udskifte tags fra mysql udtræk.

Fandt denne på: http://dk2.php.net/manual/en/ref.strings.php

<?php

function get_string_between($string, $start, $end){
    $string = " ".$string;
    $ini = strpos($string,$start);
    if ($ini == 0) return "";
    $ini += strlen($start);   
    $len = strpos($string,$end,$ini) - $ini;
    return substr($string,$ini,$len);
}

$string = "this [suxmp]custom[/suxmp] function is useless [suxmp]Yes it is![/suxmp]!!";
echo get_string_between($string,"[suxmp]","[/suxmp]");
// must return "custom";
?>

men den stopper efter første hit, og kunne være rart hvis den kunne tjekke op mod et array så den kunne lave tags som f.eks. i phpBB med [url][/url] osv osv.

har så fundet dette:

<?php
// The \\2 is an example of backreferencing. This tells pcre that
// it must match the second set of parentheses in the regular expression
// itself, which would be the ([\w]+) in this case. The extra backslash is
// required because the string is in double quotes.
$html = "<b>bold text</b><a href=howdy.html>click me</a>";
$html2 = "bold text[a href=howdy.html]click me[/a]";

//$html = htmlentities($html);

preg_match_all("/(<([\w]+)[^>]*>)(.*)(<\/\\2>)/", $html, $matches, PREG_SET_ORDER);

foreach ($matches as $val) {
    echo "matched: " . htmlentities($val[0]) . "<br>\n";
    echo "part 1: " . htmlentities($val[1]) . "<br>\n";
    echo "part 2: " . htmlentities($val[3]) . "<br>\n";
    echo "part 3: " . htmlentities($val[4]) . "<br>\n\n";
}
?>

hvordan skal den preg_match_all skal ud for at kigge efter [...] istedet for <...> ?

lukker og prøver reg.exp :)
