Password Hashing 函数
PHP Manual

password_verify

(PHP 5 >= 5.5.0, PHP 7)

password_verifyVerifies that a password matches a hash

说明

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.

This function is safe against timing attacks.

参数

password

用户的密码。

hash

一个由 password_hash() 创建的散列值。

返回值

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

范例

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.';
}
?>

以上例程会输出:
