//Types that can be uploaded
$uptypes=array('image/jpg','image/jpeg','image/png','image/pjpeg','image/gif ',
'image/bmp','image/x-png');
?>
The file types allowed to be uploaded are:



$max_file_szie=2*pow(2,20); //The uploaded file is less than 2MB
$destination_folder='uploadimg/'; // Upload file saving path
if($_SERVER['REQUEST_METHOD']=='POST'){
 if(!is_uploaded_file($_FILES['upfile']['tmp_name'])){
 echo 'The picture does not exist! ';
 exit;
 }
 if($max_file_szie<$_FILES['upfile']['size']){
 echo 'The file is too big! ';
 exit;
 }
 if(!in_array($_FILES['upfile']['type'],$uptypes)){
 echo 'The file type does not match! '.$_FILES['upfile']['type'];
 exit;
 }
 if(!file_exists($destination_folder)){
 mkdir($destination_folder);
 }
 $filename=$_FILES['upfile' ]['tmp_name'];
 $image_size=getimagesize($filename);
 $pinfo=pathinfo($_FILES['upfile']['name']); //File path information
 $ftype=$pinfo[' extension']; //Old file extension
 $destination = $destination_folder.time().".".$ftype; //New file name
 if(file_exists($destination)&&$voerwrie !=true){
 echo 'The file with the same name already exists! ';
 exit;
 }
 //Move the uploaded file from the temporary folder to the specified directory
 if(!move_uploaded_file($filename,$destination)){
 echo 'An error occurred while moving the file! ';
 exit;
 }
 $pinfo=pathinfo($destination);
 $fname=$pinfo[basename];
 echo "Uploaded successfully< br>File name:
 ".$destination_folder.$fname."";
 echo 'Width:'.$image_size[0];
 echo 'Height:'.$image_size[1];
