PHP3 String functions not available

[SGaerner@t-online.de (Sven Gaerner)]

Hi!

I have installed PHP3 as cgi- and apache-module on an slink-based machine. I
also have installed some PHP-modules (mysql and imap). When I try to call a
string function (strip_tags) I get an error message in my browser window: call
to unsupported function...
It seems to be that this module is not available but in dselect there are only
PHP3 modules that supports database or graphics functions. How can I use the
string functions??

Thanks for your help...

Bye,

Sven
