What are some best practices for choosing between explode() and preg_split() for splitting strings in PHP?

When choosing between explode() and preg_split() for splitting strings in PHP, it is important to consider the complexity of the delimiter pattern. If the delimiter is a simple character or string, explode() is typically faster and more efficient. However, if the delimiter is a regular expression pattern, preg_split() should be used for more flexibility and control.

// Using explode() for splitting a string by a simple delimiter
$string = "apple,banana,orange";
$fruits = explode(",", $string);

// Using preg_split() for splitting a string by a regular expression pattern
$string = "apple,banana,orange";
$fruits = preg_split("/,|;/", $string);
