Compare Nodejs generated bcrypt hash in PHP

Question

Just to know about bcrypt hash comparison in different platforms, that I have one brypt hash which is generated at Nodejs server, now I am moving to PHP, I want to know about is this possible to compare already created bcrypt hashes(generated in Nodejs) in PHP

Node JS Code:

function hash(password) {
  return new Promise(function(fulfill, reject) {
    bcrypt.hash(password, 8, function(err, hashedPassword) {
      if (err) {
        reject(err);
      } else {
        fulfill(hashedPassword);
      }
    });
  });
}

Input : simha

output: $2a$10$c/EwGsRkoV4XHmsOJYWZ6.LurbDUFW.eq83SI8eu5JaMOsr6PyLrm

Is it possible to generate the ouput hash using input simha in PHP

I am trying the below one, but it is generating different hash

password_hash($password, PASSWORD_BCRYPT) 
//output : $2y$10$CfihL9RipXW88JAVvlyFlegM5BAyD5xQmNutjm9KepeXUn5cAwIX2

You shouldn't expect them to match, at least by default. This is because for both functions, a random salt is chosen every time you hash a value.

The important thing is not that the hash outputs match, but that they still validate. So you could take the hashed output from node.js and use it with password_verify() in PHP for example, and it should validate.

Thanks a lot it's working. Just roaming around password_hash, now cleared the concept. Thanks
