image_hwstring( int|string $width, int|string $height )

Retrieve width and height attributes using given width and height values.

Description

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.

Parameters

$width

(int|string) (Required) Image width in pixels.

$height

(int|string) (Required) Image height in pixels.

Return

(string) HTML attributes for width and, or height.
