note 130686 added to function.is-writable

I've encountered an unexpected issue: even though the directory allows writing files, it keeps returning false. ``` $a = 'C:/Users/*/OneDrive/work/www/'; $b = "{$a}admin/"; var_dump($a); var_dump(is_writable($a)); var_dump($b); var_dump(is_dir($b)); var_dump(is_writable($b)); var_dump(file_put_contents($b.'test.txt','hello')); ``` - string 'C:/Users/*/OneDrive/work/www/' (length=33) - boolean true - string 'C:/Users/*/OneDrive/work/www/admin/' (length=39) - boolean true - boolean false - int 5 ---- Server IP: 206.189.2.9 Probable Submitter: 222.213.202.49 ---- Manual Page -- https://php.net/manual/en/function.is-writable.php Edit -- https://main.php.net/note/edit/130686 Del: integrated -- https://main.php.net/note/delete/130686/integrated Del: useless -- https://main.php.net/note/delete/130686/useless Del: bad code -- https://main.php.net/note/delete/130686/bad+code Del: spam -- https://main.php.net/note/delete/130686/spam Del: non-english -- https://main.php.net/note/delete/130686/non-english Del: in docs -- https://main.php.net/note/delete/130686/in+docs Del: other reasons-- https://main.php.net/note/delete/130686 Reject -- https://main.php.net/note/reject/130686 Search -- https://main.php.net/manage/user-notes.php
