tempnam

Description

Creates a file with a unique filename in the specified directory. If the directory does not exist, tempnam() may generate a file in the system's temporary directory, and return the name of that.

Prior to PHP 4.0.6, the behaviour of the tempnam() function was system dependent. On Windows the TMP environment variable will override the dir parameter, on Linux the TMPDIR environment variable has precedence, while SVR4 will always use your dir parameter if the directory it points to exists. Consult your system documentation on the tempnam(3) function if in doubt.

Returns the new temporary filename, or the FALSE string on failure.

Example 1. tempnam() example <?php $tmpfname = tempnam ("/tmp", "FOO"); $handle = fopen($tmpfname, "w"); fwrite($handle, "writing to tempfile"); fclose($handle); // do here something unlink($tmpfname); ?>
