Simple class for Uploading Files in PHP

Everyone is familiar with uploading files in php. While uploading files we have to deal with many things like , we have to check whether corresponding file format is valid, uploaded file exceed maximum size, giving specified name for files.etc. So here iam giving various functions within a class which can help you during your file uploading operation.
Copy the below code and paste it  in a file named Uploader.php and include in your library folder.
<?php

    class Uploader
    {
        private $destinationPath;
        private $errorMessage;
        private $extensions;
        private $allowAll;
        private $maxSize;
        private $uploadName;
private $seqnence;
        
        function __construct($path){
            $this->destinationPath  =   $path;
            $this->allowAll =   false;
        }
        
        function allowAllFormats(){
            $this->allowAll =   true;
        }
        
        function setMaxSize($sizeMB){
            $this->maxSize  =   $sizeMB * (1024*1024);
        }
        
        function setExtensions($options){
            $this->extensions   =   $options;
        }

USING Uploader.php class in Your Project

Consider you have a form like this:-
<form name="upload" method="post" action="upload.php" enctype="multipart/form-data">
<input type="file" name="txtFile"  size="40"/>
<input type="submit" name="submit"/>
</form>

After submitting the Image file, in the upload.php get the image file like this :-

   $absDirName =   dirname(dirname(__FILE__)).'/uploads';
            $relDirName =   '../uploads';
         $uploader   =   new Uploader($absDirName.'/');//set the target directory
            $uploader->setExtensions(array('jpg','jpeg','png','gif'));// setting the extension
            $uploader->setSequence('img');// setting image sequence
            $uploader->setMaxSize(10);// setting size limit
            if($uploader->uploadFile("txtFile")){
                 $image     =   $uploader->getUploadName(); //get uploaded image name
                }
