preg_replace_callback

Hello. I have totally no clue at all wether I am posting in the right newsgroup here, and I was not planning on caching all messages in my (first time used, I prefer Outlook) Outlook Express before searching. So if I am disobeying all rules here ... I'm sorry ... I just am not an experienced news-service user ... Now, my question/remark/bug report. It concerns, ad you could guess, the preg_replace_callback function. The manual is very short on this function, and the comments posted on the online-version of the manual, are not helping me, either ... I am trying to use this function as the regular preg_replace can be used, namely woth a patterns-array, a replacement-array (which gets the callback-array) and a subject. This doesn't work, though ... It appears as if the callback-variant of the preg_replace version isn't capable of handling multiple patterns at a time. This is the error-message I get: "Warning: preg_replace_callback() requires argument 2, 'Array', to be a valid callback in ...". I pass it, as a second argument, an Array that consists of strings containing the names of functions I defined later in my php-file. (Hmmm ... Could that be the problem? Tha fact that I define the functions AFTER I give the Array tot the functions? Don't think so, though ...) Did anybody have the same experience, or am I really doing something wrong? Tnx in advance for any reply!! Bikeman
