Hello, A not so experienced PHP-user here. For my school assignment, I have to make the following: "Stolwijkstraat 8" has to be shortened into SW with use of SUBSTR and STRTOUPPER. My question: 1. How can I be able to use SUBSTR and STRTOUPPER in the same line? 2. How can I be able to remove everything in the line ''Stolwijkstraat 8", on behalf of ''S'' and ''w''? A quick response would be greatly appreciated. Kind regards.

Hello all, I have created a script that queries my MySQL database and gets a certain row, then echoes out: if(!$result = $db->query($sql)){ die('There was an error running the query [' . $db->error . ']'); } while($row = mysqli_fetch_array($result)) { echo "<li><a href=\"#\">"; echo $row['col_5']; echo "</li>"; } I would like to check to see if each of the row outputs has a string that is more than 13 characters, and if so, strip it down to 13 and add "..." to the end of the string. I did some research and added a line of code, but it still outputs the long string. Any ideas on where I went wrong? if(!$result = $db->query($sql)){ die('There was an error running the query [' . $db->error . ']'); } while($row = mysqli_fetch_array($result)) { $row = (strlen($row) > 13) ? substr($row,0,10).'...' : $row; // ADDED THIS LINE echo "<li><a href=\"#\">"; echo $row['col_5']; echo "</li>"; }
