How can one ensure that the split function in PHP does not mistakenly split a string at the letter "n"?

To ensure that the split function in PHP does not mistakenly split a string at the letter "n", you can use a regular expression pattern that specifies that the split should only occur at spaces. This can be achieved by using the preg_split function with the appropriate regular expression pattern. 

$string = "Hello, World! This is a sentence.";
$words = preg_split('/\s+/', $string);
print_r($words);
