Currently, I know two methods: one is to use the APC extension module written by Rasmus lerdorf, founder of PHP to implement (http://pecl.php.net/package/apc ), another way is to use the PECL extension module uploadprogress implementation (http://pecl.php.net/package/uploadprogress) I here are two examples of implementation respectively for reference, more flexible application according to their own needs to modify.

APC implementation method: Install APC. Refer to the official documentation for installation. You can use the PECL module for quick and simple installation.
Configure PHP. ini and set the parameter APC. rfc1867 = 1 to enable APC to support the upload progress bar function, which is described in the APC source code instructions.
Code Example:
If ($ _ server ['request _ method'] = 'post') {// upload request
$ Status = apc_fetch ('upload _ '. $ _ post ['apc _ upload_progress']);
$ Status ['done'] = 1;
Echo json_encode ($ status); // Ajax call output to the user's page. Please find the relevant documentation
Exit;
} Elseif (isset ($ _ Get ['ss SS _ key']) {// read the upload progress
$ Status = apc_fetch ('upload _ '. $ _ Get ['ss SS _ key']);
Echo json_encode ($ status );
Exit;
} Else {
// Other code, such as uploading a form
}
Implementation of the uploadprogress module:

Use the PECL module Installation Method to install this module
Set uploadprogress. file. filename_template = "/tmp/upd_%s.txt" in PHP. ini"
Sample 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
} Else {
// Upload Failed
} Else {
// Upload Error

} Elseif (! Empty ($ _ Get ['sessid ']) {
Header ("expires: Mon, 26 Jul 1997 05:00:00 GMT ");
Header ("last-modified:". gmdate ("D, D m y h: 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 {
// Display the upload form
}
