Bug description:character @ not handled properly with \b
Description:
------------
Hi,
I have a problem with the @ character at the end of a word, with the word
delimiter \b:
input: i wrote this exampl@ for you
preg_match('/\bexampl@/','i wrote this exampl@ for you') = 1
preg_match('/\bexampl@\b/','i wrote this exampl@ for you') = 0
the second preg_match should also return 1 !!
Test script:
---------------
<?php
$input='i wrote this exampl@ for you';
echo "input: ".$input."\n";
$patt='/\bexampl@/';
echo "preg_match('".$patt."','".$input."') = ".preg_match($patt,
$input)."\n";
$patt='/\bexampl@\b/';
echo "preg_match('".$patt."','".$input."') = ".preg_match($patt,
$input)."\n";
?>
Expected result:
----------------
for both preg_match, output should be 1, that is, the pattern should be
found in the input string
preg_match('/\bexampl@/','i wrote this exampl@ for you') = 1
preg_match('/\bexampl@\b/','i wrote this exampl@ for you') = 1
Actual result:
--------------
preg_match('/\bexampl@/','i wrote this exampl@ for you') = 1
preg_match('/\bexampl@\b/','i wrote this exampl@ for you') = 0
