Hi internals, As a follow-up on my previous message here (https://marc.info/?l=php-internals&m=168912164828942&w=2), I would like to start the discussion on the "Support optional suffix parameter in tempnam" RFC. https://wiki.php.net/rfc/tempnam-suffix-v2

Hello, The RFC does not explain what benefits brings using tempnam($directory, $prefix, $suffix) over using tempnam($directory, $prefix).$suffix , which you can already use? Côme

Hi Côme, Thanks for the input and for going through the proposal. As the tempnam short description (https://www.php.net/manual/en/function.tempnam.php) states tempnam — __Create__ file with unique file name So tempnam 1) creates a file with specific permissions in a given path ($directory); and 2) returns the full path of the created file on success. For the sole purpose of obtaining a file path (2), I see no reasons for not using "tempnam($directory, $prefix).$suffix" as you suggested. However, to create the temporary file (1) allowing appending a suffix string to the created file, we would need to change tempnam. This is the purpose of this RFC. In other words, although the return value of "tempnam($directory, $prefix).$suffix" and the proposed "tempnam($directory, $prefix, $suffix)" __may__ be the same, the outcome of running each of those, is not. The second paragraph of the RFC introduction says "It would be useful to allow users to also specify a suffix when __generating__ temporary files. [...]" Do you have any suggestions on how we could improve the RFC introduction text to make this clearer to readers of this RFC? -- Athos Ribeiro
