How do I replace \ within a string in PHP?

I am trying to mathtrans on my wiki. It uses Tex and I've been using LaTex up to now. Within matrices a new line in LaTex is designated with a \ but within Tex it is \cr. I have a few hundred wiki articles that may have an issue with this so I am altering the Math.php to do some simple string replacement. Right now I need \ replaced with \cr. Thanks
