Previous Comments: ------------------------------------------------------------------------ [2016-07-21 23:38:53] anrdaemon at freemail dot ru Description: ------------ realpath(), according to the documentation, is supposed to unwind every symlink and relative reference in the given string and produce an absolute and unambiguous path. Well… it doesn't perform its job quite as desired. Affected PHP versions: same behavior observed in 5.3.29, 5.6.23, 7.0.8 and 7.1.0b1. Test script: --------------- <?php $rootdir = substr($_SERVER['SystemRoot'], 0, 3); $tmpdir = getenv('TEMP'); shell_exec("mklink /J \"{$rootdir}home\" \"{$rootdir}Users\""); shell_exec("mklink /J \"{$tmpdir}\\test.dir\" \"{$rootdir}home\\Public\\Desktop\""); $file = "{$tmpdir}\\test.dir\\desktop.ini"; $rfile = realpath($file); printf("orig.file name: %s\n", $file); printf("realpath(name): %s\n", $rfile); printf("THE real name: %s\n", realpath($rfile)); if($rfile != realpath($rfile)) print "Fail as is.\n"; rmdir("{$rootdir}home"); rmdir("{$tmpdir}\\test.dir"); Expected result: ---------------- orig.file name: C:\Users\ANRDAE~1\AppData\Local\Temp\test.dir\desktop.ini realpath(name): C:\Users\Public\Desktop\desktop.ini THE real name: C:\Users\Public\Desktop\desktop.ini Actual result: -------------- orig.file name: C:\Users\ANRDAE~1\AppData\Local\Temp\test.dir\desktop.ini realpath(name): C:\home\Public\Desktop\desktop.ini THE real name: C:\Users\Public\Desktop\desktop.ini Fail as is. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72642&edit=1
