The main target is the application on window.
1. The server to support APC expansion, without this extension, Baidu click Php_apc.dll, download an extension of expansion requirements php.5.2 above.
2. Configure APC configuration, restart Apache

The code is as follows Copy Code
Extension=php_apc.dll
apc.rfc1867 = On
Apc.max_file_size = 1000M
Upload_max_filesize = 1000M
Post_max_size = 1000M

Explain: As for the parameters to match how big, need to see the project needs apc.max_file_size, set up APC support upload file size, request Apc.max_file_size <=upload_max_filesize and Apc.max_ File_size <=post_max_size. You can implement APC support by restarting Apache.
3. Use Phpinfo () in the code to see if the APC extension is installed.
4. Here is the implementation code:
getprogress.php

The code is as follows Copy Code

<?php
Session_Start ();
if (Isset ($_get[' Progress_key ')) {
$status = Apc_fetch (' upload_ '. $_get[' Progress_key '));
Echo ($status [']/$status [' Total ']) *100;
}
?>
upload.php

$id = $_get[' id '];
?>

</form>
