PHP - Is There A Way To Trim Everything In Front Of The Last Backslash?

The issue I'm having is when the returned data has data to place inside of fields it does but when there isn't data then it shows a backslash and I'm not sure why? Any ideas?

Code: [Select]
<form action="#" id="bioForm" >
        <?php 
        while ($row = mysqli_fetch_array($groupsResult, MYSQLI_ASSOC)) {
            echo "<fieldset>
            <legend>" . $row['groupName'] . "</legend>";
            $fieldsResult = mysqli_query ( $dbc, sprintf($fieldsQuery,$row['ID']) );
            echo $fieldsQuery;
            while ($row2 = mysqli_fetch_array($fieldsResult, MYSQLI_ASSOC)) {
                echo "<div class=field required>";
                if ($row2['inputType'] == "text") {
                    echo "<label for=" . $row2['ID'] . ">" . $row2['fullName'] . "</label>";
                    echo "<input type=text name=" . $row2['ID'] . " id=" . $row2['ID'] . " class=text biofield title=" . $row2['fullName'] . " value=" . $row2['content'] . " />";     
                } elseif ($row2['inputType'] == "textarea") {
                    echo "<label for=" . $row2['ID'] . ">" . $row2['fullName'] . "</label>";
                    echo "<textarea name=" . $row2['ID'] . " id=" . $row2['ID'] . " class=textarea biofield title=" . $row2['fullName'] . " >" . $row2['content'] . "</textarea>";
                } else {
                    echo "<label for=" . $row2['ID'] . ">" . $row2['fullName'] . "</label>";
                    echo "<select name=" . $row2['ID'] . " id=" . $row2['ID'] . " class=dropdown biofield title=" . $row2['fullName'] . " >";
                    echo "<option value= >None</option>";
                    if ($styleID == 1 || $styleID == 2 || $styleID == 6) {

                        SELECT 
                            characters.ID, 
                            characters.characterName 
                        FROM 
                            characters 
                        WHERE 
                            characters.styleID IN (1,2,6)
                        ORDER BY 
                            characters.characterName";
                    }
                    
                    $charactersResult = mysqli_query ( $dbc, $charactersQuery ); // Run The Query
                    
                    while ( $manager_row = mysqli_fetch_array ( $charactersResult, MYSQL_ASSOC ) ) {

              print " SELECTED";
         }
                            print ">".$manager_row['characterName']."</option>\r";
                    }
                    
                    echo "</select>";
                }
                
                echo "</div>";
            }
            echo "</fieldset>";
        } 
        ?>

            <input type="hidden" name="defaultCharID" id="defaultCharID" value="<?php echo $defaultCharID; ?>" />
            <input type="submit" class="submit" id="editBio" title="Edit Bio" value="Edit Bio" />
        </fieldset>

Code: [Select]

For a very 'loose' email address validator, does the following regex need the backslash before the dot?   ^\S+@\S+\.\S+$   (Checks for anything@anything.anything but I'm gonna change that to anything.anything to make it even 'looser')   I tested with and without the backslash using rubular.com and it seems superfluous but I'd like a second opinion or two please.   ALSO: does rubular.com use the right engine to be correct for php? I hope so coz it's the first time I've been able to fully understand some regexes I've been blindly implementing for some time!     Many thanks in advance

What is the correct way to use the backslash here?  I am using an ftp script and retrieving the brand directory name through url.  I want to catch it if they try to use \ in the url to list all directories.

Code: [Select]
elseif($_GET[f]=="\")
{
echo "You have entered an invalid vendor.";

$_SESSION['brand_path'] = "INVALID";
}

I am working on taking out the Deprecated functions from my site so while replacing ereg with preg_match I get the below error. Per a message I found on the internet it says to replace ereg with preg_match and everything should work. Can anyone assist me with fixing this error?

Error: Warning: preg_match() [function.preg-match]: Delimiter must not be alphanumeric or backslash

Part where error is contained

if (preg_match('enum.(.*).', $row['Type'], $match)) {
    $opts = explode(',', $match[1]);
    foreach ($opts as $item)
        $finalResult[] = substr($item, 1, strlen($item)-2);
}


Full Function

function getEnumOptions($table, $field) {
   global $db;
   
   $finalResult = array();

   if (strlen(trim($table)) < 1)
    return false;
   
   $query  = "show columns from " . $db['tickets_slave']->escapeSimple($table);
   $res =& $db['tickets']->query($query);
   if (PEAR::isError($res)) {
throw new TixException($_SERVER['SCRIPT_NAME'] . ":", TixExceptionCodes::UNKNOWN_ERROR);
   } else {
try {
while ($res->fetchInto($row)) {
        if ($field != $row["Field"]) {
        
       } else {         
        //check if enum type
        if (preg_match('enum.(.*).', $row['Type'], $match)) {
            $opts = explode(',', $match[1]);
            foreach ($opts as $item)
                $finalResult[] = substr($item, 1, strlen($item)-2);
        }
       }
}
} catch (TixException $ex) {
throw new TixException($_SERVER['SCRIPT_NAME'] . ":", TixExceptionCodes::UNKNOWN_ERROR);
}
   }
   return $finalResult;
}

Hello,

I have been messing around with this and can't seem to figure out what I'm doing wrong.  I'm pretty new to php, so it might be something silly.

Original code:
Code: [Select]
$a1=mysql_result($result,$i,"question"); //Question
$a2=mysql_result($result,$i,"answer"); //Answer
$a3=mysql_result($result,$i,"submission_id"); //submission id
$a4=mysql_result($result,$i,"category"); //submission id

echo "<a name=\"$a3\"></a><strong>$a1</strong>$a2";

Prints:

Question

Category

What I want is:

Question
Category

I have tried using the trim functions but nothing seems to help:

Code: [Select]
$a1=mysql_result($result,$i,"question"); //Question
$a2=mysql_result($result,$i,"answer"); //Answer
$a3=mysql_result($result,$i,"submission_id"); //submission id
$a4=mysql_result($result,$i,"category"); //submission id
$a1 = rtrim($a1);
$a2 = ltrim($a2);

echo "<a name=\"$a3\"></a><strong>$a1</strong>$a2";
Ideas?
