+Therefore, there is no performance regression to normal function calls (defined functions). The margin of error for this test was on the order of +-0.00004 seconds.
+=== Constants ===
+constants were generated and placed in a single file. The following test script was used to test if there was any change to function call time for a defined function:
+<file php benchmark_constants.php>
+<?php
+require_once 'constants.php';
+$start = microtime(true);
+for ($i = 0; $i < 1000; $i++) {
+        $name = 'test' . $i;
+        constant($name);
+}
+$end = microtime(true);
+echo "Completed in " . ($end - $start) . " seconds\n";
+?>
+</file>
+  * Master: average 0.000228 Seconds to call 1000 constants
+  * Proposal: average 0.000221 Seconds to call 1000 constants
+Therefore, there is no performance regression to normal constant lookups (defined constants).
