PASSWORD_VERIFY(3)							 1							PASSWORD_VERIFY(3)

password_verify - Verifies that a password matches a hash

SYNOPSIS
       boolean password_verify (string	$password, string  $hash)

DESCRIPTION
	Verifies that the given hash matches the given password.

	Note  that password_hash(3) returns the algorithm, cost and salt as part of the returned hash. Therefore, all information that's needed to
       verify the hash is included in it. This allows the verify function to verify the hash without needing separate  storage	for  the  salt	or
       algorithm information.

PARAMETERS
	      o $password
		- The user's password.

	      o $hash
		- A hash created by password_hash(3).

RETURN VALUES
	Returns TRUE if the password and hash match, or FALSE otherwise.

EXAMPLES
       Example #1

	      password_verify(3) example

	      <?php
	      // See the password_hash() example to see where this came from.
	      $hash = '$2y$07$BCryptRequires22Chrcte/VlQH0piJtjXl.0t1XkA8pw9dMXTpOq';

	      if (password_verify('rasmuslerdorf', $hash)) {
		  echo 'Password is valid!';
	      } else {
		  echo 'Invalid password.';
	      }
	      ?>

	      The above example will output:

	      Password is valid!
