[SOLVED] why doesn't this simple regex match?

[dsaba]

<?php
$str = '" \\an//d " " \\an//d "';
echo "$str<br>";
$pat = '~(" )(\\an//d)( ")~e';
preg_match_all($pat, $str, $out);
print_r($out);
?>

 

outputs:

" \an//d " " \an//d "<br>
Array
(
    [0] => Array
        (
        )

    [1] => Array
        (
        )

    [2] => Array
        (
        )

    [3] => Array
        (
        )

)

 

Why doesn't it match? (read it carefully)

ah here is why I changed this:

$pat = '~(" )(\\an//d)( ")~e';

 

to this:

$pat = '~(" )(\\\an//d)( ")~e';

 

you have to escape for the pattern itself, and then again for the string declaration
