Highlight changes

[EchoFool]

Hey,

 

Say i had two strings assigned to different variables like

$var = 'Hello there, how are you ?';
$var2 = 'Hello there, how are you today?';

 

I want to get a function automatically highlight whats different between the two by - say for example highlighting the added words in a red font.

 

So like the result would show (after comparison)

 

Hello there, how are you today?

 

Is there a built in function for such a thing or is this a make your own function moment?

This is called a "diff".  There's no php built-in, but there is a PEAR package named text_diff as well as other packages based on it, you can find out there.
