par défaut, microtime() retourne une chaîne de caractères au format "msec sec", où sec est le nombre de secondes depuis l'époque unix ( , :: gmt), et msec est le nombre de microsecondes qui se sont écoulées depuis sec, exprimé en secondes. si get_as_float est défini à true , alors microtime()

return value: returns the string "microsec sec" by default, where sec is the number of seconds since the unix epoch (:: january , gmt), and microsec is the microseconds part. if the get_as_float parameter is set to true, it returns a float representing the current time in seconds since the unix epoch accurate to  the short answer is: $milliseconds = round(microtime(true) );.

put this at the end of your php file: display script end time $time_end = microtime(true); dividing with will give the execution time in minutes other wise seconds $execution_time = ($time_end $time_start)/; execution time of the script echo 'total execution time: '.$execution_time.' mins';. the php microtime function grabs the unix timestamp (currently about hex ebc or decimal ,,,) from one system call, and the microsecond time from another system call. it then makes them into a character string. then, if you call it with (true) it converts that number to a bit ieee

you can do the entire thing in one line using regex: $value = preg_replace('/()\.(\d) (\d)/', '$$$', microtime());. example: <?php $microtime = microtime(); var_dump( $microtime ); var_dump( preg_replace('/()\.(\d) (\d)/', '$$$', $microtime) ); ?> output: string() ". "  calculations (with the parameter get_as_float as true) will give you results in seconds, according to php documentation. by default, microtime() returns a string in the form "msec sec", where sec is the number of seconds since the unix epoch (:: january , gmt), and msec measures microseconds that have

a solution without using a dateformatter doing it all by yourself: $minutes = floor($time ); $seconds = $time ; $minutes = str_pad($minutes, , '', str_pad_left); $seconds = str_pad($seconds, , '', str_pad_left); echo "process time: $minutes:$seconds";. note: this also works if minutes  it seems that this microtime() is showing up weird because php has a threshold, on either side of which it displays either a number in scientific notation or one in decimal notation. both of these are technically "floats" (see documentation). it seems that this threshold is somewhere between . seconds and
