FileSystem::tempnam

public FileSystem::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

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

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

Return value

string|bool The new temporary filename, or FALSE on failure.

Overrides FileSystemInterface::tempnam
