How can special characters like "?" be handled effectively when using split() in PHP?

When using the split() function in PHP to split a string based on a delimiter, special characters like "?" can cause unexpected results or errors. To handle special characters effectively, you can use the preg_split() function with a regular expression pattern that escapes the special characters. This ensures that the split operation is performed correctly without any issues related to special characters.

$string = "Hello?World";
$delimiter = "/\?/"; // escape the "?" character with a backslash
$parts = preg_split($delimiter, $string);

print_r($parts);
