Question

When the row['error'] is bigger than 35, the value isn’t present and the result of the function is 0. Where is the problem?

<?php
    if ($row['error'] == "")
    {
        $error = "0";
    }
    else
    {
        $error = $row['error'];
    }

    if ($row['error'] != "")
    {
       if (strlen($error) > 35)
       {
           $error = substr($row['error'],0,32) + "...";
       }
       else
       {
           $error = $row['error'];
       }
    }
?>

Change

$error = substr($row['error'],0,32) + "...";

to:

$error = substr($row['error'],0,32) . "...";

The concatenate operator in PHP isn’t a plus (+) sign; it’s a period (.) sign
