How can the precision of time measurement in PHP be adjusted for different requirements?

To adjust the precision of time measurement in PHP for different requirements, you can use the microtime() function which returns the current Unix timestamp with microseconds. By multiplying the result of microtime() by 1000, you can get the time in milliseconds or adjust the precision as needed.

// Adjusting time measurement precision in PHP
$microtime = microtime(true) * 1000; // Get the current time in milliseconds
echo $microtime; // Output the time with adjusted precision
