How to Convert Datetime into Milliseconds in PHP

Converting DateTime into milliseconds in PHP can be useful for various applications, such as timestamping events or measuring time intervals with precision. In this guide, I'll walk you through the straightforward process of converting DateTime objects into milliseconds in PHP, step by step.

So, let's see how to convert DateTime into milliseconds in PHP, how to get current time in milliseconds in php, php micro time, php milliseconds, and convert time to milliseconds laravel 8/9/10.

Here's a simple example demonstrating how to convert a DateTime object into milliseconds in PHP:

<?php
  
/* Your date string */
$dateString = "2024-03-01 12:00:00";
  
/* Create a DateTime object */
$dateTime = new DateTime($dateString);
  
/* Get the timestamp in seconds */
$timestampInSeconds = $dateTime->getTimestamp();
  
/* Convert seconds to milliseconds */
$timestampInMilliseconds = $timestampInSeconds * 1000;
  
/* Output the result */
echo "Milliseconds: " . $timestampInMilliseconds;
  
?>

 

Here's an example illustrating the conversion of a DateTime string into milliseconds using strtotime() in PHP:

// DateTime string representing the date and time
$dateString = '2024-03-01 12:00:00';

// Convert DateTime string to a Unix timestamp using strtotime()
$timestamp = strtotime($dateString);

// Convert timestamp to milliseconds
$milliseconds = $timestamp * 1000;

// Display the milliseconds
echo "Milliseconds: $milliseconds";

// Utilize the milliseconds as needed

 

Here's a simple example demonstrating how to convert a DateTime object into milliseconds in PHP:

// Create a DateTime object
$date = new DateTime('2024-03-01 12:00:00');

// Convert DateTime to a timestamp
$timestamp = $date->format('U');

// Convert timestamp to milliseconds
$milliseconds = $timestamp * 1000;

// Display the milliseconds
echo "Milliseconds: $milliseconds";

// Utilize the milliseconds as needed

Converting DateTime into milliseconds in PHP is a straightforward process that involves converting the DateTime object to a timestamp and then multiplying it by 1000 to obtain the milliseconds.
