(PHP 3 >= 3.0.13, PHP 4, PHP 5)

tmpfile -- Creates a temporary file

## Description

resource tmpfile ( void )

Creates a temporary file with a unique name in read-write (w+) mode, returning a file handle similar to the one returned by fopen(). The file is automatically removed when closed (using fclose()), or when the script ends.

For details, consult your system documentation on the tmpfile(3) function, as well as the `stdio.h` header file.

範例 1. tmpfile() example

`<?php $temp = tmpfile(); fwrite($temp, "writing to tempfile"); fseek($temp, 0); echo fread($temp, 1024); fclose($temp); // this removes the file ?>`

The above example will output:

    writing to tempfile
