Validate phone number in php

Question

I am making a phone number validator and all numbers should start with 168 and then followed by 9 digits 123456789.In total the phone number should only have 12 digits.

I have tried this

$phoneNumber = '168921500789';
    if( preg_match( "/^\168[0-9]{9}$/", $phoneNumber ) ){
  echo "Valid number";
} else {
  echo "Invalid number";
}

When i run the script,the number is not valid.How can i make the script take only 12 digits that must start with 168?.

I'm not sure about phone number validation. You can test wether it matches a pattern but this does not prevent from entering a wrong number anyways. — Daniel W., Aug 25 '14 at 12:28

Your RegEx is wrong, there's an useless backslash before the 1. Correct:

/^168[0-9]{9}$/

Full code:

$phoneNumber = '168921500789';
if( preg_match( "/^168[0-9]{9}$/", $phoneNumber ) ){
  echo "Valid number";
} else {
  echo "Invalid number";
}

You had to remove 1 slash:

$phoneNumber = '168921500789';
    if( preg_match( "/^168[0-9]{9}$/", $phoneNumber ) ){
  echo "Valid number";
} else {
  echo "Invalid number";
}

Be careful. It is not universal validator. It does not handle variants starting with `00` or `+` sign. – mikep Nov 23 '17 at 11:24
