PHP: 
$msg = preg_replace ("/\[code\]((.|\n)*?)\[\/code\]/e", 'highlight_string("\\1","1")', $msg);

Zoals je hierboven ziet, de [ p h p ] word vervangen door een bepaald stukje HTML met highlighte_string daarin. Ik wil graag weten hoe ik dat doe, want ik heb dus nu wel de code die goed word weergeven maar ik wil:
tekst tekst
----------------
code (highlited)
----------------


Alvast bedankt
 
Ik ben niet zo thuis in stringfuncties, maar kun je niet eerst checken of er in een string
PHP: 
 staat. Dat je dan al die streepjes print. Dan de string highlited zet tot [ / php ], dan weer streepjes print en verder gaat?

Hier staan de stringfuncties: [url]http://www.php.net/manual/nl/ref.strings.php[/url]
 
mocht ik toch het antwoord nog vinden dan hoor je het van me.

Maar hoe zit het hier in dit forum dan?? of is dat een hele somme vraag :d
 
Zo zit het hier:

PHP: 
<?
      if (floor($phpversionnum) < 4) {
        $searcharray = array(
          "/(\[)(list)(=)(['\"]?)([^\"']*)(\\4])(.*)(\[\/list)(((=)(\\4)([^\"']*)(\\4]))|(\]))/siU",

Oh wacht eens, nu heb ik ook het antwoord op m'n eigen vraag geloof ik :p
[edit]bij mij werkt het nogsteeds niet :/// naja ik ga eerst wel verder met een ander projectje :p[/edit]
 
Laatst bewerkt:
hij deed het half, maar stopte weer met de volgende foutmelding;

Warning: Unknown modifier 'c' in /usr/local/psa/home/vhosts/dutchwebmasters.net/httpdocs/site/artikelensysteem/read.php on line 49


en op dit regel staat


PHP: 
$code = preg_replace($searcharray, $replacearray, $msg);
 
PHP: 
$code = preg_replace ("/\[code\](.+?)\[\/code\]/is", '<b>\\1</b>', $msg);


werkt, hij doet het prima. Behalve; hij laat de <b> tags gewoon staan!
 
wat bedoel je aap?

Dit heb ik nu:

PHP: 
<? 

$msg = "$show->text";

 


// $msg = preg_replace("/\[code\](.+?)\[\/code\]/is",'<hr>\\1', $msg);
$msg = preg_replace("/\[b\](.+?)\[\/b\]/is",'<b>\\1</b>', $msg);   
$msg = preg_replace("/\[i\](.+?)\[\/i\]/is",'<i>\\1</i>', $msg);   
$msg = preg_replace("/\[u\](.+?)\[\/u\]/is",'<u>\\1</u>', $msg);  
$msg = preg_replace("/\[img\](.+?)\[\/img\]/is",'<img src="\\1">', $msg); 
$msg = preg_replace("/\[url\](.+?)\[\/url\]/is",'<a href=\"\\1\">\\1</a>', $msg); 
$msg = preg_replace('/\[code\]((.|\n)*?)\[\/code\]/is',"<hr>\\1<hr>", $msg);


                
highlight_string($msg);
$msg2 = str_replace("\n", "<br />", $msg);
echo "$msg2";
?>
De replace werkt, alleen zet hij nu alles in "tekst" zegmaar in het document. Hij zet dus (bijv:

< h r >hier de code die men heeft ingevult < h r >


Erg jammer

Erm, dat is toch ook de bedoeling? Er mag toch geen HTML gepost worden?
 
met wat hulp ben ik er EINDELIJK helemaal achter, het werkt nu helemaal;
