How to Retrieve the Current Time in Milliseconds in PHP?

Retrieving the Current Time in Milliseconds with PHP

In PHP, the time() function returns the current time in seconds. However, for scenarios where greater precision is required, it may be necessary to obtain the current time in milliseconds.

Solution:

The solution involves utilizing microtime(true). This function returns the current time measured in seconds and microseconds, with microseconds representing the fractional part. To convert this value to milliseconds:

<code class="php">$microseconds = microtime(true);
$timestamp = floor($microseconds * 1000); // Convert to milliseconds</code>

Example:

<code class="php">$timestamp = floor(microtime(true) * 1000);

echo 'Timestamp in milliseconds: ' . $timestamp . '<br>';</code>

Output:

Timestamp in milliseconds: 1631685547387

By utilizing this approach, you can retrieve the current time in milliseconds with greater accuracy compared to using time().
