PHP image upload class with image display_PHP tutorial

This is a PHP file upload class with image display. In fact, it can be made into a function. But it is more fun to make it into a class. ~~~~
I should have used JS to verify the uploaded file type. But I was too lazy to do it. .








< form id="form1" name="upload" enctype="multipart/form-data" method="post" action="upload.php">



< ;/form>


Class upload
{
var $upload_name;
var $upload_tmp_address;
var $upload_server_name;
var $upload_filetype;
var $file_type;
var $file_server_address; =350; //To display the height of the image
var $upload_file_size;
var $upload_must_size= 50000; //Allow the size of the uploaded file, set it yourself
function upload_file()
{
$this->upload_name = $_FILES["file"]["name"]; //Get the name of the uploaded file
$this->upload_filetype = $_FILES["file"]["type"];
$this->upload_server_name = date("Y_m_dH_i_s").$this->upload_name;
$this->upload_tmp_address = $_FILES["file"]["tmp_name"]; //Get temporary Address
$this->file_type = array("image/gif","image/pjpeg"); //Types of files allowed to be uploaded
$this->upload_file_size = $_FILES["file"] ["size"]; //The size of the uploaded file
if(in_array($this->upload_filetype,$this->file_type))
{ if($this->upload_file_size < $this ->upload_must_size)
{
echo("Upload successful, thank you for your support");
$this->file_server_address = "D:usrwwwhtmlupload/".$this->upload_server_name;
Move_uploaded_file ($ this-& gt; upload_tmp_address, $ this- & gt; file_server_address); // Moles
echo ("& lt; IMG sg s RC = $ this-& gt; file_server_address width = $ this- & gt; image_w height = $this->image_h/>"); //Display image

}
else
{
echo("The file size is too large");
}
}
else
{
echo("This file type is not supported, please select again");
}

}

}
$dd = new upload;
$dd->upload_file();
?>
