'en_EN':

basically the first part is the language and the second part the region:
'en_EN' - english, England
'en_US' - english, United States

You can lookup the language tags like 'en_EN' here:

see "ietf-language-tags"

It interesting to note that the expected behavior for this function may change according to your ICU version.

In ICU 4.4.2 (standard for Ubuntu 10.* with PHP 5.3.5)

    With locale 'en', input of 100,1 returns 1001

In ICU 4.8.1 (standard for Ubuntu 12.* with PHP 5.3.10)

    With locale 'en', input of 100,1 returns "false"

Be sure to note your ICU version in phpinfo() to be sure you will get the expected output.

to parse English use this format: 'en_EN' .  I had to guess.  I have no idea where you would find these codes.

<?php
echo "<pre>";
$fmt = numfmt_create( 'en_EN', NumberFormatter::DECIMAL );
$num = "1,234,567.891";
echo
numfmt_parse($fmt, $num)."\n";
echo
numfmt_parse($fmt, $num, NumberFormatter::TYPE_INT32)."\n";
echo
"</pre>";
?>

If this doesn't work well all I can say is it shouldn't work because it makes no sense that  you would repeat the code twice "en and EN" in one code.  Stuff that makes no sense is hard to guess.   I couldn't find a page that has these codes either.  I guess documentation is bound to be incomplete since it's so voluminous.  Documentation has a language and syntax unto itself yet there are no tutorials on understanding documentation.
