Timestamping with Milliseconds in PHP

In the world of programming, tracking time intervals with precision is often essential. PHP provides the time() function to retrieve the current timestamp in seconds. However, for scenarios requiring finer granularity, you may wonder if there's a way to get the time in milliseconds.

The Solution: Harnessing Microtime

PHP offers the microtime() function to retrieve a much more precise timestamp that includes microseconds. To obtain the time in milliseconds, use the following formula:

<code class="php">$milliseconds = floor(microtime(true) * 1000);</code>
Copy after login

This formula multiplies the microtime value with 1000 to convert it from microseconds to milliseconds and then rounds it down to an integer using the floor() function, providing you with the current time in milliseconds.
