Just wondering if anyone can help me preg_match a Stellar public address in PHP?

1 Answer 1


A stellar address begins with "G", followed by "[A-D]" and then 54 characters from this base32 alphabet "[ABCDEFGHIJKLMNOPQRSTUVWXYZ234567]", so:

preg_match('/^G[ABCD]{1}[ABCDEFGHIJKLMNOPQRSTUVWXYZ234567]{54}$/', $s);

However you could also use this php sdk like this:

  try {
        $key = \ZuluCrypto\StellarSdk\Keypair::newFromPublicKey($s);
   } catch (Exception $e) {
        exit('Invalid Address: ' . $s);
