How to select only first few words not lines of sentences?

Question

I am using the following snippet:

 implode(' ', array_slice(explode(' ', $sentence), 0, 10));

The problem is that if there are two or 3 lines than it repeats the function and shows 10 words or etc per line.

How can i do it so it only selects the first 10 words from the first sentence and not repeat itself.

Answer 1

$lines = split("[\n|\r]", $sentence);
implode(' ', array_slice(explode(' ', $lines[0]), 0, 10));

First split into many lines, then do your action on only the first line.

Answer 2

Make sure that $sentence only contains the first line of whatever you're feeding it, before it ever gets to this line of code.
