 ?>

i want to appear $total variable number in the link.why is this script not working?

Enclose the whole string with double quotes to embed variables inside:

echo "<div class=\"idsdiv\"><a href=\"profile.php?id=$total\">$total</a><div>";

You need to use double quotes around your HTML and single quotes around your attributes or do this...

echo '<div class="idsdiv"><a href="profile.php?id=' . $total .'">' . $total . '</a><div>  ';

PHP doesn't process variable names in strings enclosed in single quotes.

<?php
 $total=3;
 echo '<div class="idsdiv"><a href="profile.php?id=',$total,'">',$total,'</a><div>';
 ?>

Look at the string section of php.net (http://php.net/string) they talk about how to use each of the types. One of quote being the ' where nothing is parsed.

<?php  $total=3;  
echo "<div class=\"idsdiv\"><a href=\"profile.php?id=$total\">$total</a><div> ";  

?> 

you had errors with your quotes

You can print HTML without printing it, like so:

<?php
  $total = 3;
?>

<div class="idsdiv"><a href="profile.php?id=<?php echo $total; ?>"><?php echo $total; ?></a></div>

When I still did PHP, I found it much easier to manage than escaping tons of quotes and things like that.

You can even do it inside of an if block too:

<?php
  if ($foo == 'bar') {
?>

  <div>Foo is bar</div>

<?php
  }
?>

The method I like is

<?php  
     $total=3;  
     echo "<div class='idsdiv'><a href='profile.php?id={$total}'>{$total}</a><div>";  
?>

It is my method, but there are plenty of ways to do it. Maybe even too many. If you want more information you can always refer to the documentation.

<?php
  $total=3;
  echo '<div class="idsdiv"><a href="profile.php?id=$total">'.$total.'</a><div>';
?>

You're quote are missing before and after the $total
