Edit report at https://bugs.php.net/bug.php?id=64927&edit=1 ID: 64927 Updated by: cmb@php.net Reported by: myustc at 163 dot com Summary: realpath() still returns current path on Null/false argument -Status: Open +Status: Verified Type: Documentation Problem Package: Filesystem function related Operating System: Mac OS X 10.6.8 PHP Version: 5.3.25 Block user comment: N Private report: N New Comment: The PHP 5.0.0 changelog entry has been removed in the meantime. However, the behavioral change in PHP 5.2.1 pointed out by Sjon is not yet documented. Previous Comments: ------------------------------------------------------------------------ [2013-05-29 18:47:20] Sjon at hortensius dot net It seems that Changelog notice is incorrect; see http://3v4l.org/MJUQe The only difference is that since 5.2 the cwd is returned ------------------------------------------------------------------------ [2013-05-28 07:12:05] myustc at 163 dot com Sorry, I meant the Changelog part: ------------------- 5.0.0 Prior to this release, a blank or NULL path would cause realpath() to return the directory name of the script. ------------------- which sounds to me as if such behavior was removed since 5.0.0. Correct me if I'm wrong... ------------------------------------------------------------------------ [2013-05-27 07:48:06] earlchaos at gmail dot com I don't see the problem here? From the manual: path The path being checked. Note: Whilst a path must be supplied, the value can be blank or NULL In these cases, the value is interpreted as the current directory. ------------------------------------------------------------------------ [2013-05-27 07:42:13] myustc at 163 dot com Description: ------------ --- From manual page: http://www.php.net/function.realpath#refsect1-function.realpath-changelog --- I'm using PHP 5.3.15 (cli) (built: Jul 31 2012 18:42:11). When I'm tracking a bug in Yii, I realized that it's the issue of php function realpath(). the reproducing is very easy, just run this in console: php -r "var_dump(realpath(false), realpath(null), realpath(''));" Test script: --------------- <?php var_dump(realpath(false)); var_dump(realpath(null)); var_dump(realpath('')); Expected result: ---------------- I should see output as below: bool(false) bool(false) bool(false) Actual result: -------------- output:(the actual path depends) string(22) "/Users/yaowenh/phpunit" string(22) "/Users/yaowenh/phpunit" string(22) "/Users/yaowenh/phpunit" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64927&edit=1
