<div class="contentfont" style="padding-left:20px; text-align:left;">
<?php 

$words = explode(" ",$dcontent);
$cntWords = count($words); 
$splitWords = round($cntWords/2);

for ($i=0;$i<=$splitWords;$i++)
{
print $words[$i].' ';
$halfPoint = $i;
}
?>

<p class="contentfont" style="padding-top:10px;">
<?php 
for ($i=$halfPoint;$i<=$cntWords;$i++) 
{
print $words[$i].' ';// This print statement is causing me this error     Notice: Undefined offset: 41 in D:\xampp\htdocs\training\admin-panel\php\sai_devotees_detail.php on line 106
}
?>
</p>

Undefined offset in this case means you are reading past the length of the $words array. Try $cntWords - 1 for ceiling of the loop like this:

for ($i = $halfway; $i <= $cntWords -1; $i++) {

$halfPoint = $i; is also outside the loop. Try this instead:

for ($i = 0; $i <= $splitWords; $i++) {
    print $words[$i] . ' ';
    $halfPoint = $i;
}

When you make a loop in PHP without brackets, only the first statement after it will be executed. So in this case, $i doesn't exist for you to assign it to $halfPoint. Don't think it's clever to compact everything into one line. It will only cause you problems.
