What are some common pitfalls when using the str_split function in PHP?

One common pitfall when using the str_split function in PHP is that it splits the string into an array of individual characters by default, which may not be the desired outcome. To split the string into chunks of a specific length, you need to specify the chunk length as the second parameter in the str_split function.

// Splitting a string into chunks of a specific length
$string = "Hello World";
$chunkLength = 5;
$chunks = str_split($string, $chunkLength);

print_r($chunks);
