PHP implements real-time upload progress bar function with APC, APC progress bar

PHP does not have a real-time upload progress bar function, if you want to have this feature we will generally use Ajax to implement, but PHP provides an APC, it can be configured with PHP to implement the upload progress bar function.
The main target is the application on the window.
1. The server to support APC extension, without this extension, download a scale extension requires more than php.5.2.
2. Configure the APC configuration to restart Apache
The code is as follows

Extension=php_apc.dll
apc.rfc1867 = On
Apc.max_file_size = 1000M
Upload_max_filesize = 1000M
Post_max_size = 1000M
Note: As for the parameters to match how big, depends on the project needs apc.max_file_size, set the size of the upload file supported by APC, requires apc.max_file_size<=upload_max_filesize and apc.max_file_size <=post_max_size. Rebooting Apache will enable APC support.
3. Use Phpinfo () in the code to see if the APC extension is installed.
4. The following is the implementation code:
getprogress.php
The code is as follows

<?php session_start (); if (Isset ($_get[' Progress_key ')) {  $status = apc_fetch (' upload_ '. $_get[' Progress_key ']);  Echo ($status [' Current ']/$status [' Total ']) *100; }?> upload.phpphp code<?php  $id = $_get[' id ');?>  

target.php
The code is as follows

<?php  Set_time_limit (+), if ($_server[' Request_method ']== ' POST ') {  move_uploaded_file ($_files["Test_ File "[" Tmp_name "],  dirname ($_server[' script_filename '])." /uploadtemp/". $_files["Test_file" ["name"]);//uploadtemp folder is located in the same directory as this script  echo "
Upload successful

index.php
The code is as follows

<?php  $id = MD5 (Uniqid (rand (), true));?>  Upload Progress       

     
    

The above is to share with you PHP using APC to achieve real-time upload progress bar function, I hope that everyone's learning is helpful.
