1. The class file name is: upclass.php

<?php class upclass{Public $previewsize = 0.125;  Preview picture proportions Public $preview = 0;  Whether to generate a preview, is 1, no 0 public $datetime;  Random number public $ph _name;  Upload picture filename public $ph _tmp_name;  Picture Temp file name public $ph _path= "./userimg/";  Upload File Store path public $ph _type;  Picture type public $ph _size;  Picture size public $imgsize; Upload picture size, used to judge the display ratio public $al _ph_type=array (' image/jpg ', ' image/jpeg ', ' image/png ', ' image/pjpeg ', ' image/gif ', ' image  /bmp ', ' image/x-png ');  Allow upload picture type public $al _ph_size=1000000;
 Allow upload file size function __construct () {$this->set_datatime ();
 function Set_datatime () {$this->datetime=date ("Ymdhis");
 }//Get file type function Get_ph_type ($phtype) {$this->ph_type= $phtype; }//Get file Size function get_ph_size ($phsize) {$this->ph_size= $phsize. "
 <br> ";
  //Get upload Temp file name function get_ph_tmpname ($tmp _name) {$this->ph_tmp_name= $tmp _name;
 $this->imgsize=getimagesize ($tmp _name); //Get the original filename function get_ph_name ($phname) {$this->ph_name= $this->ph_path. $thiS-&GT;DATETIME.STRRCHR ($phname, "."); STRRCHR gets the point where the file was last seen//$this->ph_name= $this->datetime.strrchr ($phname, ".");
 STRRCHR gets the point where the file was last seen return $this->ph_name;
  //Judge upload file to store directory function Check_path () {if (!file_exists ($this->ph_path)) {mkdir ($this->ph_path); }//To determine if the upload file exceeds the allowed size function check_size () {if ($this->ph_size> $this->al_ph_size) {$this->showerror ("Upload
  Picture more than 2000KB "); }///Judge file type function Check_type () {if (!in_array ($this->ph_type, $this->al_ph_type)) {$this->showerror ("
  Upload picture type error "); }//Upload picture function Up_photo () {if (!move_uploaded_file ($this->ph_tmp_name, $this->ph_name)) {$this->shower
  Ror ("Error uploading file"); }//Picture preview function Showphoto () {if ($this->preview==1) {if ($this->imgsize[0]>2000) {$this->imgsi
       ze[0]= $this->imgsize[0]* $this->previewsize;
   $this->imgsize[1]= $this->imgsize[1]* $this->previewsize; Echo ("ph_name}\) width=\ "{$this->imgsize[' 0 ']}\" height=\ "{$this->imgsize[' 1 ']}\" > "); }///Error prompt function ShowError ($errorstr) {echo "<script language=javascript>alert (' $errorstr '); location= ' Javas
  Cript:history.go ( -1) ';</script> ';
 Exit ();
  function Save () {$this->check_path ();
  $this->check_size ();
  $this->check_type ();
  $this->up_photo ();
 $this->showphoto ();

 }}?>
