I am using Ubuntu 14.04 and I am using lamp. I had a more complex issue but I figured out what is causing the error and made a small php-mysql connection snippet. When the connection file is included into the php/html file the whole thing displays a blank page.
My connect.php code:
<?php
$db_host = "localhost";
$db_user = "root";
$db_pass = "";
$db_name = "ecalendar";
$conn = mysqli_connect($db_host,$db_user,$db_pass,$db_name);
if(mysqli_connect_errno(){
echo "Error".mysqli_connect_errno();
}
?>
and my web page with connection file included:
<?php
include "connect.php";
?>
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p>Testing</p>
<?php
$sql="SELECT * FROM events WHERE eventid=1";
$result = mysqli_query($sql);
?>
<ul>
<li><?php $row = mysqli_fetch_array($result);
echo $result;
?>
</li>
</body>
</html>
<?php
mysqli_close($conn);
?>
The following line in connect.php:
if(mysqli_connect_errno(){
Should be:
if(mysqli_connect_errno()){ // note the extra ')'
You were not properly enclosing your condition with ().
