tmpfile

(PHP 4, PHP 5, PHP 7)

tmpfileCreates a temporary file

Description

tmpfile ( void ) : resource

Creates a temporary file with a unique name in read-write (w+) mode and returns a file handle.

The file is automatically removed when closed (for example, by calling fclose(), or when there are no remaining references to the file handle returned by tmpfile()), or when the script ends.

Caution

If the script terminates unexpectedly, the temporary file may not be deleted.

Return Values

Returns a file handle, similar to the one returned by fopen(), for the new file or FALSE on failure.

Examples

Example #1 tmpfile() example

<?php
$temp 
tmpfile();
fwrite($temp"writing to tempfile");
fseek($temp0);
echo 
fread($temp1024);
fclose($temp); // this removes the file
?>

The above example will output:

writing to tempfile
