之前工作正常我已經重置了我的數據庫並註冊了，我們向散列添加了隨機鹽，並且註冊腳本工作正常，我們可以使用相同的密碼創建帳戶和帳戶，並且他們擁有不同的哈希值，但我們的登錄腳本是壞了，沒有登錄用戶，說他們的密碼不正確。將哈希加入鹽後無法使登錄腳本生效;在
不知道爲什麼 - 我們花了最後2個小時試圖修復它。我們使用了PHP錯誤檢查器（https://phpcodechecker.com/），沒有錯。
我們正在運行舊版本的PHP（5.6）和MySQL，並且當前無法更改。

大量的代碼了新賬戶，新的哈希：減少對相關部分請 –
沒有你正在使用會停止SQL注入功能，你正在改變實際的密碼值與這些功能。 '用戶名'也是唯一的嗎？另外5.6支持'mysqli'，'pdo'和'password_hash' /'password_verify'。 – chris85
