Start and stop a timer PHP

Question

I need some information regarding starting and stopping a timer in PHP. I need to measure the elapsed time from the start of my .exe program (I\'m using exec()

Answer 1

You can use Timer Class

    start();
   }

   # Start counting time
   function start() {
      $this->start = $this->_gettime();
   }

   # Stop counting time
   function stop() {
      $this->stop    = $this->_gettime();
      $this->elapsed = $this->_compute();
   }

   # Get Elapsed Time
   function elapsed() {
      if ( !$elapsed )
         $this->stop();

      return $this->elapsed;
   }

   # Resets Timer so it can be used again
   function reset() {
      $this->start   = 0;
      $this->stop    = 0;
      $this->elapsed = 0;
   }

   #### PRIVATE METHODS ####

   # Get Current Time
   function _gettime() {
      $mtime = microtime();
      $mtime = explode( " ", $mtime );
      return $mtime[1] + $mtime[0];
   }

   # Compute elapsed time
   function _compute() {
      return $this->stop - $this->start;
   }
}
