PHP for loop not iterating fully inside HTML email

Question

I have a PHP script through which I send HTML emails. I'm using a 'for' loop to collect data and storing it in a variable. The loop is instructed to run 25 times. The problem is that it is looping only 19 times. I checked for any unlcosed tags or typos in syntax but didn't find any. I'm posting the for loop section in case any of you can spot what I couldn't. It is really frustrating as I think the solution is very simple and yet I'm unable to spot the problem.

My headers for the 'mail()' function are fine. Here they are just in case

$headers = "From: $from \r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

And here is my for loop:

$abc ="<table width='600'>";
        $abc .= "<tr>
                        <td bgcolor='#d6bf86'><span style='color:#9c2a00'>Number of Products</span></td>
                        <td align='center' bgcolor='#fde4d0'>$pagess</td>
                        <td align='center' bgcolor='#c3deb9'>$pagese</td>
                        <td align='center' bgcolor='#bee7f8'>$pagesu</td>
                    </tr>";


        for($i=1; $i<=25; $i++)
        {
            $abc .="<tr>";
            if($i % 2 == 0)     //  EVEN ROW
            {       
                    $abc .= "<td bgcolor='#d6bf86' width='260'><span style='color:#9c2a00'>".${f.$i}."</span></td>";
            }
            else                //  ODD ROW
            {
                    $abc .= "<td bgcolor='#fffbd0' width='260'><span style='color:#9c2a00'>".${f.$i}."</span></td>";
            }

                    if(isset(${s.$i}))      
                    {
                        $abc .= "<td bgcolor='#fde4d0' align='center'>Yes</td>";
                        ${s.$i} = "Yes";
                    }
                    else
                    {
                        $abc .= "<td bgcolor='#fde4d0' align='center'>No</td>";
                        ${s.$i} = "No";
                    }
                    if(isset(${e.$i}))
                    {
                        $abc .= "<td bgcolor='#c3deb9' align='center'>No</td>";
                        ${e.$i} = "Yes";
                    }
                    else
                    {
                        $abc .= "<td bgcolor='#c3deb9' align='center'>Yes</td>";
                        ${e.$i} = "No";
                    }
                    if(isset(${u.$i}))
                    {
                        $abc .= "<td bgcolor='#bee7f8' align='center'>No</td>";
                        ${u.$i} = "Yes";
                    }
                    else
                    {
                        $abc .= "<td bgcolor='#bee7f8' align='center'>Yes</td>";
                        ${u.$i} = "No";
                    }
            $abc .="</tr>";
        }


        if(isset($_POST['dscs']))   //  DISCOUNT HAS BEEN APPLIED
        {

            $abc .= "<tr>
                            <td>Base Price</td>
                            <td align='center'>$sums</td>
                            <td align='center'>$sume</td>
                            <td align='center'>$sumu</td>
                        </tr>";
            $abc .= "<tr>
                            <td>Discount Offered</td>
                            <td align='center'>$discount% </td>
                            <td align='center'>$discount% </td>
                            <td align='center'>$discount% </td>
                        </tr>";
            $abc .= "<tr>
                            <td>Effective Price</td>
                            <td align='center'>$dscs</td>
                            <td align='center'>$dsce</td>
                            <td align='center'>$dscu</td>
                      </tr>";
        }
        else
        {
            $dscs = $sums;
            $dsce = $sume;
            $dscu = $sumu;
            $abc .= "<tr>
                            <td>Total Price</td>
                            <td align='center'>$sums</td>
                            <td align='center'>$sume</td>
                            <td align='center'>$sumu</td>
                        </tr>";
        }

        $abc .="</table>";

I can attach the screenshot of the email that is being sent to give an idea on how the code is breaking. Let me know if you want the screenshot too.

PS : I copy-pasted this code in a separate file and ran it and it was working fine. The loop iterated 25 times. This makes me believe that there is a problem putting it inside HTML email.

Also adding in the email script if that helps:

$to = $clem;
$subject = "Something goes here";
$message = "<html>
<head></head>
<body style='background-color:#ffffff; font-family:Lucida Sans Unicode, Lucida Grande, sans-serif;'>
    <table width='600'>
        <tr>
            <td>$abc</td>
        </tr>
    </table>
</body>
</html>";

$from = "$logged_user";
$headers = "From: $from \r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$res=mail($to,$subject,$message,$headers);

Thanks in advance, Nisar

in for loop after $abc .="<tr>"; echo $i .. so that you can have exact idea that what is the value of $i when loop is completely executed. — Rukmi Patel

Ok Slayer. I'll do that right now and let you know in a minute. EDIT : It is showing 19. So the loop is breaking. — asprin

what is the value of i .. is that continuous from 1-19 or something else? — Rukmi Patel
– Rukmi Patel, Commented Apr 17, 2012 at 4:27
well I run your code in my system . loop runs continuously for 25. — Rukmi Patel

That is what I get too. When I echo $abc on submission of form, I see all 25 rows on the php page. But the same $abc is showing only 19 rows in the email. This makes me believe that something is messed up in the email script because $abc is working fine. — asprin

Nevermind, I found what was wrong. Here it is for people with similar problems.

I learnt that html emails have a 990 character limit per line. That was the reason why my code was breaking
