Creating a temporary file with .pdf extension php tempnam

Question

Is it possible to create a .pdf file extension when using tempname? I need to send an e-mail with a file created using tempname. (I can send the file, but I need the .pdf extension)

Answer 1

$tempname = tempnam('', 'report_');
rename($tempname, $tempname .= '.pdf');

// now use the new filename as you wish
var_dump($tempname, is_file($tempname));

By default such files are created with the strictest level of privileges possible. Typically they're only readable by the current user. It may be necessary to make these files group-readable:

chmod($original, 0640);

Or even world-readable, although this is inadvisable:

chmod($original, 0644);
