[SOLVED] Leading Zero?

$conn = mysql_connect("localhost", "root", "")
or die(mysql_error());
$db = mysql_select_db("smrpg", $conn) or die(mysql_error());

//create and issue query
$sql = "insert into access_tracker values
('', '$page_title', '$user_agent', '$date_accessed')";
mysql_query($sql,$conn);
?>

I wanted to add a leading zero if the $num_knights is less than 10, but I can't get the code to work. Here is what I tried:

 

//create the display string
$display_block .= "<table cellpadding=3 cellspacing=3 border=1>
<tr>
<th>KNIGHTS</th>";
if ($num_knights<10){

         $num_knights = "0"+$num_knights;

      }
display_block .= "<th># OF PLAYERS: $num_knights</th>
</tr>";

 

But that didn't work. How do I do this?

[kratsg]

JavaScript uses the "+" format for concatenating strings. PHP uses the "." format.

 

<?php
//create the display string
   $display_block .= "<table cellpadding=3 cellspacing=3 border=1>
   <tr>
   <th>KNIGHTS</th>";
if ($num_knights<10){

         $num_knights = "0".$num_knights;

      }
   display_block .= "<th># OF PLAYERS: $num_knights</th>
   </tr>";
?>

I'm getting:

 

Parse error: parse error in C:\wamp\www\listcharacters.php on line 93

 

Here's what I changed:

 

$display_block .= "<table cellpadding=3 cellspacing=3 border=1>
<tr>
<th>KNIGHTS</th>";
if ($num_knights<10){

         $num_knights = "0".$num_knights;

      }
  display_block .= "
<th># OF PLAYERS: $num_knights</th>
</tr>";

 

What am I doing wrong?

[twilitegxa]

Nevermind I see if. I forgot the $.

[timmah1]

Could be your missing a $ on line10

<php
$display_block .= "<table cellpadding=3 cellspacing=3 border=1>
   <tr>
   <th>KNIGHTS</th>";
   if ($num_knights<10){

         $num_knights = "0".$num_knights;

      }
     $display_block .= "
   <th># OF PLAYERS: $num_knights</th>
   </tr>";
?>

 

this works for me

<?php
$num_knights = 9;
$display_block .= "<table cellpadding=3 cellspacing=3 border=1>
   <tr>
   <th>KNIGHTS</th>";
   if ($num_knights<10){

         $num_knights = "0".$num_knights;

      }
     $display_block .= "
   <th># OF PLAYERS: $num_knights</th>
   </tr></table>";
  echo $display_block;
?>
