PHP crop image to fix width and height without losing dimension ratio

im looking to create thumbnails that has 100px by 100px dimension. i've seen many articles explaining the methods but most end up having the width!=height if the dimension ratio is to be kept.

for example, i have a 450px by 350px image. i would like to crop to 100px by 100px. if i were to keep the ratio, i would end up having 100px by 77px. this makes it ugly when im listing these images in a row and column. however, a image without dimension ratio will look terrible as well.

i've seen images from flickr and they look fantastic. for example:
thumbnail: http://farm1.static.flickr.com/23/32608803_29470dfeeb_s.jpg
medium size: http://farm1.static.flickr.com/23/32608803_29470dfeeb.jpg
large size: http://farm1.static.flickr.com/23/32608803_29470dfeeb_b.jpg

tks

To complete @SvenKoschnicke code, here is little tool to process other image formats:

$sourceProperties = getimagesize($imgSrc);

 $width = $sourceProperties[0];

 $height = $sourceProperties[1];

 switch ($sourceProperties[2]) {

 case IMAGETYPE_PNG:
        $myImage = imagecreatefrompng($imgSrc); 
        break;

  case IMAGETYPE_GIF:
        $myImage = imagecreatefromgif($imgSrc); 
        break;

  case IMAGETYPE_JPEG:
        $myImage = imagecreatefromjpeg($imgSrc); 
        break;
 }
