Hi All I'm trying to calculate elapsed time in php. REQUEST_TIME_FLOAT The timestamp of the start of the request, with microsecond precision. After that, we will get the difference between these two clock times which will be the time take to execute the script. I have a song track that has the song length in milliseconds. hadl / microtime_diff.php. Return Values. While doing some experiments on using microtime()'s output for an entropy generator I found that its microsecond value was always quantified to the nearest hundreds (i.e. All gists Back to GitHub Sign in Sign up Sign in Sign up Instantly share code, notes, and snippets. - This function checks the keys of the arrays, array_diff only compares the values.
