Description:
------------
Can we have the extra features added to strtr() that are in the GNU strtr? They'd be really useful.
In particular, the ability to delete certain characters from the string [currently we must resort to str_replace, which gets ugly], and to squeeze repeated characters to a single one [requires preg_replace() at the moment]
This could be done by adding some predefined constants such as
STRTR_DELETE, STRTR_SQUEEZE_REPEATS
Reproduce code:
---------------
In GNU tr, we can do things like
echo "hello world" | tr -s "l"
#results in "helo world" (duplicate 'l' removed)
echo "hello world" | tr -d 'od' ('o' and 'd' removed)
#results in "hell wrl"
echo "hello world" | tr -s "wl" "zl" (translate AND squeeze)
#results in "helo zorld"
(Support for character classes might be nice too)
Thank you.

Well, deleting characters is already possible, e.g. strtr("hello world", ['o' => '', 'd' => '']) Squeezing is not, but you could write your own userland implementation. If you still feel this would be a good feature addition, please pursue the RFC process[1]. [1] <https://wiki.php.net/rfc/howto>
