How can I reduce the quality of an image using PHP ? 

upload_mode = @$this->setting->upload_mode?:'file';
            $upload_path = @$this->setting->upload_path?:'uploads/';

            $file               = Request::file($name);
            $fm                 = array();
            $fm['name']         = $_FILES[$name]['name'];                   
            $fm['ext']          = $file->getClientOriginalExtension();
            $fm['size']         = $_FILES[$name]['size'];
            $fm['content_type'] = $_FILES[$name]['type'];

            if($upload_mode=='database') {
                $fm['filedata']     = file_get_contents($_FILES[$name]['tmp_name']);
                DB::table('cms_filemanager')->insert($fm);
                $id_fm              = DB::getPdo()->lastInsertId();
                DB::table('cms_filemanager')->where('id',$id_fm)->update(['id_md5' =>md5($id_fm)]);
                $filename           = 'upload_virtual/files/'.md5($id_fm).'.'.$fm['ext'];
            }else{
                if(!file_exists($upload_path.date('Y-m'))) {
                    if(!mkdir($upload_path.date('Y-m'),0777)) {
                        die('Gagal buat folder '.$upload_path.date('Y-m'));
                    }

GD is an open source code library for the dynamic creation of images by programmers. GD is written in C, and "wrappers" are available for Perl, PHP and other languages. GD creates PNG, JPEG and GIF images, among other formats. GD is commonly used to generate charts, graphics, thumbnails, and most anything else, on the fly.

Code to reduce file size for the image:

<?php 
    function compress($source, $destination, $quality) {

        $info = getimagesize($source);

        if ($info['mime'] == 'image/jpeg') 
            $image = imagecreatefromjpeg($source);

        elseif ($info['mime'] == 'image/gif') 
            $image = imagecreatefromgif($source);

        elseif ($info['mime'] == 'image/png') 
            $image = imagecreatefrompng($source);

        imagejpeg($image, $destination, $quality);

        return $destination;
    }

    $source_img = 'source.jpg';
    $destination_img = 'destination .jpg';

    $d = compress($source_img, $destination_img, 90);
 ?>
$d = compress($source_img, $destination_img, 90);
