PHP date_time_set() Function


Hello dear readers! welcome back to another edition of our tutorial on PHP. In this tutorial guide, we are going to be discussing about the PHP date_time_set() Function.

The PHP date_time_set() function is an alias of DateTime::setTime() function. Using this, you can reset the time of a DateTime object.

Syntax

Following below is the syntax to use this function -

date_time_set($object, $hours, $minutes, $seconds, $microseconds)


Parameter Details

Sr.NoParameter & Description
1

object(Mandatory)

This is a DateTime object to which you need to set the date.

2

hours(Mandatory)

This is an integer value representing the hour of the time to be set.

3

minute(Mandatory)

This is an integer value representing the minute of the time to be set.

4

seconds(Optional)

This is an integer value representing the seconds of the time to be set.

5

microseconds(Optional)

This is an integer value representing the microseconds of the time to be set.


Return Value

This built-in PHP function returns the DateTime object with modified (time) value. Incase of failure, this function returns FALSE.

PHP Version

This function was first introduced as part of core PHP v 5.2.0 and, it works with all the later versions.

Example1

Following example illustrates the usage of the PHP date_time_set() function -

<?php
   //Creating a date
   $date = new DateTime();
   //Setting the date
   date_time_set($date, 7, 20, 35);   
   print("Date: ".date_format($date, "Y/m/d H:i:s"));
?>

Output

When the above code is executed, it will produce the following result -

Date: 2020/05/10 07:20:35

Example2

The following example creates a DateTime object and modifies its value by using the date_time_set() function -

<?php
   //Date string
   $date_string = "25-09-1989 10:42:12";
   //Creating a DateTime object
   $date_time_Obj = date_create($date_string);
   print("Original Date: ".date_format($date_time_Obj, "Y/m/d H:i:s"));
   print("\n");
   //Setting the date
   $date = date_time_set($date_time_Obj, 6, 36, 3 );   
   print("Modified Date: ".date_format($date, "Y/m/d H:i:s"));
?>

Output

When the above code is executed, it will produce the following result -

Original Date: 1989/09/25 10:42:12
Modified Date: 1989/09/25 06:36:03

Example3

While invoking this function if you pass the day and month values exceeding their range, they will be added to their parent values -

<?php
   //Creating a date
   $date = new DateTime();
   //Setting the date
   date_time_set($date, 24, 15, 36);   
   print("Date: ".date_format($date, "Y/m/d H:i:s"));
?>

Output

Since we have set the month value as 15, three months are added to the appropriate time -

Date: 2020/05/11 00:15:36

Example4

Try the following example -

$dateSrc = '2007-04-19 12:50 GMT';
$dateTime = date_create( $dateSrc);;
$retval = date_time_set( $dateTime, 20, 40, 10);
   
echo 'DateTime::format(): '.$dateTime->format('Y:M:D:H:i:s');
echo "\n";

# Using second function.
$dateTime = new DateTime($dateSrc);
$retval = $dateTime->setTime(20, 56,6);
   
echo 'DateTime::format(): '.$dateTime->format('Y:M:D:H:i:s');

Output

When the above code is executed, it will produce the following result -

DateTime::format(): 2007:Apr:Thu:20:40:10
DateTime::format(): 2007:Apr:Thu:20:56:06
