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

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;
}
}
?>

This function does not account for virtualhost-specific modifications to the temp path and/or open_basedir:
<Virtualhost>
php_admin_value open_basedir /home/user
php_admin_value upload_tmp_dir /home/user/tmp
php_admin_value session.save_path /home/user/tmp
</Virtualhost>
Within this config it still returns /tmp

-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());
?>

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));
}
}
}
?>
