drupal_tempnam
function drupal_tempnam
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.

'://' . drupal_basename($filename); } else { return FALSE; } } else { // Handle as a normal tempnam() call. return tempnam($directory, $prefix); } }
