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.

'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:
