Using pear::benchmarking timer to implement the PHP program timing

Create an Object
$timer = new Benchmark_timer ();

Start the timer.
$timer->start ();

A piece of script for testing
For ($i =0 $i <1000; $i + +)
{
We don't have any here
}

Set markup
$timer->setmarker ("Mark1");

To output between two points
echo $timer->timeelapsed ("Start", "Mark1");
?>
Then, you can get 0.000543 of these results, roughly the time between the start and the Mark1 point.
Class method
Method: Benchmark_timer ([Mixed $auto = false])
Description: Constructor, start timer record.
Parameters: Boolean $auto, the default is False, and if set to True, the timer results are automatically printed. form the table below
Time index ex time%
Start 1099020859.80505200-0.00%
Stop 1099020859.80595000 0.000898 100%
total-0.000898 100%

Lists the start/End time index, the elapsed time between the previous tag and the previous one, the total elapsed time (so the stop point is 100%), and the total duration.
Method: Display ()
Description: Prints the information returned by the GetOutput method.
form the following table:
Time index ex time%
Start 1099021292.32145600-0.00%
Mark1 1099021292.32202000 0.000564 46.38%
MARK2 1099021292.32209700 0.000077 6.33%
Stop 1099021292.32267200 0.000575 47.29%

Method: Getprofiling ()
Description: Returns the timer information. will be shaped like
