$temp_file = tempnam(sys_get_temp_dir(), 'Tux');

-better to use the php methode 'getenv()' to access the enviroment vars
-the original 'sys_get_temp_dir()' don't use realpath, than it's better to make 'realpath(sys_get_temp_dir())'
<?php
if ( !function_exists('sys_get_temp_dir')) {
function sys_get_temp_dir() {
if( $temp=getenv('TMP') ) return $temp;
if( $temp=getenv('TEMP') ) return $temp;
if( $temp=getenv('TMPDIR') ) return $temp;
$temp=tempnam(__FILE__,'');
if (file_exists($temp)) {
unlink($temp);
return dirname($temp);
}
return null;
}
}
echo realpath(sys_get_temp_dir());
?>

There's no need to use a random name for the directory for tempnam.
Since a file and a directory can't share the same name on the filesystem, we can exploit this and simply use the name of the current file. It is guaranteed that the directory won't exist (because it's a file, of course).
Improving on the last post...
<?php
if ( !function_exists('sys_get_temp_dir')) {
function sys_get_temp_dir() {
if (!empty($_ENV['TMP'])) { return realpath($_ENV['TMP']); }
if (!empty($_ENV['TMPDIR'])) { return realpath( $_ENV['TMPDIR']); }
if (!empty($_ENV['TEMP'])) { return realpath( $_ENV['TEMP']); }
$tempfile=tempnam(__FILE__,'');
if (file_exists($tempfile)) {
unlink($tempfile);
return realpath(dirname($tempfile));
}
return null;
}
}
?>

I went ahead and slightly improved the function provided.
<?php
if ( !function_exists('sys_get_temp_dir')) {
function sys_get_temp_dir() {
if (!empty($_ENV['TMP'])) { return realpath($_ENV['TMP']); }
if (!empty($_ENV['TMPDIR'])) { return realpath( $_ENV['TMPDIR']); }
if (!empty($_ENV['TEMP'])) { return realpath( $_ENV['TEMP']); }
$tempfile=tempnam(uniqid(rand(),TRUE),'');
if (file_exists($tempfile)) {
unlink($tempfile);
return realpath(dirname($tempfile));
}
}
}
?>

better use
tempnam(":\n\\/?><","");
To detect path by creating a temporary file.
A random directoryname can exist (the chance is low, but it can be).
Better is to use signs, like :\n\\/?>< which are not valid, so realy NEVER a directory with this name can exist.

This function does not always add trailing slash. This behaviour is inconsistent across systems, so you have keep an eye on it.

To add support of sys_get_temp_dir for PHP4/5, use the following code:
<?php
if ( !function_exists('sys_get_temp_dir') )
{
// Based on http://www.phpit.net/
// article/creating-zip-tar-archives-dynamically-php/2/
function sys_get_temp_dir()
{
// Try to get from environment variable
if ( !empty($_ENV['TMP']) )
{
return realpath( $_ENV['TMP'] );
}
else if ( !empty($_ENV['TMPDIR']) )
{
return realpath( $_ENV['TMPDIR'] );
}
else if ( !empty($_ENV['TEMP']) )
{
return realpath( $_ENV['TEMP'] );
}
// Detect by creating a temporary file
else
{
// Try to use system's temporary directory
// as random name shouldn't exist
$temp_file = tempnam( md5(uniqid(rand(), TRUE)), '' );
if ( $temp_file )
{
$temp_dir = realpath( dirname($temp_file) );
unlink( $temp_file );
return $temp_dir;
}
else
{
return FALSE;
}
}
}
}
?>
