How can a string be converted into microtime in PHP?

To convert a string into microtime in PHP, you can use the strtotime() function to convert the string into a Unix timestamp and then use the microtime() function to get the current microtime. By combining these two values, you can create a microtime representation of the string.

$string = "2022-01-01 12:00:00";
$timestamp = strtotime($string);
$microtime = microtime(true);
$result = $timestamp + $microtime;

echo "Microtime representation of the string: " . $result;
