PHP large file Upload progress bar implementation

Currently, I know two methods: one is to use the APC extension module written by RasmusLerdorf, founder of PHP, and the other is to use the uploadprogress extension module of PECL.

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 by referring to the official documentation. you can use the PECL module to install APC quickly and easily.

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.

Sample code:

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 }
