This call to ctype_alnum is done by Zend_Filter::isAlnum so it now finds the
class definition. It looks as if i don't have ctype support built in. The
PHP online manual tells me that since version 4.3.0 this should be built in.
I checked my version again, its 5.1.2 (not 5.1.6 as stated first). But still
no ctype support.
"Beginning with PHP 4.2.0 these functions are enabled by default. For
older versions you have to configure and compile PHP with
--enable-ctype. You can disable ctype support with --disable-ctype.
The windows version of PHP has built in support for this extension. You
do not need to load any additional extension in order to use these
functions.
Note: Builtin support for ctype is available with PHP 4.3.0."
I take that line about 4.3.0 to apply to the Windows version of the
pre-compiled binaries, which are configured a certain way at compile time.
The section 'beginning with PHP 4.2.0...' above indicates that for a
stock, from PHP.net source build of PHP that the ctype extension would
be enabled. Your webhost may or may not ( probably not ) be running a
stock, from source build of PHP. More likely they are running a package
that came with their OS distribution and might be configured differently
than the stock PHP.net version.
For example, the FreeBSD port of PHP that I run includes the config
argument --disable-all which shuts off the extensions. I can then
install just the I want ( this is how I have ctype on my system ).
To see a list of what extensions you have access to, do a page with
phpinfo(); in it. You'll get a long HTML page with stuff like
BZip2 Support Enabled
Stream Wrapper support compress.bz2://
Stream Filter support bzip2.decompress, bzip2.compress
BZip2 Version 1.0.2, 30-Dec-2001
ctype functions enabled
date/time support enabled
If phpinfo(); doesn't show ctype then you may want to follow whatever
process your webhost has for people to request additional extensions.
If you look at the top of the phpinfo(); dump you should have a system line
FreeBSD server.domain.org 4.10-STABLE FreeBSD 4.10-STABLE #0: Thu Aug i386
which may tell you the OS, version and architecture which is information
you could use to perhaps help them find the correct extension package
to consider.

p.s. I am aware I use the words may, maybe, likely, probably quite a bit
in this e-mail.. its just the result of dealing with an unknown entity (
your web host ).
