PHP的錯誤

Question

我寫了我這樣的代碼

<?php 
    $dbCon = mysqli_connect("localhost" "XXXXXXXX" "XXXXXXXXX"); 

    if(mysqli_errno()){ 
     echo "Cannot connect:" .mysqli_connect_error(); 
    } 
?> 

但是這是我的錯誤

Parse error: syntax error, unexpected '"XXXXXXXX"' (T_CONSTANT_ENCAPSED_STRING) in C:\xampp\htdocs\Project\connection.php on line 2

您需要逗號的部分在連接分離：

$dbCon = mysqli_connect("localhost", "XXXXXXXX", "XXXXXXXXX");
