with this code, you can create an upload page that combines HTML and PHP easily.

Step 1 : Create one page with HTML content

HTML Code:

<html>  
<head>  
<title>Upload</title>  
</head>  
<body>  
<h1>Upload</h1>  
<form enctype="multipart/form-data" action="upload.php" method="post">  
<input type="hidden" name="MAX_FILE_SIZE" value="1000000"> File:  
<input name="userfile" type="file">  
<input type="submit" value="Upload">  
</form>  
</body>  
</html>

Step 2 : Create file upload.php with content :

HTML Code:

<?php  
// $userfile is where file went on webserver  
$userfile = $HTTP_POST_FILES['userfile']['tmp_name'];  
// $userfile_name is original file name  
$userfile_name = $HTTP_POST_FILES['userfile']['name'];  
// $userfile_size is size in bytes  
$userfile_size = $HTTP_POST_FILES['userfile']['size'];  
// $userfile_type is mime type e.g. image/gif  
$userfile_type = $HTTP_POST_FILES['userfile']['type'];  
// $userfile_error is any error encountered  
$userfile_error = $HTTP_POST_FILES['userfile']['error'];  

// userfile_error was introduced at PHP 4.2.0  
// use this code with newer versions  

if ($userfile_error > 0) {  
echo 'Problem: ';  
switch ($userfile_error)  
{ case 1:  
echo 'File exceeded upload_max_filesize';  
break;  
case 2:  
echo 'File exceeded max_file_size';  
break;  
case 3:  
echo 'File only partially uploaded';  
break;  
case 4:  
echo 'No file uploaded';  
break;  
}  
exit;  
}  

// put the file where we'd like it  
$upfile = '/uploads/'.$userfile_name;  

// is_uploaded_file and move_uploaded_file  
if (is_uploaded_file($userfile))  
{  
if (!move_uploaded_file($userfile, $upfile))  
{  
echo 'Problem: Could not move file to destination directory';  
exit;  
}  
} else {  
echo 'Problem: Possible file upload attack. Filename: '.$userfile_name;  
exit;  
}  
echo 'File uploaded successfully<br /><br />';  

// show what was uploaded  
echo 'Preview of uploaded file contents:<br /><hr />';  
echo $contents;  
echo '<br /><hr />';  
?>

Note :line: $upfile = '/uploads/'.$userfile_name; Folder of files have been stored, you can change it depending on your ideas

Another form of Upload file, you can choose file that you want to upload optionally

Create file upload.php with contents

HTML Code:

<?php  
  //Define some variables  
      $dir = "path/where/you/want/to/upload/files/"; //Bạn nên thay ðổi ðýờng dẫn cho phù hợp  
    //Kiều file, Gif, jpeg, zip ::bạn có thể sửa ðổi nếu thích  
      $types = array("image/gif","image/pjpeg","application/x-zip-compressed");  
      
//Check to determine if the submit button has been pressed  
    if(isset($_POST['submit'])){  

//Shorten Variables  
     $tmp_name = $_FILES['upload']['tmp_name'];  
     $new_name = $_FILES['upload']['name'];  

//Check MIME Type  
    if (in_array($_FILES['upload']['type'], $types)){  
                     
         //Move file from tmp dir to new location  

        move_uploaded_file($tmp_name,$dir . $new_name);  
            
        echo "{$_FILES['upload']['name']} was uploaded sucessfully!";                                          
            
    }else{  
                 
    //Print Error Message  

     echo "<small>File <strong><em>{$_FILES['upload']['name']}</em></strong> Was Not Uploaded!</small><br />";  
       
    //Debug  
   $name =  $_FILES['upload']['name'];  
   $type =    $_FILES['upload']['type'];  
   $size =    $_FILES['upload']['size'];  
   $tmp =     $_FILES['upload']['name'];  
      
   echo "Name: $name<br/ >Type: $type<br />Size: $size<br />Tmp: $tmp";  
               
    }  
        
    }        
        
else{        
        
    echo 'Could Not Upload Files';  
        
}  
        ?>  
            
    <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">  
        
      <fieldset>  
              <legend>Upload Files</legend>  
                                            
          <input type="file" name="upload" />  
</fieldset>  
<input type="submit" name="submit" value="Upload Files" />  
</form>
