How can I use regex to validate phone numbers?
You can use a regex pattern like ^+?[1-9]\d{1,14}$ to validate international phone numbers.
What does this regex pattern mean?
The pattern checks for an optional '+' sign, followed by a digit between 1-9, and then up to 14 more digits.
Can you give me an example of a valid phone number?
Sure! A valid phone number could be +12345678901234 or 1234567890.
What about invalid phone numbers?
Invalid examples include 12345 (too short) or +123abc456 (contains letters).
