How to highlight a change in text?

Question

PHP

For example, there are two texts : the
first text
is "A hare came out of the fog, took out a knife from his pocket: I will cut, I will beat - with whom I will be friends"
The second text
"A hare came out of the fog, took out a carving knife for meat from his pocket: I will cut, I will beat - with whom will I be friends"
How to highlight the different text of the second option in relation to the first? It is necessary to wrap this piece of text, for example, in bold
"A hare came out of the fog, took out a carving knife for meat from his pocket: I will cut, I will beat - with whom I will be friends"
At the same time, there may be more than one changed sections. I will be happy with examples. Thanks in advance)
