How to return just first-line from a multi-line string of text?

[gouldtv]

I've been looking through the manual for string commands, and I haven't had success in determining the proper call for this, if there is one:

 

Let's say I have a text string with hard-carriage returns in it:

 

"The lazy brown fox ran down the road

to the store and bought some eggs

to bake a cake and serve dinner

for all his friends."

 

So if that string value is in "x", how can I tell it to return JUST the first line:

 

"The lazy brown fox ran down the road"

<?php

$string = 'The lazy brown fox ran down the road
to the store and bought some eggs
to bake a cake and serve dinner
for all his friends.';

$string = explode("\n", $string);

echo $string[0];  // = 'The lazy brown fox ran down the road'.

?>
