Validator.js: isMobilePhone - incorrect rule for pt-BR locale

[viniciushvsilva]

Describe the bug
The regexp in use is incorrect for mobile phones in Brazil, and it also has a few bugs as mentioned below:

Bugs

1. Second regexp group is useless as first group is always used
   The second group ( [6-9]{1}\d{3}\-?\d{4} ) is included in the first one ( \d{4}\-?\d{4} )

2. There is an OR operator missing between the first and second group

3. The two digits that precedes the phone number can be wrapped around parentheses, just like the first 3 digits of the en-US phone number, also it's possible to have a space between the country code and area code, and between the area code and phone number

Examples of phone numbers

With country code and area code

• [phone]
• [phone]

Without country code, with area code in parentheses

• (11) 97123-1234
• (11) 7123-1234

Without country code, with 0 followed by area code

• 015 97123-1234
• 015 7123-1234

Without country code, without 0, with area code

• 11 97123-1234
• 11 7123-1234

Suggested RegExp
I'd suggest the usage of the following regexp as it fixes above issues.

/^((\+?55\ ?[1-9]{2}\ ?)|(0[1-9]{2}\ ?)|(\([1-9]{2}\)\ ?)|([1-9]{2}\ ?))((\d{4}\-?\d{4})|(9[6-9]{1}\d{3}\-?\d{4}))$/

Hello my friends I'm having trouble sending to cell phones that the second number of cell 4, for example 11945555555, here in São Paulo / Brazil some phones are like this
Suggest :
/(?=^(+?5{2}-?|0)[1-9]{2}-?\d{4}-?\d{4}$)(^(+?5{2}-?|0)[1-9]{2}-?[6-9]{1}\d{3}-?\d{4}$)|(^(+?5{2}-?|0)[1-9]{2}-?9[4-9]{1}\d{3}-?\d{4}$)/

@lacort Agreed, I was about to publish this but I realised that some numbers in São Paulo might start with 9 and be followed by a 4 (and apparently 3 too), it seems that those are new numbers given by certain ISP companies (like Vivo and Nextel) in São Paulo state (but mainly in São Paulo city). I should have a look at this by the end of the day.

If anybody wants to tackle this as a PR, I would be most appreciative as it is beyond my immediate knowledge.

Opened a new PR, with changes I made. It should now support new phone numbers that start with 9 and be followed by 2, 3, 4 and 5 too.
