It\'s very easy..

<?php
include_once($_SERVER[\'DOCUMENT_ROOT\'].\'/wp-includes/class-phpass.php\' );

// prepare database connection
$ip_address="localhost";
$user_db="userdb";
$pass_db="passdb";

$conn= mysql_connect($ip_address,$user_db,$pass_db);
mysql_select_db("dbname",$conn);
if (!$conn){
            echo "Could not connect: " . mysql_error();
            exit();
}

// wordpress\' username that his password going to compare
$user = \'test\';
$user_name = htmlspecialchars($user,ENT_QUOTES);

// plain password to compare
$password = \'tespass\';

$hasher = new PasswordHash(8, TRUE);

// get user_name\'s hashed password from wordpress database
$queryx = "select * from wa1gty5f_users where user_login=\'$user_name\'";
$Resultx = mysql_query($queryx,$conn);

while($row = mysql_fetch_array($Resultx)){
     $passnya = $row[user_pass];
}

// compare plain password with hashed password
if ($hasher->CheckPassword( $password, $passnya )){
    echo "MATCHED";
} else {
    echo "NO MATCHED";
}
?>

我遇到了这个问题，并在wp_hash_password()

将已哈希的密码与其纯文本字符串进行比较

<?php

$wp_hasher = new PasswordHash(8, TRUE);

$password_hashed = \'$P$B55D6LjfHDkINU5wF.v2BuuzO0/XPk/\';
$plain_password = \'test\';

if($wp_hasher->CheckPassword($plain_password, $password_hashed)) {
    echo "YES, Matched";
} else {
    echo "No, Wrong Password";
}

?>

最后，大约10年后。找到了确切的答案，问题是什么。

您想使用核心PHP来实现这一点，对吗？这是你的密码！首先，您需要添加一个类：->；只需从wp-includes/class-phpass.php-&燃气轮机；别担心。它是用核心PHP编写的。
