There are two arrays. It is necessary to display a list from the first array on the page, in which the elements of the second array will be highlighted, for example with a color. Probably it is necessary to read one array in a loop and compare, for example preg_match with the second array and if there is a coincidence - to allocate. Does anyone have a more beautiful solution?
