Description:
------------
It would be really useful to have standard functions:
  str_ends()  and str_begins()

These are trivial to implement, but the use for them is so extremely common that they'd be a helpful addition to the standard library. It's also not quite obvious to beginners how to do it - especially for str_ends().
For comparison, Javascript has string.startsWith() and string.endsWith()

Examples below. Thank you for your consideration and your time.

Test script:
---------------
function str_ends($string,$end){
	return (substr($string,-strlen($end),strlen($end)) === $end);
}
	
function str_begins($string,$start){
	return (substr($string,0,strlen($start)) === $start);
}

Please see this document: http://www.php.net/manual/en/language.types.string.php

It is possible to access and modify a character of a string using an index.

The String End is: $string[strlen($string)-1];
The String Start is: $string[0];

Hello, and thanks for your comment. That wasn't quite what I meant. I intended the functions to return a boolean, (as per my examples in the original request). Not "str_end()"  which would return the final character, but "str_ends()", i.e. "does this string end with that string".

For example:
    if (str_ends($filename, ".jpg")){ ...
or 
    if (str_begins($url, "https://")){ ...


I do realise these are relatively trivial, but given how common this kind of construction is, I think they'd be useful to lots of people as a convenience.
