LXIV. IMAP, POP3 and NNTP Functions
Introduzione
These functions enable you to operate with the IMAP protocol, as well as the NNTP, POP3 and local mailbox access methods.
Be warned however, that some of IMAP functions will not work correctly with the POP protocol.
Requisiti
This extension requires the c-client library to be installed. Grab the latest version from ftp://ftp.cac.washington.edu/imap/ and compile it.
It's important that you do not copy the IMAP source files directly into the system include directory as there may be conflicts. Instead, create a new directory inside the system include directory, such as /usr/local/imap-2000b/ (location and name depend on your setup and IMAP version), and inside this new directory create additional directories named lib/ and include/. From the c-client directory from your IMAP source tree, copy all the *.h files into include/ and all the *.c files into lib/. Additionally when you compiled IMAP, a file named c-client.a was created. Also put this in the lib/ directory but rename it as libc-client.a.
Nota: To build the c-client library with SSL or/and Kerberos support read the docs supplied with the package.
Nota: In Mandrake Linux, the IMAP library (libc-client.a) is compiled without Kerberos support. A separate version with SSL (client-PHP4.a) is installed. The library must be recompiled in order to add Kerberos support.
Installazione
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. IMAP is not supported on systems earlier that Windows 2000. This is because it uses encryption functions in order to enable SSL connections to the mail servers.
Nota: Depending 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 into the PHP configure line.
