Php error on connecting to mysql database

Question

I wrote my code like this

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

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

but this is my error

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

Answer 1

You need commas to separate the parts in your connection:

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