password_verify
(PHP 5 >= 5.5.0, PHP 7, PHP 8)
password_verify — Verifies that a password matches a hash
Description
$password, string $hash): boolVerifies that the given hash matches the given password. password_verify() is compatible with crypt(). Therefore, password hashes created by crypt() can be used with password_verify().
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.
This function is safe against timing attacks.
Parameters
-
password -
The user's password.
-
hash -
A hash created by password_hash().
Return Values
Returns true if the password and hash match, or false otherwise.
Examples
Example #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.';
}
?>
The above example will output:
Password is valid!
