 Php 
  
  

  
$_files[' Photofile ': is an array of images to get uploaded
  
  

  
$uploadfile: Store Address
  
  

  
$ UploadFile  =  "d:/" . $_files[' photofile ' [' name ']; 
  
  

  
Copy ($_files[' photofile ' [' tmp_name '], $uploadfile);
  
  

  
echo "URL:  <a    href= ' http://localhost/'. $_files[' photofile ' [' Name']. "'   target=' _blank '>'. $_files[' photofile ' [' Name ']. "   a><br/> "; 
  
  

  
?> 
 
 

The above code is the basic PHP AJAX implementation of non-refresh image upload specific solutions.
