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>"; }

Facebook Meta Tag - og:description for database value with strip_tags() and substr() $descpp = substr($fetchForumData[0]['descp'], 0, 300)."..."; // echo $descrp {As it shows correctly as the description data from database limit to 300 words via echo} <meta property="og:description" content="<?php echo strip_tags($descpp); ?>" /> The following script not working and shows result on facebook as '....' rather than '$descpp + .....' And I already debug via http://developers.facebook.com/tools/debug also. And for <meta property="og:description" content="<?php echo $fetchForumData[0]['descp']; ?>" />... its shows complete content on the top of the article page and after comment via facebook comment plugin it shows blank space on facebook timeline. What is missing? Kindly advice as soon as possible.
