Validate Mobile number using regular expression

I need to validate mobile number. My need:

The number may start with +8801 or 8801 or 01

The next number can be 1 or 5 or 6 or 7 or 8 or 9

Then there have exact 8 digit.

How can i write the regular expression using this conditions ?

After trying (^(?:+?88)?01[13-9]\d{8}$), my program shows the correct

8801100001111

The number may start with +8801 or 8801 or 01.(I want only 8801).

The next number can be 3 or 4 or 5 or 6 or 7 or 8 or 9 which are valid number in the position for Bangladesh.

Then there have exact 8 digit.

my solution ==> ^8801[3-9]\d{8}$

Regular expression of Bangladeshi phone numbers(what i want) where number of characters=13 , start with 8801, the 5th character can be 3 to 9 not 0, 1, 2, and the other 8 characters can be 0 to 9.

Should be pretty simple:

^(?:\+?88)?01[15-9]\d{8}$

^ - From start of the string
(?:\+?88)? - optional 88, which may begin in +
01 - mandatory 01
[15-9] - "1 or 5 or 6 or 7 or 8 or 9"
\d{8} - 8 digits
$ - end of the string

Working example: http://rubular.com/r/BvnSXDOYF8

Update 2020

As BTRC approved 2 new prefixes, 013 for Grameenphone and 014 for Banglalink, updated expression for now:

^(?:\+?88)?01[13-9]\d{8}$

Bangladeshi phone number (Citycell, Robi, Grameen Phone, Banglalink, Airtel and Teletalk operators) validation by using regular expression :

$pattern = '/(^(\+8801|8801|01|008801))[1-9]{1}(\d){8}$/';
$BangladeshiPhoneNo = "+8801840001417";

if(preg_match($pattern, $BangladeshiPhoneNo)){
    echo "It is a valid Bangladeshi phone number;
}

I know, that question was asked long time ago, but i assume that @G. M. Nazmul Hossain want to validate mobile number againt chosen country. I show you, how to do it with free library libphonenumber from Google. It's available for Java, C++ and Javascript, but there're also fork for PHP and, i believe, other languages.

+880 tells me that it's country code for Bangladesh. Let's try to validate example numbers with following code in Javascript:

String bdNumberStr = "8801711419556"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    //BD is default country code for Bangladesh (used for number without 880 at the begginning)
    PhoneNumber bdNumberProto = phoneUtil.parse(bdNumberStr, "BD");
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}
boolean isValid = phoneUtil.isValidNumber(bdNumberProto); // returns true

That code will handle also numbers with spaces in it (for example "880 17 11 41 95 56"), or even with 00880 at the beggininng (+ is sometimes replaced with 00).

Try it out yourself on demo page. Validates all of provided examples and even more.
