To get these functions to work, you have to compile PHP with `--with-imap[=DIR]`, where DIR is the c-client install prefix. From our example above, you would use `--with-imap=/usr/local/imap-2000b`. This location depends on where you created this directory according to the description above. Windows users may include the `php_imap.dll` DLL in &php.ini;.

Depending on how the c-client was configured, you might also need to add `--with-imap-ssl=/path/to/openssl/` and/or `--with-kerberos=/path/to/kerberos` to the PHP configure line.

The IMAP extension is not thread-safe; it should not be used with ZTS builds.
