note 105832 added to function.realpath

@netmosfera, there may be something wrong with your benchmark - possibly you read the directory names from the filesystem as part of the benchmark and one read from the disk while the other read from the buffer. For the following code using <?php // $path[] = a recursive list of files from '.', 84 names. $t0 = microtime(true); foreach ($a as $k => $path) $a[$k] = $path; $t1 = microtime(true); foreach ($a as $k => $path) $a[$k] = realpath($path); $t2 = microtime(true); ?> I averaged about 0.033 ms for the first loop and 0.440 ms for the second, 500 times faster than your test.
