image_hwstring()

image_hwstring() — Retrieves width and height attributes using given width and height values. Both attributes are required in the sense that both parameters must have a value, but are optional in that if you set them to false or null, then they will not be added to the returned string. You can set the value using a string, but it will only take numeric values. If you wish to put ‘px’ after the numbers, then it will be stripped out of the return.

Inputs: $width (int|string): Image width in pixels. $height (int|string): Image height in pixels.

Returns string: HTML attributes for width and, or height.
