In the following code why the PHP preg_match returns false? note: I have read some older questions with the same title as my question but the context was different
<html>

<body>
<?php
$str = "This is a test for PCRE.";
$ptrn = "This";
$preg_match_result_arr;
$preg_match_result = preg_match($ptrn, $str, $preg_match_result_arr);
if (1 === $preg_match_result)
{
echo "The pattern has matched in the string:<br/>".
"the match is $preg_match_result_arr[0]<br/>";
}
elseif (0 === $preg_match_result)
{
echo "The pattern has not matched in the string:<br/>";
}
elseif (false === $preg_match_result)
{
echo "An error has occured in matching<br/>";
}
?>
</body>
</html>

Your expression is not correct, it should be surrounded by delimiters like so.
$ptrn = '/This/';
