I installed Linux7. It included PHP 4.0.1 pl2. I tried to connect it to a database in the MS Access in another machine with odbc_pconnect. The error happened: "Call an undefined function odbc_pconnect()". What's the problem?
Seems like the odbc support was not compiled in. When configurating PHP, make sure you have something like "--with-iodbc" or "--with-custom-odbc" flag. Use "configure --help" under PHP source directory for more detail.
look at the <? phpinfo() ?> script info and see if there is odbc support in there or not.
