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?

从 fopen("php://temp") 入口点开始，将其行为与 tempnam() 进行比较，尤其要关注 /tmp/php* 下的文件是如何创建和删除的。定义所需的前缀语义，并验证生成的名称能够改善调试，同时保持自动删除不变。
