directoryThe directory where the temporary filename will be created.

prefixThe prefix of the generated temporary filename.

Opmerking: > Only the first 63 characters of the prefix are used, the rest are ignored. Windows uses only the first three characters of the prefix.

Returns the new temporary filename (with path), or false on failure.

Voorbeeld: example

<?php
$tmpfname = tempnam("/tmp", "FOO");

$handle = fopen($tmpfname, "w");
fwrite($handle, "writing to tempfile");
fclose($handle);

// do something here

unlink($tmpfname);
?>
