This section has details about PHP download locations, and OS issues.
We only distribute precompiled binaries for Windows systems, as we are not able to compile PHP for every major Linux/Unix platform with every extension combination. Also note, that many Linux distributions come with PHP built in these days. Windows binaries can be downloaded from our Downloads page, for Linux binaries, please visit your distributions website.
Note: Those marked with * are not thread-safe libraries, and should not be used with PHP as a server module in the multi-threaded Windows web servers (IIS, Netscape). This does not matter in Unix environments, yet.
LDAP (Unix/Win) : Netscape Directory (LDAP) SDK 1.1.
Berkeley DB2 (Unix/Win) : http://www.sleepycat.com/.
Sybase-CT* (Linux, libc5) : Available locally.
You will need to follow instructions provided with the library. Some of these libraries are detected automatically when you run the 'configure' script of PHP (such as the GD library), and others you will have to enable using '--with-EXTENSION' options to 'configure'. Run 'configure --help' for a listing of these.
First, you will need Microsoft Visual C++ v6 (v5 may do it also, but we do it with v6), and you will need some support files. See the manual section about building PHP from source on Windows.
