RegExp that looks for a string and only replaced part of it...

[Mark Hanford]

I'm after a regular expression that looks through a string for a
certain code, and then replaces part of that code with some markup:

So look in this string:
this text contains (T123) a code.

And become this string
this text contains (T<a href="?a=123">T123</a>) a code.

The main problem I'm having is that my regexp replaces the whole
match, including the T:

$pattern='(T[0-9]{3})';
$replace='<a href="?a=\1">\1</a>';

This results in a hyperlink "?a=T123" when I want ?a=123

Any suggestions?

Thanks,

Mark

(Did you really intend to double the T like that?)

$pattern='T([0-9]{3})';
$replace='T<a href="?a=\1">T\1</a>';
