str_replace

[wingfighter]

hallo zusammen,

ich bin gerade dabei mein erstes forum zu programmieren. ich lasse im inhalt alle tag entfernen... also keine html möglich.

was mache ich aber, um links herauszufiltern und sie auch als solche anzeigen zu lassen.
über die suchfunktion in diesem forum bin ich leider nicht fündig geworden. also, ich hoffe, jemand von euch erbarmt sich, mir zu helfen.

Schau dir mal Powie's-Forum an (http://www.powie.de) da findest du sowas !
