How to find PHPs tmp folder relative to script running?

Question

Hello all,

Is it possible to find PHP tmp folder at run time?

I am uploading files and I am making use of:

$_FILES['upfile']['tmp_name']

However, one of the APIs I am making use of requires that I have to give the full file path of the uploaded file relative to my script! A bit annoying but it has to be done.

Any ideas on how I can do this?

EDIT

Currently. I am doing this, as I know how many levels to go up but I am sure the tmp folder can be at different locations for different servers.

$file = '../..'.$_FILES['upfile']['tmp_name'];

Thanks all

Answer 1

Really, if possible, I'd recommend you move the uploaded file into its permanent location before you start interacting with other APIs regarding it. You're going to have to anyway, and then you know its relative location easily.

If you can't do that, I suppose you can work out the relative path by analyzing dirname($_FILES['upfile']['tmp_name']) and dirname(__FILE__).

getcwd() should output the current working directory.

<?php

            // Create a temporary file in the temporary 
            // files directory using sys_get_temp_dir()

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

    echo $temp_file;



    // on my machine this echoes something like "/tmp/filename7gkPjR"
?>

Not sure if this is a foolproof way but it works on my server. In addition, there is probably a way to replace folder names with .. but that is beyond me.

$folders = explode('/', $_SERVER['SCRIPT_FILENAME']);
for ($i = 2; $i < count($folders); $i++) $dir .= '../';
$dir = substr($dir,0,-1);
$dir = $dir.$_FILES['upfile']['tmp_name'];
