What is the difference between split() and explode() functions in PHP when splitting a string by newline characters?

When splitting a string by newline characters in PHP, the main difference between the split() and explode() functions is that split() is deprecated as of PHP 7.0 and removed in PHP 8.0, while explode() is the recommended function to use. explode() specifically splits a string by a specified delimiter, such as a newline character, and returns an array of substrings.

// Using explode() function to split a string by newline characters
$string = "Hello\nWorld\nThis\nIs\nA\nTest";
$lines = explode("\n", $string);

// Output each line
foreach ($lines as $line) {
    echo $line . "\n";
}
