如何更改mysql用戶密碼？

Question

嗨我更改mysql用戶密碼使用波紋管腳本但密碼不會更改。

$conn = mysqli_connect('host', 'root', 'password'); 
$dbUser = "username"; # same username as in your example 
$dbPass = "new_password"; # new password 

$queries = array(
    "USE mysql;", # switch to the 'mysql' database 
    "SET PASSWORD FOR '$dbUser'@'localhost' = PASSWORD('$dbPass');" 
); 

foreach($queries as $query) { 
    $rs = mysqli_query($conn, $query);   
} 

使用此腳本密碼不會更改，也不會顯示錯誤。

Answer 1

嘗試此查詢可能這將幫助你

mysql_query("UPDATE mysql.user SET Password = PASSWORD('$password') WHERE User='$username'"); 

Answer 2

剛剛嘗試此查詢

SET PASSWORD FOR 'bob'@'%.example.org' = PASSWORD('cleartext password'); 

Answer 3

試試這個，這也可以幫助SQL注入。

$query = sprintf("UPDATE mysql.user SET Password = '%s' WHERE User='%s'",mysqli_real_escape_string($dbPass),mysql_real_escape_string($dbUser)); 
$result = mysqli_query($query); 
if($result){ 
    echo "change success"; 
}
