How to Explode String Right to Left?

You may use strrev to reverse the string, and then reverse the results back:

$split_point = ' - ';
$string = 'this is my - string - and more';

$result = array_map('strrev', explode($split_point, strrev($string)));

Not sure if this is the best solution though.

How about this:

$parts = explode($split_point, $string);
$last = array_pop($parts);
$item = array(implode($split_point, $parts), $last);

Not going to win any golf awards, but it shows intent and works well, I think.

Here is another way of doing it:

$split_point = ' - ';
$string = 'this is my - string - and more';

$stringpos = strrpos($string, $split_point, -1);
$finalstr = substr($string,0,$stringpos);
