note 97086 added to function.tempnam

tempnam() function does not support custom stream wrappers registered by stream_register_wrapper(). For example if you'll try to use tempnam() on Windows platform, PHP will try to generate unique filename in %TMP% folder (usually: C:\WINDOWS\Temp) without any warning or notice. <?php // << ...custom stream wrapper goes somewhere here...>> echo '<pre>'; error_reporting(E_ALL); ini_set('display_errors', true); clearstatcache(); stream_register_wrapper('test', 'MemoryStream'); mkdir('test://aaa'); mkdir('test://aaa/cc'); mkdir('test://aaa/dd'); echo 'PHP '.PHP_VERSION; echo '<br />node exists: '.file_exists('test://aaa/cc'); echo '<br />node is writable: '.is_writable('test://aaa/cc'); echo '<br />node is dir: '.is_dir('test://aaa/cc'); echo '<br />tempnam in dir: '.tempnam('test://aaa/cc', 'tmp'); echo "<br /></pre>"; ?> ouputs: -------------------- PHP 5.2.13 node exists: 1 node is writable: 1 node is dir: 1 tempnam in dir: C:\Windows\Temp\tmp1D03.tmp If you want to create temporary file, you have to create your own function (which will probably use opendir() and fopen($filename, "x") functions) ---- Server IP: 194.24.174.37 Probable Submitter: 82.210.157.150 ---- Manual Page -- http://www.php.net/manual/en/function.tempnam.php Edit -- https://master.php.net/note/edit/97086 Del: integrated -- https://master.php.net/note/delete/97086/integrated Del: useless -- https://master.php.net/note/delete/97086/useless Del: bad code -- https://master.php.net/note/delete/97086/bad+code Del: spam -- https://master.php.net/note/delete/97086/spam Del: non-english -- https://master.php.net/note/delete/97086/non-english Del: in docs -- https://master.php.net/note/delete/97086/in+docs Del: other reasons-- https://master.php.net/note/delete/97086 Reject -- https://master.php.net/note/reject/97086 Search -- https://master.php.net/manage/user-notes.php
