PHP turn comma into a <br />

Question

I do know that php can turn a newline into a <br /> using nl2br(), but is there a way that it can turn a comma (,) into a <br />?

For instance on an HTML page a user enters a bunch of words that are separated by a comma. He then submits it, it gets sent to a PHP file like normal and instead of the data getting sent right into the database, it goes through some kind of function to replace the commas with <br />.

So if I were to show the data on an HTML page, each thing they entered in that was separated by a comma is now separated by a newline/line break?

Answer 1

You can use a str_replace() to replace any string by another, so also a comma with a <br />:

$output = str_replace(',', '<br />', $input);

Answer 2

$values = str_replace( ',', '<br />', $values );

Answer 3

$output = str_replace(',', "\n", $input);

Answer 4

I think php.net : str_replace is what you need.
