revTalk - iRev - revWeb - PHP - iPhone and back again

[Thomas McGrath III]

I was away for a few days. Back now. Here is the PHP script I used:

<?php
$uploaddir = './';      //Uploading to same directory as PHP file
$file = basename($_FILES['userfile']['name']);
$uploadFile = $file;
$randomNumber = rand(0, 99999);
$newName = $uploadDir . "Demoted" . $randomNumber . $uploadFile;


if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
	echo "Temp file uploaded. \r\n";
} else {
	echo "Temp file not uploaded. \r\n";
}

if ($_FILES['userfile']['size']> 500000) {
	exit("Your file is too large. It must be lest than 500k");
}

// This is an if statement that logs in the xCode debugger console the  
server variables and
// the directory and format of file and size of file and type of file
// ECHO sends back to the iphone the important information which can  
be trapped there for its own use
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) {
     $postsize = ini_get('post_max_size');   //Not necessary, I was  
using these
     $canupload = ini_get('file_uploads');    //server variables to  
see what was
     $tempdir = ini_get('upload_tmp_dir');   //going wrong.
     $maxsize = ini_get('upload_max_filesize');
     //echo "http://lazyriver.on-rev.com/upload/{$file}" . "\r\n" .  
$_FILES['userfile']['size'] . "\r\n" . $_FILES['userfile']['type'] ;
	echo "http://lazyriver.on-rev.com/upload/{$newName}" . "\r\n" .  
"Format is " . $file . "\r\n" . "Size is " . $_FILES['userfile'] 
['size'] . "\r\n" . "Type is " . $_FILES['userfile']['type'] ;
	}
?>


This works perfectly to upload images from my app in the iPhone to the  
folder that the PHP is in. I don't understand it but it works. I would  
not even know where to begin to understand this or where to look with  
out opening the door to the thousands of pages with things I don't  
want to learn about PHP.
Now if this were to be able to be converted to iRev files and it works  
then I would really want to learn it. (The point of iRev I think).
