PHP preg_replace: limit replacements

Question

Im using this piece of code:

<?php $newstring = preg_replace("/[\n\r]/", "<br />" , $googlemapsbox_text); echo $newstring; ?>

To replace the \n's. What I would like to achieve: limit the amount of <br /> per line, so when preg_replace finds more than 1 \n per line, they ALL should be replaced with ONE <br />.

I hope my question is clear to you, sorry for the weird English

This should work:

preg_replace("/[\n\r]+/", "<br />", // rest of your code
=====================^ add a + there on your regex
