Answer 1

In my code below substr function is not working, why it is so?

• Its because its been treated as string literal and not a function

How to make it work?

• You need to take care about string concatenation or simply store the value of substr within a variable.

Example:

$substr_value = substr($row['body'],0,300);
echo "
<h2>{$row['title']}</h2>
<p>$substr_value</p>
<p>{$row['posted']}</p>";
