PHP using xampp Parse error: syntax error, unexpected '$query' (T_VARIABLE) [duplicate]

Question

For some reason it is giving me this error Parse error: syntax error, unexpected '$query' (T_VARIABLE)
code:

$query="SELECT * FROM posts, users 
WHERE posts.userID = users.userID ORDER BY postTimestamp";          
$result = mysqli_query($connection $query); 

Answer 1

You forget to use the ',' in $result

$result = mysqli_query($connection, $query);

Answer 2

The reason is comma that you have forgotten:

$query="SELECT * FROM posts, users 
WHERE posts.userID = users.userID ORDER BY postTimestamp";          
$result = mysqli_query($connection, $query);
