PHP File upload progress bar specific implementation Method _php tutorial

When we write the file upload code, we also need to consider an important implementation function, that is the file upload required progress bar. Now I knowHere are two examples to be implemented separately for reference, more flexible applications to modify according to their own needs.

APC 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

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

code example:

 

  
if ($_server[' request_method ' = = ' POST ') {//Upload request
  
    $ Status  =  Apc_fetch  (' Upload_ '. $_post[' apc_upload_progress '); 
  
$status [' done '] = 1;
  
echo Json_encode ($status); Output to Ajax calls in the user-side page, please find the relevant documents yourself
  
Exit
  
} elseif (Isset ($_get[' Progress_key ')) {//Read upload Progress
  
    $ Status  =  Apc_fetch  (' Upload_ '. $_get[' Progress_key '); 
  
echo Json_encode ($status);
  
Exit
  
} else {
  
Other code, such as uploading a form, etc.
  
}
 

Uploadprogress Module Implementation method:

Implementation of the PHP file upload progress bar for installing the module using the PECL module installation method

PHP.ini inside set uploadprogress.file.filename_template = "/tmp/upd_%s.txt"

code example:

 

  
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, 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 {
  
Show Upload Form
  
}
 

These are the two types of PHP files that we introduced to upload progress bar specific methods.
