File Upload progress bar PHP Tutorial Code
This article is the use of PHP a plugin instance mail php file upload progress bar function, the method is relatively simple, because there are components, so long as the person's meaning can be used to sample PHP large file upload function.
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
}
