How to make a square image preview in PHP?

Question

PHP

You need to do like here with the authors, for example, I upload an image of 500x250, and I get 256x256 (or any other size, for example, 64x64)
Original image

And this is what we get

UPD.
If the height of the image is greater than the width, the length of the square is equal to the width, and if the width is greater, the length is equal to the height, and then the whole thing is increased or reduced to the desired size.

Answer 1

For example, use imagecopyresampled() .
To pre-determine the size of the original (and then find the maximum square area), you can use getimagesize() .
All business running around - 10~15 lines of code :)
