how to upload file of large size

Here is my code but it not work properly. I want to upload a file that is of size 50mb but fail to do so

<td><label for="file">Filename:</label></td>
								<input type="hidden" name="upload_max_filesize" value="30000000000000000" />
								<input type="hidden" name="max_input_time" value="30000" />
								<input type="hidden" name="max_execution_time" value="30000" />
								<input type="hidden" name="post_max_size" value="30000" />
								<input type="hidden" name="memory_limit" value="30000000000000000000000000" />								
								<td><input type="file" name="userfile" id="file" class="button"/></td>

move_uploaded_file($_FILES["userfile"]["tmp_name"], "../file/" . $filename)

PHP:

 

you have to increase the post_max_size in the php.ini

 

this will not work

 

this is not working i am increasing the value in post_max_size

 

Try changing both post_max_size and upload_max_filesize in your php.ini file. Optionally, you might also try increasing the memory_limit var (normally set to only 8MB) Let us know if this solves your problem

 

You Have To Increase it in a file called php.ini

thats only if u have shell access

you can try one of these solutions http://www.galaxyscripts.com/forum/index.php?showtopic=6
