PHP代码执行计时脚本

Posted 2021-02-24

Place startTime() at beginning where timing is to start. Get the return value and set the start time variable. At end of script to time call execTime($start) passing the start time and this will calculate elapsed time of execution.

function startTime() {
    $mtime = microtime();
    $mtime = explode(' ', $mtime);
    $secs = $mtime[1] + $mtime[0];
    return $secs;
}
 
function execTime($start) {
    $end = startTime();
    $total = $end - $start;
    return '<Br>'.sprintf('Executed in %.6f seconds.', $total);
}
 
//Usage
 
$start = startTime();
 
//the code.....
 
echo execTime($start);
