OPINIE UŻYTKOWNIKÓW
|
Mimo, że strony WWW tworzymy już 5 lat zawsze znajdziemy coś ciekawego. Świadczy o tym chociażby nasza aktówka, w której znajduje się kilkadziesiąt porad, z których często korzystamy. Otwarta forma poradnika, czyli możliwość podrzucania tematów oraz wspólny ich rozwój, to nieoceniona pomoc. Uważam, ze abonament roczny jest niewspółmiernie niski do jakości zaprezentowanych materiałów.

$pattern = preg_replace("/\|/", "\\|", quote_meta($pattern));
would probably be better written as:
$pattern = str_replace("|", "\\|", quote_meta($pattern));
This will more effecient (especially in tight loops) than using a regex pattern.

As this do not escapes |, you should be careful using a quotemeta'ed string as a valid regexp pattern. I ran into such a hole just now, and ended up using this code:
<?php
$pattern = preg_replace("/\|/", "\\|", quote_meta($pattern);
?>

function cleanersql ($text) {
return preg_replace('/([\W])/i',"\\\\\\1",$text);
}
//**
- note the escaped escape chars (\)
- add chars to preserve in this regex section: [\W*CHARS*]
- give addslashes() a try ;-)

This function escapes characters that have special meaning in regular expressions. preg_quote() <http://php.net/manual/en/function.preg-quote.php> has similar functionality, but is more powerful since it escapes more characters (including one user-specified character).

qutemeta() is note for quoting meta tags, but is for quoting characters which can be misunderstanded by php or a database.
