What does *not* work correctly is what PHP does when a file or directory does not exist. if (path_exists_and_is_inside_open_basedir($path)) { // (A) good: exists } else { if (open_basedir_is_enabled()) { // (B) bad: "open_basedir restriction in effect" // what if $path does not exist and is *inside* open_basedir! } else { // (C) good: does not exist } } Previous Comments: ------------------------------------------------------------------------ [2021-05-18 18:08:29] bugs-php dot a2 at x25 dot pl And how does it make not open_basedir problem? You are saying that I can't check if file/dir exists because it might not exist. Then how about mkdir()? or file_exists() or is_file()? mkdir() cant create directory because it also does not exist? cat a.php <? ini_set("open_basedir","/home/naox/public_html/test"); mkdir("/home/naox/public_html/test"); php a.php Warning: mkdir(): open_basedir restriction in effect. File(/home/naox/public_html/test) is not within the allowed path(s): (/home/naox/public_html/test) in /home/naox/public_html/naox.vipserv.org/a.php on line 3 ------------------------------------------------------------------------ [2021-05-15 18:57:57] requinix@php.net Duplicate of bug #52065 The issue is not open_basedir but that the functionality supporting is_dir() reports that the path does not exist, and the reason for that is assumed to be an open_basedir restriction. If public_html/test existed then you would not get this warning. ------------------------------------------------------------------------ [2021-05-15 09:03:23] bugs-php dot a2 at x25 dot pl No, it does not exist but it should not matter. ------------------------------------------------------------------------ [2021-05-15 01:52:20] requinix@php.net Does public_html/test exist? ------------------------------------------------------------------------ [2021-05-14 23:35:43] bugs-php dot a2 at x25 dot pl Description: ------------ open_basedir does not work as it should: Test script: --------------- <? ini_set("open_basedir","/home/naox/public_html/test"); is_dir("/home/naox/public_html/test"); Actual result: -------------- Warning: is_dir(): open_basedir restriction in effect.
