PHP的错误

Question

我写了我这样的代码

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

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

但是这是我的错误

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

Answer 1

您需要逗号的部分在连接分离：

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