What are some potential pitfalls to avoid when working with comma-separated values in PHP arrays and how can they be mitigated?

When working with comma-separated values in PHP arrays, a potential pitfall to avoid is accidentally including commas within the values themselves, which can lead to incorrect parsing. To mitigate this, you can use a different delimiter to separate values, such as a pipe (|) or semicolon (;), and then properly handle the parsing in your code. 

// Example of using pipe (|) as a delimiter for values in a string
$data = "John|Doe|30|New York";
$values = explode('|', $data);

print_r($values);
