PHP file upload with progress bar (1/3)_PHP tutorial

Implementation
Generally speaking, there are two methods to implement upload progress bar using php tutorial:
1.apc extension (the author is the founder of php tutorial, php has added apc extension after 5.2)
2.pecl extension module uploadprogress
Whether it is apc or uploadprogress, you need to compile the source code tutorial, because the original php function cannot read the contents of the temporary folder. Let’s take a look at how to use it and the key code: apc implementation method:
1. Install apc
2. Configure php.ini and set the parameter apc.rfc1867=1
3. Key code:

if ($_server['request_method'] == 'post') { //Upload request
$status = apc_fetch('upload_' . $_post['apc_upload_progress']);
$ status['done'] = 1;
echo json_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']);
echo json_encode($status);
exit ;
}

Uploadprogress implementation method:
1. Use pecl to install uploadprogress
2. Set uploadprogress.file.filename_template = “/tmp/upd_%s in php.ini .txt"
3. Key code:

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
}
}
