First make your form something like the following:

 Help with Code Tags 
 html Syntax (Toggle Plain Text) 
<form enctype="multipart/form-data" action="uploader.php" method="POST">
Upload File:
<input name="Upload Saved Replay" type="file" accept="image/gif, image/jpeg"/><br />
Below line is the essential line.
<input type="hidden" name="MAX_FILE_SIZE" value="200000000" />
<input type="submit" value="Upload File" />
</form>
<form enctype="multipart/form-data" action="uploader.php" method="POST">
Upload File:
<input name="Upload Saved Replay" type="file" accept="image/gif, image/jpeg"/><br />
Below line is the essential line.
<input type="hidden" name="MAX_FILE_SIZE" value="200000000" />
<input type="submit" value="Upload File" />
</form>

And in the php side, add the following to the top of your page:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?
ini_set('upload_max_filesize','200M');
<?
ini_set('upload_max_filesize','200M');

Try not to bump 10 year old threads as it can be really annoying.

Thanks But I've solved this issue..........
Use $_SERVER['CONTENT_LENGTH'] after trying to upload file. This variable returns size of uploaded file, even if upload failed

I am actually still having the issue I can change the settings in my ini but what I am trying to do is validate all the information about the uploaders file before they actually upload it else they spend maybe 5 minutes or so uploading the file to be told it has the wrong extension...

This is a big issue and has ground the work down to a halt.

It is possible to use html to validate the file format simply by using the accept= method in the upload field. Below is an example that only accepts gif files and jpeg files:

 Help with Code Tags 
 html Syntax (Toggle Plain Text) 
<input name="Upload Saved Replay" type="file" accept="image/gif, image/jpeg"/>
<input name="Upload Saved Replay" type="file" accept="image/gif, image/jpeg"/>
