Edit report at https://bugs.php.net/bug.php?id=52074&edit=1 ID: 52074 Comment by: phpbugs at canavan dot de Reported by: php at richardneill dot org Summary: RFE: tempdir() countrpart to tempnam() Status: Open Type: Feature/Change Request Package: Directory function related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: An alternative would be to add a flag to tempnam(), e.g. tempnam ( string $dir , string $prefix, bool $create_a_directory ). Previous Comments: ------------------------------------------------------------------------ [2010-06-13 02:57:22] php at richardneill dot org Description: ------------ It would be really useful to have the ability to create a tempdir, with a unique name, which we know we can write to, and will be automatically cleaned up. 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
