Performance tests: Default arguments

at 2006-08-15 in Experiments by friebe (0 comments)

Assume we have the following function:

<?php 
  function fixture($r1, $r2, $o1= array(1, 2), $o2= NULL, $o3= 'foo') {
    // ...
  }
?>

What's faster? Calling it via fixture(1, 2) or supplying all the default arguments (fixture(1, 2, array(1, 2), NULL, 'foo');). The answer is: It's equivalent.

See this experiment for details.
