PHP Upload File - right code but can't find the file/path - php

Question

First question for quite a while. Essentially, I've got some code that (1) works perfectly in the live environment, (2) used to work in my home OSX environment but (3) doesn't work now.
The HTML:
<form id="upload_form" action="php/upload_class_list.php" method="post" accept-charset="UTF-8" enctype="multipart/form-data" target="upload_target" >
<label>File:</label>
<input name="myfile" type="file" size="35" />
<input id="upload_submit" type="submit" value="Upload" />
<iframe id="upload_target" name="upload_target" style="width:0;height:0;border:0px solid #fff;"></iframe>
</form>
The PHP file:
$destination_path = getcwd().DIRECTORY_SEPARATOR;
$result = 0;
$target_path = $destination_path . basename( $_FILES['myfile']['name']);
if(#move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
...
}
sleep(1);
?>
<script language="javascript" type="text/javascript">top.upload_class_list(<?php echo $result; ?>);</script>
The script fires at the end, but the PHP code doesn't enter the if (in the local development environment) and so $result remains at 0.
It seems it's not picking up the path of the file to be uploaded; $destination_path points to the folder where the PHP file is located, and not where the file is found.
I think my local environment may have stopped working when I changed to Mountain Lion and rebuilt the PHP setup.
What is missing to stop the file being found?
Let me emphasise: exactly the same code works fine in my live Hostmonster setup, so it's an environment problem, I guess :)
Thanks.

if(#move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
...
}

What makes you think the problem is the file being found? Maybe the file is found, but what fails is the move... for example because the Web server has no permissions to write into the target_path.
You can check:
$src = $_FILES['myfile']['tmp_name'];
$dst = $target_path;
if (!file_exists($src))
die("Okay, the file is actually not found");
if (!is_readable($src))
die("Very bad hosting juju. The file was uploaded but I can't read it?!?");
if (!is_writeable($destination_path))
die("As expected, you can't upload a file here. This is a good thing.");
#touch($dst);
if (!file_exists($dst))
die("So call me a Marine, the file SHOULD be writeable (which is not so good), and yet I could not write it! Perhaps disk full? User overquota? Some weird security setup?");
The reason why it's a good thing is because that directory holds executable PHP files, and if anyone could upload a PHP file in there, well, that would be a major security hole.
You can set aside another directory and make it writeable (remember to put in there a .htaccess or other system to prohibit read/execute access from the outside).

Answer 2

may be this
<?php
$target = "upload/";
$target = $target . basename( $_FILES['uploaded']['name']) ;
$ok=1;
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo "The file ". basename( $_FILES['uploaded']['name']). " has been uploaded";
}
else {
echo "Sorry, there was a problem uploading your file.";
}
?>
