PHP mysqli_fetch_array获得一般致命错误

Question

I have to use a php function to manage some data from a db, but i get a Fatal Error on the line where I call mysqli_fetch_array().

    $request = "SELECT Post.* FROM Post WHERE IdUseFk = '".$user_idPk."';";
    $result  = mysqli_query($CONN, $request)
        or die ("<font color='red'>Error: ".mysqli_error($CONN)."</font>");
    $num = mysqli_num_rows($result);

    if ($num == 0) {echo "NOTHING TO DO HERE";}
    else
    {    
        for ($i=1; $i<=$num; $i++)
        {
            $row = mysqli_fetch_array($result, MYSQLI_ASSOC);  //<<-- ERROR ON THIS LINE

            /*...Some other code...*/
        }

    } 

I get this: Fatal error: in C:\\xampp\\htdocs\\Work\\load_data.php on line 137

Any suggestion?

EDIT: PROBLEM SOLVED

I can't believe it. For some reason the 'space' chars I put before and after the '=' char in $row = mysqli_fetch_array()

weren't real spaces but another special char that is blank in most editors but php read as part of the function name. I was able to see it thanks to the editor in cpanel. Now it works

Try using a while loop, and you also had an error in your SQL syntax.

$request = "SELECT Post.* FROM Post WHERE IdUseFk = '$user_idPk'";
$result = mysqli_query($CONN, $request)
     or die ("<font color='red'>Error: ".mysqli_error($CONN)."</font>");
$num = mysqli_num_rows($result);

    if ($num == 0) { 
        echo "NOTHING TO DO HERE";
    }  else {    
        while($row = mysqli_fetch_array($result) {
           /*...Some other code...*/     
        }
    }
