How to crop image without loosing any portion of uploaded image using php?

Well, In my site I am trying to crop image with following php function : 

function image_resize($target, $newcopy, $w, $h, $ext) {
    list($w_orig, $h_orig) = getimagesize($target);
    $scale_ratio = $w_orig / $h_orig;
    if (($w / $h) > $scale_ratio) {
           $w = $h * $scale_ratio;
    } else {
           $h = $w / $scale_ratio;
    }
    $img = "";
    $ext = strtolower($ext);
    if ($ext == "gif"){ 
    $img = imagecreatefromgif($target);
    } else if($ext =="png"){ 
    $img = imagecreatefrompng($target);
    } else { 
    $img = imagecreatefromjpeg($target);
    }
    $tci = imagecreatetruecolor($w, $h);
    $backgroundColor = imagecolorallocate($tci, 255, 255, 255);    
    imagefill($tci, 0, 0, $backgroundColor);
    // imagecopyresampled(dst_img, src_img, dst_x, dst_y, src_x, src_y, dst_w, dst_h, src_w, src_h)
    imagecopyresampled($tci, $img, 0, 0, 0, 0, $w, $h, $w_orig, $h_orig);
    if ($ext == "gif"){ 
        imagegif($tci, $newcopy);
    } else if($ext =="png"){ 
        imagepng($tci, $newcopy);
    } else { 
        imagejpeg($tci, $newcopy, 84);
    }
}

But it's not working what I exactly want.

For example : I have a image which size is : 720 x 478. When I resize it with this function (I can set the width and height in function call) it's cropping the image based on width. For e.g. I am calling it like that: 

image_resize($file_destination, "../users_avator/ppic_$file_new_name", 200, 200, $file_ext);

It's saved the image with 200 x 132 size. but which I don't want

I want to crop the image exactly 200 x 200 size but without cutting any portion of the image. Like :

I see a website called cozymeal.com When I upload the same image in the profile section which size is 720 x 478 it's magically crop the image size to 200 x 200 without cutting any portion of the image.

Original Image :

My cropping result :

Cozymeal cropping result :

My question is How can I fix my function / crop any images like this cozymeal.com cropping system ? I mean custom size without loosing any image portion.

Funny, I'm actually working at Cozymeal. We get this feature with our CDN cloudinary but you can use this library if you want to crop images as you want: https://github.com/avalanche123/Imagine

All the doc is inside the plugin

If you don't feel comfortable with this library you can use one of the following: https://github.com/ziadoz/awesome-php#imagery

Good luck :)
