Converting a Javascript regular expression to preg_match() compatible

I have this code from a javascript

/+\uFF0B0-9\uFF10-\uFF19\u0660-\u0669\u06F0-\u06F9u/

after some read about php & \u support I convert it to \x

/\+\x{FF0B}0-9\x{FF10}-\x{FF19}\x{0660}-\x{0669}\x{06F0}-\x{06F9}/u

but still I'm not able to use it in php

$phoneNumber = '+911561110304';
$start = preg_match('/\+\x{FF0B}0-9\x{FF10}-\x{FF19}\x{0660}-\x{0669}\x{06F0}-\x{06F9}/u', $phoneNumber,$matches);

the matches will be null!

how to fix this?

It looks like you want to match an ASCII plus sign or its Japanese Halfwidth equivalent, followed by one or more digits from a few different writing systems. But, as @mario observed, you seem to be missing some square brackets. The JavaScript version probably should be:

/[+\uFF0B][0-9\uFF10-\uFF19\u0660-\u0669\u06F0-\u06F9]+/

(I couldn't see any reason for the u at the end, so I dropped it.) The PHP version would be:

'/[+\x{FF0B}][0-9\x{FF10}-\x{FF19}\x{0660}-\x{0669}\x{06F0}-\x{06F9}]+/u'

Of course, this will allow a mix of ASCII, Arabic and Halfwidth characters in the same number. If that's a problem, you'll need to break it up a bit. For example:

'/\+(?:[0-9]+|[\x{0660}-\x{0669}]+|[\x{06F0}-\x{06F9}]+)|\x{FF0B}[\x{FF10}-\x{FF19}]+/u'
