How can regular expressions be effectively utilized in PHP to detect word boundaries and limit word length?
Regular expressions can be used in PHP to detect word boundaries by using the `\b` anchor. To limit word length, you can use the `\w{1,}` pattern to match words of a specific length. By combining these two techniques, you can effectively detect word boundaries and limit word length in PHP.
$text = "This is a sample text with words of varying lengths";
$wordLengthLimit = 5;
preg_match_all("/\b\w{1,$wordLengthLimit}\b/", $text, $matches);
foreach ($matches[0] as $match) {
echo $match . "\n";
}
