 str_starts_with() checks if $haystack begins with $needle. It accomplishes this by comparing each character in $haystack with the corresponding character in $needle. If any of the characters do not match, it will return false. str_ends_with() does the same thing except in reverse: it starts at the end of both $haystack and $needle and compares each character in $haystack to the corresponding character in $needle. str_starts_with() checks if $haystack begins with $needle.
