tempnam

(PHP 4, PHP 5, PHP 7)

tempnam — Create file with unique file name

Descrierea

tempnam ( string $dir , string $prefix ) : string

Creates a file with a unique filename, with access permission set to 0600, in the specified directory. If the directory does not exist or is not writable, tempnam() may generate a file in the system's temporary directory, and return the full path to that file, including its name.

Parametri

dir

The directory where the temporary filename will be created.

prefix

The prefix of the generated temporary filename.

Notă: Windows uses only the first three characters of prefix.

Valorile întoarse

Returns the new temporary filename (with path), or FALSE on failure.

Exemple

Example #1 tempnam() example

<?php
$tmpfname = tempnam("/tmp", "FOO");

$handle = fopen($tmpfname, "w");
fwrite($handle, "writing to tempfile");
fclose($handle);

// do here something

unlink($tmpfname);
?>

Note

Notă: If PHP cannot create a file in the specified dir parameter, it falls back on the system default. On NTFS this also happens if the specified dir contains more than 65534 files.
