note 114488 added to function.exec

Side-note: regarding the API comment "For practical reasons, it is currently not allowed to have .. components in the path to the executable." It is still possible to pass the shell as the first command and a relative path to the script as the second, so this limitation/security mechanism is not much of one. "sh" can be used to run non-scripts with relative paths via something like this: $out = null; $rc= 0; exec('sh -c "exec /bin/../bin/ls"', $out, $rc); print_r( $out); echo 'rc = '.$rc."\n"; effectively bypassing any "security" gained by the ".." limitation. ---- Server IP: 87.106.1.137 Probable Submitter: 88.217.154.36 ---- Manual Page -- http://php.net/manual/en/function.exec.php Edit -- https://master.php.net/note/edit/114488 Del: integrated -- https://master.php.net/note/delete/114488/integrated Del: useless -- https://master.php.net/note/delete/114488/useless Del: bad code -- https://master.php.net/note/delete/114488/bad+code Del: spam -- https://master.php.net/note/delete/114488/spam Del: non-english -- https://master.php.net/note/delete/114488/non-english Del: in docs -- https://master.php.net/note/delete/114488/in+docs Del: other reasons-- https://master.php.net/note/delete/114488 Reject -- https://master.php.net/note/reject/114488 Search -- https://master.php.net/manage/user-notes.php
