[PHP] Benchmarking Class

[Chris]

 <?php
    class Benchmark{
        private $ElapsedTime = Array();
        
        function __destruct(){
            unset($ElapsedTime);
        }
        
        public function Mark($Handle){
            $this->ElapsedTime[$Handle] = (float) microtime(true);
        }
        
        public function Elapsed($Handle_Start, $Handle_Stop, $Decimals=false){
            $ElapsedTime = 0;
            
            if(isset($this->ElapsedTime[$Handle_Start]) && $this->ElapsedTime[$Handle_Start] > 0 && isset($this->ElapsedTime[$Handle_Stop]) && $this->ElapsedTime[$Handle_Stop] > 0){
                if($Decimals !== false){
                    $ElapsedTime = round(($this->ElapsedTime[$Handle_Stop] - $this->ElapsedTime[$Handle_Start]), $Decimals);
                }else{
                    $ElapsedTime = abs($this->ElapsedTime[$Handle_Stop] - $this->ElapsedTime[$Handle_Start]);
                }
            }
            
            return $ElapsedTime;
        }
    }
?>  

Due to the fact many people may not understand it, it is rather simple here is an example;

 <?php
    $Benchmark = new Benchmark();
    
    $Benchmark->Mark('start');
        usleep(1000000);
    $Benchmark->Mark('stop');
    
    echo $Benchmark->Elapsed('start', 'stop');
?>
