Image processing - How to enlarge the tile size of small images in PHP?

I want to be able to enlarge a small picture into a large picture like the Windows desktop, by filling it into the large size through tiles. How should I do it? I have been using Imagick for a long time and still can't find a clue.

Imagick has a Montage tool.
Usage is as follows:

<code>To tile a set of images, allowing ImageMagick to pick the layout for you:


$ montage *.jpg out.jpg
To tile a set of 7 images, arranged in a single row:


$ montage *.jpg -tile 7x1 out.jpg
To tile a set of 5 images, arranged in a single column:


$ montage *.jpg -tile 1x5 out.jpg
To tile a set of 10 images, arranged in two rows:


$ montage *.jpg -tile 5x2 out.jpg
To specify that only a spacing of 2 pixels be used between images in the above setting:


$ montage *.jpg -tile 5x2 -geometry +2+2 out.jpg
Tried with: ImageMagick 6.6.9-7 and Ubuntu 12.04</code>
