[development] coding standard question

[mark burdett]

Hi, in some simple command-line tests I could not find a difference (in php 5.2)

  true: 1.32612895966  TRUE: 1.38275790215
  true: 1.34794092178  TRUE: 1.39009809494
  true: 1.34102320671  TRUE: 1.38674616814
  true: 1.2856991291  TRUE: 1.27452993393
  true: 1.34056401253  TRUE: 1.2749080658
  true: 1.31166195869  TRUE: 1.33323001862
  true: 1.34053897858  TRUE: 1.27428483963
  true: 1.28342199326  TRUE: 1.33444595337

<?php
$loop = 0;
while ($loop < 8) {
  $count = 0;
  $start = microtime(true);
  while ($count < 4000000) {
    $test = true;
    if (true) {
      $count++;
    }
  }
  echo '  true: ';
  echo microtime(true) - $start;

  $count = 0;
  $start = microtime(true);
  while ($count < 4000000) {
    $test = TRUE;
    if (TRUE) {
      $count++;
    }
  }
  echo '  TRUE: ';
  echo microtime(true) - $start;
  echo "\n";
  $loop++;
}
