# password_verify

(PHP 5 >= 5.5.0)

password_verify — Verifies that a password matches a hash

### Beschreibung

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

Verifies that the given hash matches the given password.

Note that password_hash() 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.

### Parameter-Liste

`password`

  The user's password.

`hash`

  A hash created by password_hash().

### Rückgabewerte

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

### Beispiele

Beispiel #1 password_verify() 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.';
}
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    Password is valid!
