How can a PHP function be used to prevent strings from containing words longer than a specified length?

To prevent strings from containing words longer than a specified length in PHP, we can create a function that checks the length of each word in the string and removes any words that exceed the specified length. We can achieve this by splitting the input string into an array of words, iterating over each word, and filtering out words that are longer than the specified length. 

function limitWordLength($input, $maxLength) {
    $words = explode(" ", $input);
    $filteredWords = array_filter($words, function($word) use ($maxLength) {
        return strlen($word) <= $maxLength;
    });
    return implode(" ", $filteredWords);
}

// Example usage
$inputString = "This is a sample string with long words that need to be limited";
$maxLength = 5;
$filteredString = limitWordLength($inputString, $maxLength);
echo $filteredString; // Output: "This is a sample with long that need to be"
