I want to have phone number in working combination of ‘0’ followed by 10 digit mobile number (or) 0091 folllowed by 10 digit mobile number (or) +91 followed by 10 digit number.
1) 0 followed and +91 folowed numbers are working with following regex i also want 0091 followed number to be worked, my regex is:
“^([0]|(?:[0][0]|\\+)(91))([7-9]{1})([0-9]{9})$”;
Could you suggest me working a regex.
解决方案
The exact regex you seem to be going for (based on what you’ve tried so far) is:
^(?:0091|\\+91|0)[7-9][0-9]{9}$
Begins with 0, +91 or 0091
Followed by a 7-9
Followed by exactly 9 numbers
No capture groups
Must match entire input
As a general tip, to have worked this out yourself I’d advise using a site like RegExr or RegexPal
Set it to multi-line mode (so that ^ and $ match at the end of each line) then add 0091, +91 and 0 into the input box on separate lines – so you have something like this.
Then try to make a regex that matches just that part, in your case you needed something like
^0091|\+91|0$
Note: on RegExr you don’t have to escape backslashes (so when you use the regex in java you need to go through escaping them).
