drupal_tempnam

7 file.inc drupal_tempnam($directory, $prefix)

Creates a file with a unique filename in the specified directory.

PHP's tempnam() does not return a URI like we want. This function will return a URI if given a URI, or it will return a filepath if given a filepath.

Compatibility: normal paths and stream wrappers.

Parameters

$directory: The directory where the temporary filename will be created.

$prefix: The prefix of the generated temporary filename. Note: Windows uses only the first three characters of prefix.

Return value

The new temporary filename, or FALSE on failure.
