If n is greater than the length of the string then most implementations return the whole string (exceptions exist – see code examples). Note that for variable-length encodings such as UTF-8, UTF-16 or Shift-JIS, it can be necessary to remove string positions at the end, in order to avoid invalid strings.
The simplest operation is taking a substring, a snippet of the string taken at a certain offset (called an "index") from the start or end. There are a number of legacy templates offering this but for new code use {{#invoke:String|sub|string|startIndex|endIndex}}. The indices are one-based (meaning the first is number one), inclusive (meaning ...

Some other byte may be used as end of string instead, like 0xFE or 0xFF, which are not used in UTF-8. UTF-16 uses 2-byte integers and as either byte may be zero (and in fact every other byte is, when representing ASCII text), cannot be stored in a null-terminated byte string.

Comments in PHP can be either in C++ style (both inline and block), or use hashes. PHPDoc is a style adapted from Javadoc and is a common standard for documenting PHP code. Starting in PHP 8, the # sign can only mean a comment if it's not immediately followed by '['. Otherwise, it will mean a function attribute, which runs until ']':
