PHP: tmpfile - Manual

tmpfile

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

tmpfile -- Creates a temporary file

Description

resource tmpfile ( void )

Creates a temporary file with an 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.

Example 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

See also tempnam().

tmpfile() does not return the name of the file it created.  



To get access to the file, use something like this:



$tempfn = tempnam("","");

$temp = fopen($tempfn, "w");

fwrite($temp, $data);

fclose($temp);



//your functions here, ie:

$size=getimagesize($tempfn);



unlink($tempfn);
