PHP Optimization Techniques

[Callister]

Greetings everyone,

 

I'm in the process of optimizing code that is significantly old that was programmed in my lesser years.  I have learned a lot about better ways of doing things, however I have a question.

 

What is the best way to benchmark optimization progress? Is there a variable or any way I can configure to see if a script is in actuality more efficient [rather than just looking nicer]?

 

Thanks guys!

<?php
$t1 = microtime(true);
  // method A
$t2 = microtime(true);
  // method B
$t3 = microtime(true);

printf ('Method A - %0.5f secs<br>', $t2-$t1);
printf ('Method B - %0.5f secs<br>', $t3-$t2);
?>

<?php
$t1 = microtime(true);
  // method A
$t2 = microtime(true);
  // method B
$t3 = microtime(true);

printf ('Method A - %0.5f secs<br>', $t2-$t1);
printf ('Method B - %0.5f secs<br>', $t3-$t2);
?>

 

Or, use the Timer class from PEAR.  Works quite well.
