How to implement the php file upload progress bar: install apc, refer to the official documentation for installation, you can The installation method using the pecl module is quick and simple. There is no description here of configuring php.ini. Set the parameter apc.rfc1867=1 to enable apc to support the upload progress bar function.

if ($_server['request_method']=='post'){//Upload request
$status=apc_fetch('upload_'.$_post['apc_upload_progress']);
$status['done'] =1;
echojson_encode($status);//Output to the ajax call in the client page, please find relevant documents yourself
exit;
}elseif(isset($_get['progress_key']) ){//Read upload progress
$status=apc_fetch('upload_'.$_get['progress_key']);
echojson_encode($status);
exit;
}else{
//Other codes, such as upload forms, etc.
}
Uploadprogress module implementation method: Use the pecl module installation method to install the module's php file upload progress bar implementation method. Set uploadprogress.file.filename_template = in php.ini "/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{
//Reading progress failed, additional processing logic
}

}else{
//Display upload form
}
