What are the potential pitfalls of using explode in PHP to split a string into individual characters?

The potential pitfall of using explode in PHP to split a string into individual characters is that explode is designed to split a string into substrings based on a delimiter, not individual characters. To split a string into individual characters, you can use str_split instead. 

// Incorrect usage of explode to split a string into individual characters
$string = "hello";
$characters = explode("", $string);
print_r($characters); // This will not split the string into individual characters

// Correct way to split a string into individual characters using str_split
$string = "hello";
$characters = str_split($string);
print_r($characters); // This will output an array of individual characters: ['h', 'e', 'l', 'l', 'o']
