Dear Experts,

How can we calculate, the running/execution time of a php file?

I mean lets say I have 2 files, file1.php and file2.php doing the same function but in different logic, so how can i say that the file1.php is faster or file2.php is faster.

By loading them in browsers, It alot depends on present internet connection speed so we cannot rely on that. What are the other possible ways of checking this.

Regards,
Tripat

At the start of the file:


function getmicrotime(){
    list($usec, $sec) = explode(" ",microtime());
    return ((float)$usec + (float)$sec);
    }

$time_start = getmicrotime();

.....

and at the end of the file

echo "execution time : ".getmicrotime() - $time_start;

I'm not used to asp, but I found a snippet at

http://www.4guysfromrolla.com/webtech/122799-1.shtml


Dim Iterations, StartTime, ElapsedTime, AverageTimePerIteration, X

Iterations = 1000
StartTime = Timer

For X = 1 TO Iterations
   '... do operations to be timed
Next

ElapsedTime = Timer - StartTime
AverageTimePerIteration = ElapsedTime / Iterations
