Return first x paragraphs from a string

Question

How can I return the first x paragraphs from a string using PHP? They're seperated by \r\n but can be put into <p></p> tags if needed.

Answer 1

//split $s into paragraphs
$a = explode("\r\n", $s);

//extract the first $x paragraphs only
$a = array_slice($a, 0, $x);

//rejoin the paragraphs into a single string again
$s = implode('\r\n', $a);
