title: Regex for (+918047093311) or (+918061914444 PIN 6251)
body: <p>I am trying to write a regex for extracting a +91XXXXXXXXXX or 0XXXXXXXXX from the string  (+918047093311) or (+918061914444 PIN 6251) or (08061914444 PIN 6251).</p>
  <p>I want to read inside the bracket and fetch the number with +91 or 0 followed by 10 digit starting only from 9,8,7 and 6.</p>
  <p>So far I was able to make this -&gt; <code>^([0]|\+91)?[6789]\d{9}$</code></p>
  <p>This is able to detect a number starting from +91 or 0 then 10 digit number starting from 6,7,8 or 9.</p>
  <p>Please help</p>
