What potential pitfalls are associated with using deprecated functions like split() in PHP code?

Using deprecated functions like split() in PHP code can lead to compatibility issues with newer versions of PHP, as these functions may be removed in future updates. To avoid this, it is recommended to use alternative functions like explode() or preg_split() which provide similar functionality but are not deprecated.

// Using explode() as an alternative to split() function
$string = "Hello, World";
$parts = explode(", ", $string);
print_r($parts);
