note 110679 added to function.tmpfile

Beware that PHP's tmpfile is not an equivalent of unix' tmpfile. PHP (at least v. 5.3.17/linux I'm using now) creates a file in /tmp with prefix "php", and deletes that file on fclose or script termination. So, if you want to be sure that you don't leave garbage even in case of a fatal error, or killed process, you shouldn't rely on this function. Use the classical method of deleting the file after creation: <?php $fn = tempnam ('/tmp', 'some-prefix-'); if ($fn) { $f = fopen ($fn, 'w+'); unlink ($fn); // even if fopen failed, because tempnam created the file if ($f) { do_something_with_file_handle ($f); } } ?> ---- Server IP: 95.130.168.26 Probable Submitter: 94.53.199.174 ---- Manual Page -- http://www.php.net/manual/en/function.tmpfile.php Edit -- https://master.php.net/note/edit/110679 Del: integrated -- https://master.php.net/note/delete/110679/integrated Del: useless -- https://master.php.net/note/delete/110679/useless Del: bad code -- https://master.php.net/note/delete/110679/bad+code Del: spam -- https://master.php.net/note/delete/110679/spam Del: non-english -- https://master.php.net/note/delete/110679/non-english Del: in docs -- https://master.php.net/note/delete/110679/in+docs Del: other reasons-- https://master.php.net/note/delete/110679 Reject -- https://master.php.net/note/reject/110679 Search -- https://master.php.net/manage/user-notes.php
