Improvement of php://temp to add automatically prefix for debugging

Description

Hi,

Any php code that uses temporary files uses fopen("php://temp", "w") a lot. This function does not allow putting prefix or suffix like tempnam() . And because the first expression also deletes the file automatically at file closure, it is much more convenient.

So in the end, with a big application and lots of dependencies, there are many many temporary files in /tmp/php*. When debugging the source of these files, for example to know why there are big files, it is very difficult, and requires reading source code of the app and its dependencies, and then changing to tempnam() with a prefix, which also requires manual deleting.

Instead, is-it possible to automatically add as prefix the php file name? Example:
S3Upload.php => the fopen would generate in Linux something like /tmp/php-S3Upload.php-DOoeG

I don't think there are any negative impact, I guess?

Inizia dal punto di ingresso fopen("php://temp") e confronta il suo comportamento con tempnam(), in particolare il modo in cui vengono creati e rimossi i file in /tmp/php*. Definisci la semantica del prefisso desiderata e verifica che i nomi generati migliorino il debugging, mantenendo al contempo intatta l'eliminazione automatica.
