'Cut the string to particular length and preserve whole words

What would be the best way to, given a string $s and character limit $l, cut the $s so that whole words are preserved.

Example:

$s = 'Hello World.';
$l = 7;

function shorten( $a, $b ) { ... }
// Function should return 'Hello'

I've tried doing it with wordwrap( $s, $l, ';;;' ); and then substr( $s, strpos( ';;;', $l ) ); but that seems awful.

preg_replace will help you here:

$strings = [
  'Word',
  'Length.',
  'Hello World.',
  'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
];
$length = 7;
foreach( $strings as $string ){

  print 
    $string
    . ' => '
    . preg_replace("/(.{{$length}}[^\s]*).*/s", "$1", $string)
    . "\n";
}

Output:

Word => Word
Length. => Length.
Hello World. => Hello World.
Lorem ipsum dolor sit amet, consectetur adipiscing elit. => Lorem ipsum
