Convert One Date Format to Another in PHP

Use date() and strtotime() Functions to Convert One Date Format to Another in PHP
Use createFromFormat() and format() Functions to Convert One Date Format to Another in PHP

In this article, we will introduce methods to convert one Date format to another in PHP.

Use date() and strtotime() Functions to Convert One Date Format to Another in PHP

The date() function converts a timestamp to a date . The correct syntax to use this function is as follows

$format is the specific format in which the date is converted.

$timestamp is an optional parameter. It gives the date according to the timestamp passed. If it omitted, then we will get the current date .

The function strtotime() is a built-in function in PHP. This function converts a date to the time. The correct syntax to use this function is as follows.

strtotime($dateString, $timeNow);

$dateString is a mandatory parameter, and it is the string representation of a date.

$timeNow is an optional parameter. It is the timestamp that is used for calculating relative dates.

php $originalDate = "2020-04-29"; //original date is in format YYYY-mm-dd  $timestamp = strtotime($originalDate); $newDate = date("m-d-Y", $timestamp ); echo "The new date is $newDate."; ?>

We have used date() and strtotime() function to convert one date format to another. The function strtotime() has converted the original date to a timestamp. This timestamp is then converted to date of the required format using date() function.

Use createFromFormat() and format() Functions to Convert One Date Format to Another in PHP

The function createFromFormat() is a built-in function in PHP. This function converts a timestamp or date string to a DateTime object. The correct syntax to use this function is as follows.

DateTime::createFromFormat($format, $time, $timezone);

The variable $format is the format of the date, $time is the time or date given in string, and $timezone gives the time zone. The first two parameters are the mandatory parameters.

The format() function is used to format a date to the required format. The correct syntax to use this function is

$datetimeObject->format($formatString);

The parameter $formatString specifies the required format.

php $originalDate = "2020-04-29"; //original date is in format YYYY-mm-dd  $DateTime = DateTime::createFromFormat('Y-m-d', $originalDate); $newDate = $DateTime->format('m-d-Y'); echo "The new date is $newDate."; ?>

Here, we have created a DateTime object using createFromFormat() function. The DateTime object then calls the format() function to convert one date format to another.

Convert a Timestamp to a Readable Date or Time in PHP

In this article, we will introduce methods to convert a timestamp to date in PHP.

Using createFromFormat() function

Use date() Function to Convert a Timestamp to a Date/Time in PHP

The date() function converts a timestamp to a human readable date or time . The correct syntax to use this function is as follows

It has two parameters. The parameter $format is the date-time format that the timestamp is converted to. The other parameter $timestamp is an optional parameter. It gives the date according to the timestamp passed. If it is omitted, it uses the current date by default.

php $date = date('d-m-Y H:i:s', 1565600000); echo "The date is $date."; ?>

The date format here is day-month-year , and the time format is hour:minute:second .

The date and time are 12-08-2019 08:53:20.

Use setTimestamp() Function to Convert a Timestamp to a Date in PHP

The built-in setTimestamp() converts the given timestamp to date or time . To set the format of the date we will use format() function.

$datetimeObject->setTimestamp($timestamp);

php $date = new DateTime(); $date->setTimestamp(1565600000); $variable = $date->format('U = d-m-Y H:i:s'); echo "The date and time is $variable."; ?>

The date and time are 1565600000 = 12-08-2019 08:53:20.

Use createFromFormat() Function to Convert a Timestamp to a Date in PHP

The built-in function createFromFormat() gets the date by passing the timestamp as a parameter to this function.

DateTime::createFromFormat($format, $time, $timezone);

The variable $format is the format of the date, $time is the time given in string and $timezone tells about the time zone. The first two parameters are the mandatory parameters.

php // Calling the createFromFormat() function  $datetime = DateTime::createFromFormat('U', '1565600000'); // Getting the new formatted datetime  $date= $datetime->format('d-m-Y H:i:s'); echo "The date and time is $date."; ?>

The format «d-m-Y H:i:s» displays both date and time .

The date and time are 12-08-2019 08:53:20.
