There are two ways I know now, one is to use the APC extension module written by PHP's founder Rasmus Lerdorf (HTTP://PECL.PHP.NET/PACKAGE/APC), Another way to do this is to use the PECL extension uploadprogress implementation (http://pecl.php.net/package/uploadprogress) I'll give you two examples to implement separately for reference, more flexible applications to modify according to their own needs.

APC Implementation method:

Install APC, refer to the Official document installation, you can use the Pecl module installation method quick and simple, here does not explain

Configure the php.ini, set the parameter apc.rfc1867=1, enable APC to support the upload progress bar function, in the APC source code document contains the description

PHP File Upload progress bar Implementation method: Install APC, refer to the Official document installation, you can use the Pecl module installation method quick and simple, here does not explain the configuration php.ini, set the parameters apc.rfc1867=1, so that APC support the upload progress bar function, In the APC source code documentation, there are examples of the codes:

if ($_server[' Request_method ']== ' post ') {//Upload request
$status =apc_fetch (' upload_ ' $_post[' apc_upload_progress ');
$status [' Done ']=1;
Echojson_encode ($status);//output to the user-side page Ajax calls, related documents please find yourself
Exit
}elseif (Isset ($_get[' Progress_key ')) {//Read upload Progress
$status =apc_fetch (' upload_ ' $_get[' Progress_key ');
Echojson_encode ($status);
Exit
}else{
Other code, such as uploading a form, etc.
}
Uploadprogress Module Implementation method: Install the module using the PECL module installation method php file upload progress bar implementation method PHP.ini inside Set uploadprogress.file.filename_template = "/tmp/ Upd_%s.txt "

if ($_server[' Request_method ']== ' post ') {
if (Is_uploaded_file ($_files[' upfile ' [' tmp_name '])) {
$upload _dir= ' your_path/';
$ext =strrchr ($_files[' video ' [' Name '], '. ');
$sessid =$_post[' Upload_identifier '];
$tmpfile = $upload _dir. $sessid;
$sessfile = $upload _dir. $sessid. $ext;
if (Move_uploaded_file ($_files[' upfile ' [' tmp_name '], $tmpfile)) {
Upload successful
}else{
Upload failed
}else{
Upload Error

}elseif (!empty ($_get[' sessid ')) {
Header ("Expires:mon,26jul199705:00:00gmt");
Header ("last-modified:". Gmdate ("D,dmyh:i:s"). " GMT ");
Header ("Cache-control:no-store,no-cache,must-revalidate");
Header ("Cache-control:post-check=0,pre-check=0′,false");
Header ("Pragma:no-cache");
Header ("content-type:text/html;charset=utf-8′");

$unique _id=$_get[' sessid '];
$uploadvalues =uploadprogress_get_info ($unique _id);

if (Is_array ($uploadvalues)) {
echo Json_encode ($uploadvalues);
}else{
Read progress failed, additional processing logic
}

}else{
Show Upload Form
}
