How would that be possible in the general case? Even tempnam(3) is not without race-condition; a function that would return the name of a temporary directory, is as well. Given that this rather doubtful request had not much traction for more than ten years, I'm closing as WONTFIX. Feel free to pursue the RFC process[1], if you want to see this feature implemented.

For example, if I want to run an external command (with exec() ) which will write to a file, where: - it must be known that file-creation can succeed - the file does not exist at the moment Test script: --------------- Some applications will refuse to overwrite an existing file (that we created with tempnam()), because they don't want to clobber it. What we effectively need is a race-free way to assign a temp-filename without actually creating the file. Using tmpfile() doesn't help, because we can't pass a file-handle to php's exec(). ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=52074&edit=1
