Okay, thanks for pointing that out.
How do we place multiple Replacements in the $replacement argument to preg_replace? I've added
a double capture on my regular expression. If it is matched then I replace the the matched pattern
by prefix a single character the the value of ${1} from the captured pattern. I have found out that
I may need a second expression to capture all of the items in the file
<snip>
$aStr = array();
$aPat = array();
$aSum = array();
$aStr[] = "1. This is my first Qna";
$aStr[] = " 1. This is my first Qna";
$aStr[] = "11. This is my first Qna";
$aPat[] = "/(^\d{1,2}\.)|(^\s\d{1,2}\.)/";
$aPat[] = "/(^\d{1,2}\.)|(^\s\d{1,2}\.)/";
$aPat[] = "/(^\d{1,2}\.)|(^\s\d{1,2}\.)/";
****problem is here
$rep = "Q\${1}, ${2}";
$aSum = preg_replace($aPat, $rep, $aStr);
echo "<P>";
foreach( $aSum as $s )
{
echo "string = $s <BR>";
}

Enclose a capturing group (\d) and the use prefix\${1} inside the
replacement.
Check out the PHP manual:
$string = "April 15, 2003";
$pattern = "/(\w+) (\d+), (\d+)/i";
$replacement = "\${1}1,\$3";

I have a regular expression, that finds what i want. The problem lies in
that I don't want to replace this pattern with another. I want to prefix
the pattern with a character. Any suggestions as to how I might accomplish
this?
regular expression = '/^\d\{1,2}\./'
