Can I split a text variable into two?

[DrMarie]

I'd like to take a chunk of text and search for a particular string or phrase and then split the text here into two chunks. For example:

$phrase="This is a test.bbbNew phrase starts here"

I'd like to be able to parse $phrase and when it comes to bbb have it recognize that this is a new phrase so that we end up with
$phrase1="This is a test." and
$phrase2="New phrase starts here"

Thanks!

$phrases = explode('bbb', $phrase);
